This set is helping children learn numbers as they mimic the hands at the blocks. Counting on fingers is a child’s first necessary enjoy with number sense – these blocks make that have concrete and tied to the written numbers. The 1.5″ wood blocks alternate between maple and walnut for the extraordinary or even numbers. We seal each and every block with our own jojoba oil/beeswax blend. Secure for every age, even teething little ones.
