Appellant Stanette Patricia Crowe challenges her conviction and sentence for involuntary manslaughter under 18 .U-S-C. §§ 1112(a) and 1153, arguing that the district court erred in admitting “other acts” evidence under Fed.R.Evid. 404(b); that it improperly instructed the jury on involuntary manslaughter as a lesser included offense; that the evidence adduced at trial was legally insufficient to establish her guilt of involuntary manslaughter beyond a reasonable doubt; and that her sentence of thirty-two months of imprisonment for that offense was unreasonable under the totality of the circumstances. We have jurisdiction of her appeal pursuant to 28 U.S.C. § 1291, and we affirm.
I. BACKGROUND
In December of 2006, Crowe was residing in Brockton, Montana 1 with Donald Eagleman, their eighteen-month-old son, and Crowe’s father, Stanley. At that time, Crowe was nearly eight months pregnant. On December 31, 2006, Crowe and Eagle-man went to a bar in Brockton to celebrate New Year’s Eve, returning home shortly after midnight.
While at the bar, Eagleman became intoxicated, but did not want to leave the bar and was angry that they had returned home. Crowe asked Eagleman to stay home and tried to keep him from leaving, but Eagleman pushed her down and began hitting her. 2 The altercation between Crowe and Eagleman continued in the kitchen. Eagleman pushed Crowe against the kitchen counter, hitting her with his fist, grabbing her by the neck and repeatedly pulling her back and forth. Crowe then reached, behind her back, grabbed a knife, and swung it at Eagle-man, striking him once. 3 Eagleman then backed away from Crowe, said “I’m out of here,” picked up his coat, and left the residence. Crowe then went to the bedroom and told her father, “I think I stabbed Donald.”
A few minutes later, Eagleman returned to the residence and knocked on the front door. Crowe opened the door and Eagle-man collapsed onto the floor. Having no telephone, Crowe then left her residence to get help. She located her uncle at her grandmother’s house and then returned to her residence, where she found Eagleman still lying on the floor, complaining that it was hard for him to breathe. Eagleman asked Crowe to put pressure on his chest, which she did. Her uncle arrived, observed Eagleman lying on the floor, and then left to find the local police, who arrived at the residence a few minutes later. Eagleman was then transported by ambulance to the hospital, where he was later pronounced dead.
*972 Following an investigation, Crowe was indicted by the grand jury on one count of voluntary manslaughter under 18 U.S.C. §§ 1112(a) and 1153. Crowe entered a “not guilty” plea and the matter proceeded to a jury trial on January 29, 2008. 4
The jury heard testimony from the Government’s witnesses concerning the events of New Year’s Eve, as well as a prior incident in February of 2006 in which Crowe struck Eagleman in the head with a liquor bottle, cutting his ear. At the close of the Government’s evidence, Crowe’s counsel moved for a judgment of acquittal, which was denied. The jury then heard testimony from the defense witnesses, including Crowe herself, and from two rebuttal witnesses. The witnesses recounted the events of New Year’s Eve, as well as prior incidents in which Eagleman had acted violently toward Crowe. Crowe’s counsel renewed the motion for judgment of acquittal, which was denied. After closing arguments and jury instructions, the matter was submitted to the jury. On the evening of January 30, the jury returned a verdict acquitting Crowe on the charge of voluntary manslaughter, but finding her guilty of the lesser included offense of involuntary manslaughter.
Crowe’s counsel filed a written motion for judgment of acquittal, which was heard and denied. The presentence investigation report computed an advisory Guidelines sentencing range of 27-33 months, based upon an adjusted offense level of 18 and a criminal history category of I. At her May 12, 2008 sentencing hearing, Crowe did not dispute those calculations, but requested a downward departure pursuant to U.S.S.G. § 5K2.10. The district court denied that request and imposed a sentence of thirty-two months’ imprisonment, to be followed by a term of three years’ supervised release.
II. DISCUSSION
A. Lesser Included Offense Instruction
In this appeal, we first consider whether in a prosecution for voluntary manslaughter, the district court correctly instructed the jury sua sponte concerning involuntary manslaughter as a lesser included offense after the defendant had asserted a claim of self-defense to the voluntary manslaughter charge.
A trial court may instruct the jury as to a lesser included offense if (1) “the offense on which instruction is sought is a lesser-included offense of that charged” and (2) the “jury rationally could conclude that the defendant was guilty of the lesser-included offense but not of the greater.”
United States v. Torres-Flores,
*973 Manslaughter is “the unlawful killing of a human being without malice.” 18 U.S.C. § 1112(a). Voluntary manslaughter occurs upon “a sudden quarrel or heat of passion”; involuntary manslaughter, on the other hand, involves “the commission of an unlawful act not amounting to a felony, or ... the commission in an unlawful manner, or without due caution and circumspection, of a lawful act which might produce death.” Id. Involuntary manslaughter requires proof:
(1) that the defendant acted with “gross negligence,” defined as “wanton or reckless disregard for human life;” and (2) that the defendant had actual knowledge that his conduct was a threat to the lives of others, ... or had knowledge of such circumstances as could reasonably be said to have made foreseeable to him the peril to which his acts might subject others.
United States v. Keith,
Involuntary manslaughter is a lesser included offense of murder and voluntary manslaughter.
See Amt,
Crowe nonetheless insists that her claim of self-defense negated any theory that Eagleman’s death was accidental or that his stabbing was an unintentional act because she intentionally delivered the stab wound that ultimately caused his death. She asserts that she was legally entitled to do so as a means of self-defense, and argues that in her case, involuntary manslaughter and self-defense are mutually exclusive. But Crowe’s argument falls short of asserting that she intended to use deadly force in striking Eagleman with the knife, ie., that she intended to kill him, and the district court concluded from the evidence presented at trial that a rational jury could find that Crowe intentionally struck Eagleman with the knife, acting in self-defense, but without intending to kill him. 7
Crowe acknowledges that “[a] self-defense theory advanced by the defense can be consistent with a conviction for involuntary manslaughter under some circumstances.”
United States v. Manuel,
The example most easily conceived is where the defendant is assaulted but does not have a reasonable apprehension of suffering great bodily harm or death, and is therefore privileged to use force, but only non-deadly force, in self-defense. See 2 C. Torcia, Wharton’s Criminal Law § 192, at 316-17(14th ed.1979). If the defendant attempts to use non-deadly force, but does so in a criminally negligent manner and death results, then both involuntary manslaughter and self-defense instructions would be warranted, particularly if there is any disputed fact issue concerning the quantum of danger reasonably perceived by the defendant. This situation must be distinguished from the typical case of “imperfect self-defense,” in which the defendant intends to use deadly force in the unreasonable belief that he is in danger of death or great bodily harm. In this circumstance, the offense is classed as voluntary manslaughter. See Skinner,667 F.2d at 1310 ; 2 C. Torcia, Wharton’s Criminal Law § 165, at 262-63 (14th ed.1979).
Id. 8
United States v. Quintero,
While most voluntary manslaughter cases involve intent to kill, it is possible that a defendant who killed unintentionally but recklessly with extreme disregard for human life may have acted in the heat of passion with adequate provocation .... In such a case, the defendant would be guilty of voluntary manslaughter, not murder.
United States v. Paul,
The distinction between voluntary and involuntary manslaughter thus turned on the degree of intent, and if the Government failed to convince the jury that Crowe acted with the intent to kill or that she acted recklessly with extreme disregard for human life, the jury nonetheless could find that Crowe attempted to use non-deadly force in self-defense, but did so with wanton and reckless disregard for human life, causing Eagleman’s death. 9 The jury’s verdict — acquitting Crowe on voluntary manslaughter but convicting her of involuntary manslaughter — comports with the latter conclusion.
That Eagleman’s stabbing was intentional, and not the result of inadvertence or happenstance ie.g., the decedent “falling on the knife” during an altercation, as in Amt and Anderson), does not mean that Crowe intended to cause Eagleman’s death or that she acted with extreme disregard, warranting a voluntary manslaughter conviction. 10 Ample evidence in the trial record, including Crowe’s own testimony, supports the conclusion that Crowe intentionally struck Eagleman with the knife, attempting to fend off his attack, but that she did not intend to kill him. The district court thus did not commit plain error in concluding that a rational jury could so find, and in instructing the jury as to involuntary manslaughter as a lesser included offense.
B. Sufficiency of the Evidence
That same evidence as to Crowe’s mental state refutes her assertion that the evidentiary record at trial was legally insufficient to establish her guilt of involuntary manslaughter beyond a reasonable doubt. Viewing the evidence “in the light most favorable to the prosecution,” we conclude that “ ‘any rational trier of fact could have found the essential elements of the offense[] charged beyond a reasonable doubt,’ ”
United States v. Rosales,
C. The Government’s “Prior Acts” Evidence
Crowe also argues that the district court erred in admitting testimony concerning a prior incident in February of 2006 in which Crowe struck Eagleman on the head with a bottle, injuring him, as “prior acts” evidence under Fed.R.Evid. 404(b) relevant to the issue of Crowe’s intent. Yet even if this court were to conclude that the district court erred in ruling that evidence admissible, any such error proved to be harmless. In acquitting Crowe on the voluntary manslaughter charge set forth in the indictment, the jury rejected the Government’s theory concerning Crowe’s intent or state of mind.
11
In
*976
stead, the jury found Crowe guilty of the lesser included offense of involuntary manslaughter, which they were instructed was “the unlawful killing of a human being without malice aforethought and without an intent to kill.” It thus proves unlikely that the admission of Rule 404(b) evidence concerning the February 2006 incident affected the jury’s verdict.
See United States v. Chu Kong Yin,
D. Crowe’s Sentence
Finally, Crowe argues that her sentence of thirty-two months of imprisonment is unreasonable under Booker
13
and Kimbrough
14
because (1) the district court misinterpreted the facts surrounding the death of Donald Eagleman, ignoring Crowe’s evidence concerning her claim of self-defense and the victim’s behavior that night, as well as his prior violent conduct toward her; (2) the term imposed is greater than necessary to achieve the purposes of sentencing under 18 U.S.C. § 3553; (3) the federal sentencing guidelines routinely “produce a range of sentences that are unconscionably too long”; and (4) the victim’s wrongful conduct contributed significantly to provoking the offense conduct, warranting a downward departure under U.S.S.G. § 5K2.10. Although Crowe concedes that the district court’s calculation of the applicable advisory Sentencing Guidelines range (27-33 months) was correct, taking into account her criminal history reflecting no prior criminal convictions, and that her thirty-two-month sentence falls within that range, she argues that “apart from the rote recitation of § 3553(a) factors and applicable Supreme Court and Ninth Circuit cases,” the district court’s sentencing analysis “was not ‘reasoned’” as the law requires, citing
Rita v, United States,
*977
When reviewing a sentence, we first consider “whether the district court committed significant procedural error,” including an incorrect Sentencing Guidelines determination.
United States v. Carty,
At Crowe’s sentencing, the district court explained that it had considered all of the statutory factors under § 3553(a), and detailed its evaluation of Crowe’s personal culpability and her claim of self-defense, explaining Crowe’s sentence primarily in terms of the nature and seriousness of the offense and the need for just punishment — both of which are statutory sentencing factors under § 3553(a)(1) and (2)(A). 17 The district court rejected Crowe’s argument as to her diminished culpability, explaining that “the conduct of the decedent did not warrant the level of attack that you inflicted upon him with a knife, and the infliction in that process of fatal wounds,” that “such unexcused acts of violence have consequences under the law,” and that the facts did not warrant a downward departure from the applicable Sentencing Guideline range in this case. 18
*978 Crowe disputes the district court’s characterization of Eagleman’s stabbing as an “unexcused” act of violence, but by finding her guilty of involuntary manslaughter, the jury had already determined Crowe’s act to be unexcused, at least to that extent. 19
In arguing more broadly that the federal Sentencing Guidelines routinely recommend sentences that are “unconscionably too long,” Crowe assails them with little more than anecdotes,
20
which by themselves cannot justify excluding the Guidelines
per se
from consideration as one statutory factor under § 3553(a)(4) — just as they were treated in the context of this case.
See Carty,
The district court properly treated the Guidelines range as a baseline, considered the factors enumerated in § 3553(a) in tailoring Crowe’s sentence to suit her offense of conviction,
21
and arrived at a sentence it determined is sufficient, but not greater than necessary, to accomplish § 3553’s sentencing goals — a sentence not more than five months longer than the low end of the applicable Guidelines range, which Crowe had asserted would be an appropriate sentence. As in
Rita,
We thus conclude that the sentence imposed by the district court was given sufficient explanation by the district court to permit effective appellate review, and is substantively reasonable in light of the totality of the circumstances.
See Gall,
AFFIRMED.
. In
Skinner,
the defendant admitted that he had intentionally shot and killed the victim, but argued that he had shot him in self-defense.
Id.
Notes
. Brockton is located within the exterior boundaries of the Fort Peck Indian Reservation and thus is “Indian country” within the meaning of 18 U.S.C. § 1151(a).
. Eagleman also demanded ten dollars from Crowe's father, who had been babysitting the couple's child that evening. After Crowe and Eagleman began arguing, Stanley Crowe retreated to his bedroom with the child and closed the door.
. The deputy state medical examiner testified that the knife penetrated Eagleman’s chest between his ribs near his sternum, puncturing his right mammary artery, which bled nearly three liters into his pleural cavity, resulting in a right hemothorax that caused Eagleman’s death.
. Crowe filed pretrial motions in limine to exclude "other acts” evidence relating to a prior altercation between Crowe and Eagle-man in February 2006, and seeking to admit evidence of Eagleman’s prior violent conduct towards Crowe. The district court ultimately ruled that both sides' "other acts” evidence would be received.
. Crowe’s counsel did not formally object to the court’s proposed lesser included offense instruction at the jury instruction conference; nor did he inform the court of any objection

“we review under our familiar plain error standard.”

United States v. Santiago,
.
On plain error review, before we "can correct an error not raised at trial, there must be (1) error, (2) that is plain, and (3) that affects substantial rights. If all three conditions are met, an appellate court may then exercise its discretion to notice a forfeited error, but only if (4) the error seriously affects the fairness, integrity, or public reputation of judicial proceedings.”
United States v. Maciel-Vasquez,
. As the district court explained in denying Crowe’s Rule 29 motion, “We have a killing that was, by this record, apparently, accidental. That is, she didn't intend to kill the man. But she did stab him, and he died.”
. At trial, there was also a “disputed fact issue concerning the quantum of danger reasonably perceived by the defendant,”
Manuel,
. Crowe did not testify that she intended to kill Eagleman when she struck him with the knife. Nonetheless, Crowe’s counsel appears to equate her intent in striking at Eagleman with the knife with an intent to use deadly force, seemingly suggesting that Crowe should have been found guilty of
voluntary
manslaughter as another "typical case of 'imperfect self defense.' "
Manuel,
. The Government argued that on New Year's Eve in 2006, Crowe had experienced “a flash of anger” that resulted in the stab *976 bing death of Eagleman., and that, like the February 2006 incident, Crowe had struck at Eagleman because she was angry at him, not because she feared for her life.
. Crowe also argues the admission of testimony by an investigating officer concerning the February 2006 incident violated her rights under the Due Process and Confrontation Clauses, citing
Crawford v. Washington,
.
United States v. Booker,
.
Kimbrough v. United Stales,
. These factors include: (1) the nature and circumstances of the offense and the history and characteristics of the defendant; (2) the need for the sentence imposed; (3) the kinds of sentences available; (4) the kinds of sentences and the sentencing range established by the Sentencing Guidelines; (5) pertinent policy statements issued by the Sentencing Commission; (6) the need to avoid unwarranted sentencing disparities among defendants who have similar criminal records and have been found guilty of similar conduct; and (7) the need to provide restitution to victims. 18 U.S.C. § 3553(a). "These factors are to be applied parsimoniously — the sentence must be 'sufficient, but not greater than necessary, to comply with the purposes’ of punishment.”
United States v. Barsumyan,
. A substantively reasonable sentence is one that is "sufficient, but not greater than necessary” to accomplish § 3553(a)(2)'s sentencing goals. 18 U.S.C. § 3553(a);
see, e.g., United States v. Vasquez-Landaver,
. As to these factors, Crowe’s Sentencing Memorandum conceded that "the seriousness of the offense cannot be challenged,” and asserted that “[i]n light of all pertinent sentencing factors, a sentence at or below the low end of the advisory guideline range promotes respect for the law and provides just punishment.”
. In denying a downward departure, the district court also discussed the relative leniency of the applicable guidelines sentencing range in dealing with the killing of an unarmed man using a deadly weapon.
Of course, after
Booker
"the scheme of downward and upward 'departures' [is] essentially replaced by the requirement that judges impose a 'reasonable’ sentence.”
United States v. Mohamed,
. Crowe acknowledged as much in her Sentencing Memorandum: "As the salient facts surrounding the incident unquestionably show, Ms. Crowe’s actions were understandable, if not completely excusable in the jury’s eyes.” (Emphasis added.)
. Crowe points to the Presidential commutation of Lewis "Scooter” Libby’s thirty-month sentence for perjury and obstruction of justice as an example.
. We give deference to the district court’s weighing of those factors.
See United States v. Ruff,
. In
Rita,
the Court affirmed as reasonable a sentence of thirty-three months’ imprisonment for perjury and obstruction of justice.
