Two effective manipulatives that can be used to support fractions and base 10 learning are base 10 blocks and Cuisenaire rods ...

Look carefully! Mathematicians have invented a new 13-sided shape that can be tiled infinitely without ever repeating a pattern. They call it "the einstein." For decades, mathematicians wondered if it ...

Remember the graph paper you used at school, the kind that’s covered with tiny squares? It’s the perfect illustration of what mathematicians call a “periodic tiling of space”, with shapes covering an ...

Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly ...

Hunt for shapes and make familiar objects by putting together several different shapes. Warm up with a Mystery Math Mistake to tell whether Dotson's 10-frames represent a number more than his focus ...

The same researchers behind the 13-sided "hat" shape have stumbled upon a version that improves upon the original in a very important way. Reading time 2 minutes In March, a group of mathematicians ...
