Set of 500 Centimeter Cubes with Storage Container - Mathematics Learning Tool & Educational Teacher Resource for Sorting, Measuring, Counting, & Base-10 Units by Pint-Size Scholars

Taught my 3 year old to count and kept him busy for hours on end. Superb product. Highly recommended

These are great little cubes. We bought them to use in place of enemy miniatures for our gaming when on the road and cannot afford real miniatures. The bin they come in a good plastic and reusable, and out of 500 cubes only one was color issues (one of the whites had some yellow color bleed on it).One note, there is effectively only 9 colors as for someone with my skill of color vision the two shades of green are close enough as to be indistinguishable.

I bought these for grade 1 math work with my daughter. They're perfect for doing base-ten work, adding subtracting, and other simple math. As mentioned in another review, there are dimples in the plastic, but I don't see any reason to take away a star for that as it doesn't impact the use of the cubes. They don't snap together, but never advertised that they would. The price was a fraction of what other brands cost, so I'm very happy with them.

My son is 4 going on 5 soon, and I use these to help him with counting and color grouping. They are very small so my younger girls are napping when these are out. For him they are perfect and fun.

The math cubes are great for base ten blocks. However, they do not connect together. Other than that, great for counting and patterning work.
