Let’s understand the idea.

- Track equal pieces, not just a written rule.
- Reconstruct the original measure to check a generated name.
Something to notice
Observe the first attempt on the unfamiliar pair before support. Ask for a visual justification. Repeated questions in later recall remain useful practice but are not fresh-transfer evidence.
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.
