One of the most popular math centres in my classroom this year were my number sense trees which I introduced in the early fall for practice.
The only problem was that they were only good for 1-10 review, which was fine in September, but in October/November we were studying 1-20, and they didn't help reinforce the same skills for the higher numbers.
I've fixed up the set, now offering 1-20, but also individual sets for the original 1-10, and 11-20 as a stand alone set, depending on your students skill sets, and the sequence you teach math skills.
I've also included a few more types of cards to sort on to the matching trees.
NEW: Tens and Ones
The font has been changed to a much more child friendly font as well. I LOVED my previous choice, but this is better for this product.
Here's a student trying to sort the cards onto the original version:

I'm thinking of making an additional set for numbers to 100, but have the trees be tens instead of individual numbers, what do you think? I don't think I've seen anything like that available else where.
