Let’s understand the idea.
- Read groups of three digits with their scale name, such as thousands.
- A zero place does not add a spoken hundred or thousand, but the numeral may still need that placeholder.
- To write a numeral from a name, put each quantity into its correct place before checking the zeros.
- Zero and one million have their own complete names.
Something to notice
Ask the learner to read a new numeral, write it from a spoken name and point out its zero places. Accept natural whole-number wording, then check that the place meaning is right. These written tasks practice number names; listen separately for confident reading and an explanation of the placeholders.
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.
