A big multiplication can be split into two small ones. This 3rd grade distributive property missing numbers worksheet uses that idea in three equations, labeled a to c. In each one, a blank replaces a factor. Item a splits 3 × 40 into 3 × 20 and 3 × something, while item b joins 4 × 2 and 4 × 24 into one product. Finally, item c takes 12 × 1 away from 12 × 2. Each item leaves a large grid space for working. A small turtle hangs from a string on the right. Page two writes out every step in pink, like a worked example.
