Let’s understand the idea.
- One meter stays the same size, even when a ribbon is longer than a meter.
- The denominator tells how many equal pieces make one meter; the numerator counts pieces.
- A fraction can be written as a whole-number count times a unit fraction.
Something to notice
Ask the learner to point to one meter, then one piece. Can they explain why the number of pieces and the length in meters are different? Ask for a new example without first demonstrating it.
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.
