Concept of More - Less - Equal

You could use building blocks, rajma seeds or even stones to depict concept of more - less - equal.

Firstly, Make two piles of more and less number of seeds. If the child is fluent in counting, you could ask her to count each of the piles and explain her what more and less are.

Now, make another two piles that contain equal number of seeds and explain to your child that they are both equal.
