For counting by 5’s we started by counting on one hand to see how many set of 5 we needed. Example- 20, need 4 sets of 5, so we made 4 piles with 5 in each. This made it a lot easier and not overwhelming.
You can limit the amount of cereal you use, to make activities go faster. I recommend not doing all of the activities at one time, kids will lose patience/focus too easily by the end.
The best part is you get a snack once you complete the activities as a reward!
