From the seller

Twenty blocks in this attractive set of 24 miniature blocks (size 11/2" x 11/2" x 11/2") has a number, from 1 to 10 on its front, and the question: “How many can you count?” on its back. The remaining four blocks display + signs, and – signs, so that toddlers can start learning the fundamentals of adding and subtracting numbers. Each chunky board block opens to display 8 illustrations of objects for counting. For example, pages of the number 1 block show one panda, one dog and six more single items. Blocks 2 through 5 show two, three, four, or five items per page. Blocks 6 through 10 show the appropriate number of objects across two-page spreads. Accompanying the 24 combination book/blocks is a brightly lithographed board on which toddlers can arrange number blocks and start learning the basics of addition and subtraction. The blocks and board come as a sturdy and good-looking set, packed in a sturdy and colorful case with plastic carrying handle and Velcro tabs to keep it shut. (Ages 1-4)
