My kids love this activity from Imagination Tree. (Free idea!)

Sort and Count Maths Bottles

Instead of numbers write the color word on the bottles. Sort pom-poms by color. Empty each bottle and count the pom-poms. Then record how many pom-poms were in each bottle. Add the two colors together for addition practice.

Make a count and sort posting box for fine motor practise and problem solving. The enduring appeal of dropping and posting through holes will make this a real favourite game.

The Imagination Tree: Count and Sort Posting Box Maths Game. Great idea for toddlers.
