3 × 11 =
6. If I take off 1 stamp from each row, how many stamps are
there altogether?
3 × 9 = , so
4 × 9 =
If there are 4 rows, how many stamps are there altogether?
4 × 10 =
7. There are 5 pens in each pencil case. How many pens are
there altogether?
5 times 5 =
5 × 5 =
If there are 6 pencil cases, how many pens are there
altogether?
6 times 5 =
6 × 5 =
8. If there are 4 pencil cases, how many pens are there
altogether?
4 × 5 = , so
4 × 6 =
If there are 10 pens in each pencil case, how many pens are
there altogether?
5 × 10 = , so
5 × 9 =
9. Do you know the answer to any of these problems?
