My kiddo just turned two last week and it was time for us to send him to play school. To make him understand words, I bought Mini Alpha board. He is slowly getting to understand words and Mini alpha board is a useful resource. Its easiest way to evaluate ur kids grasping of words. When I give him A, B and T and ask him to form words, he will end up writing bat and tab. It has numbers too. It is extremely useful for kids under the age of 4 and highly recommended.
My kid is 2 years 4 months going to playschool. He likes this a lot and very much interested in using board and chalk. He likes to rub it off often after scribbling.
