Power+Blocks

Power Blocks come in a variety of colors in a box that holds about 250 of them in different shapes and sizes. They are connected through proportions and ratios and can easily be used to teach algebraic thinking and notation, powers of two, relationships between shapes and, besides that, kids just flat out LOVE to build with them.

The shapes are labeled with the beginning letter of the shape (**P**arallelogram, **T**riangle, **S**quare and **R**ectangle) and a number, with the smallest usually being 1--so the five squares you see above would be numbered from S1 (the smallest) to S5 (the largest) (from right to left). Thus, 2S1s =R1 and 2T1s=S1, so 4T1s = R1, OR 2T1s= P1, (with the T1s in a different orientation), so S1=P1 as well.
