Knowledge
Students know:
- When any factor, x, is multiplied by a factor of 1, the product is the value of x.
- If one factor is zero, then there are zero groups or zero items in a group and the product is zero.
- The commutative property of multiplication shows a x b = c and b x a = c.
- The associative property of multiplication shows that when multiplying three or more numbers, the product is always the same regardless of the grouping.
- The distributive property will help in finding products of more difficult multiplication facts.
