“It is so amazing to find resources that are fun, engaging, and easy to use. This is a great activity to leave with a substitute. It is a quiet activity, challenges the students and takes a while for them to complete. Thank you for your hard work!” · · · “This was a wonderful activity that really challenged my 3rd grade mathematicians. Some even asked if they could borrow the puzzles to bring home over vacation to challenge their siblings! Great product!” · · · My students constantly ask me to take out this activity because they love it so much. They love to have a race to see who can finish theirs the quickest!
