Let’s understand the idea.
- Read the place labels from millions down to ones.
- A digit is a count of its place unit. In the thousands place, a digit of 6 represents 6 × 1,000.
- Zero keeps a place in the numeral even when that place contributes no value.
- One million belongs in its own seventh place; it is within this whole-number range.
Something to notice
Ask the learner to point to a digit, name its unit and explain its value. Change the digit's place and ask what changes. Look for a distinction between the face digit, the represented amount and the whole numeral. Correct entries are useful practice; invite an explanation with place cards or a drawing.
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.
