Practicing Addition and Subtraction: Activities Bundle

I have finally come to a stopping point on my Adding and Subtraction within 20 Bundle.

I've added the Halloween mystery pictures and Back to School mystery pictures too. 

I am so excited!! There are over 150 pages to use in the classroom including task cards perfect for centers. 

You can find it here.

Here's a freebie! You can print it as an image from here or use this link for Drop Box.
