Packing & Planning the Festival Using GCF & LCM

Help your 6th graders finally answer the question "why are we learning this?" This interactive worksheet drops students into a Spring Festival they are running, where greatest common factor and least common multiple stop being abstract steps and become the tools that get the job done. Aligned to Common Core 6.NS.B.4, it pairs a memorable real-world scenario with 18 auto-graded problems and instant on-screen feedback.

What's inside:

• A single connected scenario. Students act as the festival planner solving two real jobs, so the math has a purpose from the first problem to the last.
• 9 GCF "goodie bag" problems. Students find the greatest number of identical bags they can pack from leftover supplies, learning that GCF means the biggest fair share with nothing left over.
• 9 LCM "schedule" problems. Students figure out when two events on different timers next line up, learning that LCM means stacking cycles until they meet.
• A short prompt on every problem that ties the computation to a reason, reinforcing when to reach for GCF versus LCM.
• Instant interactive feedback. As students type, the sheet recalculates: goodie-bag rows show how the items split per bag, and schedule rows confirm the time fits both cycles.
• Auto-graded throughout, scored against the true GCF and LCM so the visual hints guide without giving the grade away.
• Built-in randomization. Regenerate all 18 problems with fresh, grade-appropriate numbers whenever you need a new version.
• A 3-slide story intro that sets up the scenario in student-friendly narrative before the work begins.

Great for introducing or reinforcing GCF and LCM, in-class practice, independent work, sub days, retakes, and differentiated or individualized assignments. Topics: greatest common factor, least common multiple, GCF and LCM word problems, factors and multiples, 6th grade number system, 6.NS.B.4.
