## The Tallest Tower

Students, have you ever seen a game called jenga? It is played with rectangular wooden blocks. The game is played by stacking the blocks in a tower and then carefully pulling out one block at a time, hoping that the tower won't collapse!

Jenga

Have you ever been to a shoe store and seen how the shoes are stacked on top of each other? They usually have a broad base and are arranged so that they don't fall over.

Let's talk about which shapes can be stacked on top of each other and which ones can't.

When we stack shapes on top of each other, we want to make sure that they are stable and won't fall over. Shapes with flat surfaces like matchbox, erasers etc. are easy to stack because they have a broad base and can be placed on top of each other without falling.

However, some shapes are more difficult to stack. Shapes like ice cream, ball etc. are not as stable because they don't have a flat base.
