M is just not interested in numbers. He can say his numbers in order to 10, but number recognition, and counting correctly above 2 or 3, as well as his one-to-one correspondence skills need a little work.
To that end I whipped up these fun little cards. They can be found here from childcareland.com. And they go up to # 20. I've made 1 - 10, but we only work on 1-4 currently. They are for a pom-pom counting book, but I printed them out on cardstock and laminated them to make individual cards. I bought cute little novelty erasers at Dollar Tree (30 for $1.00!), and we use them for manipulatives. It's pretty simple - just name the number on them, then count out loud with him as he places the erasers/markers on the circles.
The cards also have the number written out for those who are learning number words.
Enjoy! And have a beautiful day! :)
