Great for computation within 20. My children enjoy using it for addition and subtraction. I saw some people complained about the sturdiness of the multi-pack units, but the individual student pack, containing just one unit, is good quality.

A great educational product. I got this for my 4 year old granddaughter getting her ready for math.

It does what it claims. It is nice to look at, easy to use and feels sturdy. Would buy again.

This is a good tool. It’s great to help kids look at numbers as groups rather than counting by ones, which is less efficient. Some kids learn better with something they can touch. I really like it. It’s made well. It’s a good size. Not too big or small.

I bought this for an elderly person at a facility to play with, but I noticed that it slid around (wouldn't stay put) on their table while playing. Also, this did not seem as it was constructed perfectly level. I put some glue ("Shoe Goo") on the bottom to add a bit of 'grab' for the table, and used a level to add a tad more to the side that was 'off'. Now its fine and the person enjoys their toy. :-)

My first grader is a tactile learner and this device helped her with math (addition and subtraction) homework in a huge way.

Just perfect will use this to count my lap in the ymca pool!!!!

I tried touch math, hundreds chart, number line, counters, tallies, but this was finally the solution for a student who tended to be off by one number. I also love the color coding by 5’s to increase speed.

Very sturdy and well made.
