Let’s understand the idea.
- One whole is the fixed distance from zero to one on this scale.
- New tick marks do not move the selected endpoint.
- The same reasoning works across whole boundaries; the current display shows up to twelve wholes.
Something to notice
Ask the learner to locate the original whole, selected point and new unit interval. Can they explain why changing tick counts cannot move the number? Further larger-whole tasks remain a separate depth obligation.
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.
