3rd grade Multiplication

Multiplication syllabus for 3rd grade

3rd grade multiplication expects you to know your multiplication tables up to 12 x 12. In the "Mental arithmetic" sub-category you practice multiplying 2 and then 3 single digit numbers in your head. In "One-step problems" you can practice the formal written method of short multiplication using 2x1 and 3x1 short formal multiplications. Distributive laws enable you to break down a larger multiplication into a pair of smaller, simpler sums such as 39 x 7 = 30 x 7 + 9 x 7. "Two-step problems" involves problems regarding numbers of combinations of 2 or 3 categories of items.
