Share it in two parts
Use two known divisions to share one total equally.

Let’s understand the idea.
- Choose two parts that make the original total. Share both among the same number of groups.
- Find what one group receives from each part. Add those two amounts to find what one group receives altogether.
- A different split can help you use facts you know. Keep the total and divisor unchanged while comparing splits, then check with multiplication.
Something to notice
Ask the learner to choose useful dividend parts, explain why the same divisor applies to both, and check the final per-group amount against the original total. Six questions require both partial quotients and their sum; three use numerical responses and one probes invalid splitting of the divisor. This model uses exact whole-number shares within 100, with no remainders. Broader fluency, mixed word problems, other domains and educator/learner review remain separate work.
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.
