What you need:
- sticks or straws (To be safe)
- play-dough (to make it more fun
Go for a walk and collect sticks of different sizes. Wash them and dry them.
This was also difficult at first.
Made a pretend TV a sofa with the play-dough. Asked him to make the kids( straws) sit one behind another on the sofa to see the TV but they have to sit smallest to biggest. Showed him how if a tall kid sits in front ,the short kid behind can’t see. So asked him to make them sit accordingly ! and Immediately he got it! He was able to identify heights and position the straws from smallest to biggest !
Given 2 objects he could easily identify the big one and the small one but with more than one he was getting confused. But with this he learnt big, bigger, biggest. Great learning activity and helped me also learn how to teach him better.
