Today we would like you to get a given number of objects.
Ask your child to get different amounts of objects e.g. 3 cars, 5 pencils, 1 book etc.
If they grab handfuls, then show them how to count each one individually as the give it to you. If they don't stop at the number you ask get them to count first and then put you hand up to show them to stop.
So, if you want 3 teddies and they don't stop count 1, 2, 3, (Put hand up to stop).
