I recommend that you put the tray there and let your child discover it on his own and let him do whatever he wants before turning into a counting game, etc.
You can use this monkeys in many different ways here are a few suggestions:
- Math: Use it with number cards. Let the child to draw a number card and he has to hang the same amount of monkeys in the line. You can also use a dice instead of number cards.
- Sensorial: Make a monkey chain first one, then two, etc. Then you can talk about which one is shorter and which one is longer.
