Odd Numberblock heads appear from a foam ball pit, but where did their bodies go? Number 20 is here to help as we subtract numberblocks and add them to the heads of Numberblocks 9, 7, 5, 3, and 1! Also, let's build the next numberblock that comes after 10 and 20 using various numberblocks we rearrange to create a new rectangle 30! This is a fun toy learning video for toddlers, preschoolers, and early math learners who love adding, subtracting, and the Numberblocks!
