- Reviewed in the United States on January 21, 2021We love these cubes! They're perfect for hands-on learning to teach a variety of math concepts, such as patterns, place value, addition, subtraction, fact families, and more. Both my kindergartener and my first grader use them to practice concepts. The fun colors help keep my kids engaged, and they also love it when I let them "build" with the blocks after they complete their math work.
- Reviewed in the United States on June 17, 2020Bought these for my 6 year old to help with math. The book included gives a lot of other activities that can be done with the set. Would definitely buy these again, or even another set as we keep moving up with our math skills. Great supplement to the traditional abacus that we use and has really helped with home school math activities so we don't have to use items around the house anymore. Arrived super fast.
- Reviewed in the United States on January 25, 2025They're great. Really good quality and I do like them so much, but as a pre-k teacher, I do a lot of color classification and identification and there aren't any cubes that resemble purple. There's a strange red-brown that I wish was purple instead.
- Reviewed in the United States on May 26, 2020I ordered some of these to use while teaching my niece basic math during the pandemic. She has said they work great... just like the ones at school. Others have reviewed them as not holding together tight enough but we did not experience this issue at all.
