Let’s understand the idea.
- Two halves make the whole. Four fourths make the whole.
- A fourth and a quarter mean the same share: one of four equal parts.
- Keep the whole the same size. Splitting it into four equal shares makes each share smaller than splitting it into two.
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.
