Arthur's Chalkboard Blocks is a series of two sets of wooden blocks made by Fortune East Group in 2011. Each set contains a given amount of wooden blocks, some blank blocks with a chalkboard coating (so that they can be written on), and some chalk sticks. Each set is for ages 3 and up.
The numbers block set contains a total of 30 blocks. Designs on each block include numbers, different quantities of objects, and some Arthur characters.
