Let’s understand the idea.
- A count of objects and the measured amount for each object have different roles.
- Build every repeated amount using the same measured whole.
- The total keeps the measure unit, such as metres or litres.
Something to notice
Ask the learner what counts the groups and what measures each group. Ask them to explain the total's unit and, when requested, its location. Physical, oral, child and educator observations remain pending; a correct entered answer alone is not those observations.
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.
