Learning Objective
I can divide by making equal groups.
Today we will learn how to divide by making equal groups. Math helps us solve problems and understand the world around us.
Equal groups are the foundation of multiplication. When objects are arranged in equal groups, count them efficiently by skip counting or multiplying. Example: 4 groups of 3 objects = 3, 6, 9, 12 (skip count by 3 four times) = 12. An array is a rectangular arrangement of objects in rows and columns. A 3 × 4 array has 3 rows and 4 columns = 12 objects. Arrays show that multiplication is commutative: 3 × 4 = 4 × 3 (rotating the array). Equal groups thinking leads directly to multiplication and division.
Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!
Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.

Teaching Tip
For younger learners: Use concrete objects and hands-on activities when teaching divide by making equal groups. Keep sessions short (10-15 minutes) and incorporate movement or songs when possible.
