Egg Carton Fun

Egg Carton Fun is a Grade 4 factors activity that helps students explore how one number can be regrouped in several equal ways. Using counters or beans and an egg carton, students represent factor pairs such as 2 groups of 24, 3 groups of 16, or 6 groups of 8. The physical regrouping makes factors visible as arrangements instead of only a list of numbers.

Use it in small groups when introducing factors, divisibility, or the idea that composite numbers can be decomposed in multiple ways. Students can compare representations and explain why each arrangement leaves no remainder. Create a free Find a Math Game account to generate lesson support for Egg Carton Fun.
