This product is amazing. Easy to handle and help kids a lot. Very usefull in math class and for prompting during homework.

I like the idea of these, but my kid was looking at the shape of the puzzle pieces to find the pair. I covered one edge with a post-it so they couldn't see the puzzle shape, but found that they were matching based on educated guesses (all the numbers on the left piece are in the teens, so I'll pair it with the 15) rather than figuring out the pattern. Once I grouped similar pieces (all single-digit answers together, all teens together, 80's and 90's together) they actually had to figure out the pattern. If you've got a kid like mine, these will require some prep work.

My students love the colors and hands-on practice. I love that they are self checking and fun!

I love using this product for workstations. It is hands-on, and my students are challenged as well.
