Let’s understand the idea.
- Name the measured object and its unit.
- Changing units keeps the original amount. One plot mark records one object.
- Use the story to decide how measured amounts are combined or shared.
Something to notice
Real measurement requires observing use of an actual ruler; record precision, object identity and any assistance. Digital placement alone is not physical measurement 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.
