What does this exercise practice?
This task supports the understanding of the number order up to 100 and shows that numbers are spaced evenly along a line.
Common pitfalls
Children sometimes skip a number or write numbers in the wrong order. It helps to first read the numbers already there out loud and then name the gap.
How to practice at home
On a walk, watch the house numbers on one side of the street: which one is missing? That makes the number line lively and tangible.
