Every number has a predecessor (one less) and a successor (one more).
Example: The neighbours of 50 are 49 and 51.
49 ← 50 → 51
Sometimes the number in the middle is missing too, find it!
The numbers already filled in show the solution.

What does this exercise practice?
This task strengthens the understanding of the number order up to 100 and shows that every number has a fixed place before and after other numbers.
Common pitfalls
Children often stumble at the tens boundaries. The neighbours of 50 are 49 and 51, those of 70 are 69 and 71. Pay special attention to crossing the tens.
How to practice at home
Name a number and let the child name the neighbours. Whoever answers quickly gets a point. That makes the game lively.
