Multiplication tells a group story
Connect groups, objects in each group and the total to a multiplication equation.

Let’s understand the idea.
- Multiplication combines equal groups. Name the number of groups and the amount in each group.
- Division can find how many objects belong in each group, or how many groups can be made. Read what the question asks.
- Keep every object. Equal sharing gives each group the same amount; packing uses the same amount in every group. Check the result with multiplication.
Something to notice
Ask the learner to invent and explain a new context for a product and for each division meaning, using physical objects or their own drawings. The quotient must be interpreted with its unit. These lessons use complete equal groups and exact whole-number quotients; division by zero is never offered. Arrays, measurement contexts, unknown-position equations, properties, mixed problems and fluent recall need further lessons. Guided manipulation and checked answers are practice evidence, not claims of mastery or educator/learner review.
Try it. Change it. Explain it.
Open the lesson to use its pictures and controls. In How it works, connect the picture to the idea. In Play & discover, change the quantities and notice what stays the same. In Your turn, answer questions and use the explanation to check your reasoning.
You can ask for help, draw on the thinking pad, or listen to the question and answer options. Progress distinguishes independent work from work completed with help.
