Let’s understand the idea.
- First, tell the story in your own words. What is happening?
- Find what you know and what you are trying to find. Use counters for the objects in the story.
- Act out the change. Check that your answer makes sense in that same story.
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.
