Let’s understand the idea.
- Rename both amounts with the same fractional unit.
- Separate the removed count from the starting count.
- The remaining count has the same unit and can be renamed as a mixed number.
Something to notice
Ask the learner to recreate the starting amount from removed and remaining parts, including zero and whole-number results.
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.
