Critical Thinking sent us Balance Benders! At first, I wasn't sure what to expect from this company, but the kiddos and I both have been impressed with the product we received! We were sent Balance Benders. It is a challenging book for all of us...definately makes you think!
The kiddos and I have enjoyed doing these challenges and we will be going back to Critical Thinking for more challenging books!
