Turn GCF and LCM into a real job. In this interactive Spring Festival worksheet, students pack fair goodie bags (GCF) and sync ride and show schedules (LCM) across 18 auto-graded problems. Every item connects the math to a reason, with instant feedback as students type. Common Core 6.NS.B.4. Randomization-ready, so each student can get unique numbers.
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:
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.
By completing this worksheet, students will apply the greatest common factor and least common multiple of two whole numbers to solve real-world problems set inside a school festival, in line with Common Core 6.NS.B.4. They will recognize that GCF answers "what is the largest equal share I can make from these totals with nothing left over" while LCM answers "when will these two repeating cycles next line up," and they will learn to read a word problem and decide which of the two tools it calls for. The goal is conceptual as much as procedural: students should leave understanding that GCF and LCM are not isolated calculation drills but practical tools for splitting things fairly and synchronizing schedules, and that the same event can require both.
Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1-100 with a common factor as a multiple of a sum of two whole numbers with no common factor. *For example, express 36 + 8 as 4 (9 + 2).*.

Interactive Grade 6 worksheet where students practice dividing fractions using the Keep-Change-Flip strategy across four progressive sections. 16 problems total, auto-graded with immediate feedback.
Research Station Zero is a multi-worksheet project suitable for Grade 6 and 7 number system, turning the strand into one Antarctic survival mission. Students map a station, average sub-zero temperatures, ration food, calculate fuel and walking distance, pack supplies with GCF and LCM, and brief the commander with their final escape plan. Built for Grade 6, it also works in Grade . Auto-graded, scenario-driven, and Common Core aligned.
Interactive back-to-school math activity. Students turn five personal facts into decimal and fraction practice, then get instant auto-graded feedback. Every worksheet computes different answers because the inputs are the student. Grades 6-8 review. CCSS 6.NS.B.3, 6.NS.B.4.
