I am a fan of building blocks since I was kid. When I saw SumBlox first time, it totally blowed my mind. It’s an unique block set not only in shapes of numbers, but also the smaller numbers blocks can stuck up to match the bigger number blocks in height. It definitely can help kids to understand the basic math in a fun way. It’s a perfect toy for kids to play themselves, and handy tool for parents to teach them the basic math.
This also can be a valuable education tool in the classroom.
The original idea came from David Skaggs when he was tutoring math class in a local school. It later became a successful KickStarter project. You can purchase SumBlox directly from its online shop. It also comes with lesson books for learning advanced Addition, Multiplication, Fractions, and Adding Fraction with these blocks.
