Ethan works really well at maths time with his buddies. He can identify numbers 1-20 and some other numbers. He can count out sets of objects to 10, he needs support to count out bigger numbers.
He is playing guess my number and learning to ask questions like "Is the number smaller/bigger than 20?"
We get him to put a number of beans in 1 hand and then 1 more in the other hand to help try and grasp the concept of 1 more.
