Key facts behind this multiply tens worksheet
- A multiple of 10 is a whole number of tens, such as 30 (3 tens) or 80 (8 tens).
- Multiply the basic fact first: 9 x 8 = 72, so 9 x 80 = 720.
- The answer is that many tens, so the product ends in 0.
- If the basic fact ends in 0, the product ends in two zeros: 5 x 60 = 300.
- Skip counting by the multiple of 10 gives the same answer.
