Learning Objective
I can use objects and pictures to divide.
Today we will learn how to use objects and pictures to divide. Math helps us solve problems and understand the world around us.
Division means splitting a quantity into equal groups or finding how many groups can be made. Two interpretations: Partition division (sharing equally): 12 ÷ 4 = 3 means share 12 among 4 groups, 3 in each group. Measurement division (repeated subtraction): 12 ÷ 4 = 3 means how many groups of 4 are in 12? Physical models: use 12 objects, divide into 4 equal groups; or use a number line and jump back by 4s. Division and multiplication are inverse operations: 3 × 4 = 12, so 12 ÷ 4 = 3 and 12 ÷ 3 = 4. This relationship is the basis of fact families for 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 use objects and pictures to divide. Keep sessions short (10-15 minutes) and incorporate movement or songs when possible.
