Teach children with a 1 to 100 times table chart by using strategies such as skip counting, the commutative property for multiplication and looking for patterns. To construct a 1 to 100 times table, place a row at the top and a column down the left side with the numbers from 1 to 10, and fill the products of these different rows and columns into the matching cells of the table .

For example, when working with the two times table (2, 4, 6, 8, 10, 12, 14, 16, 18 and 20), explain that children can use skip counting by two to find the products from 2 x 1 = 2 to 2 x 2 = 4 and successive multiplications by 2 down or across columns. Similarly, skip counting can be used for the other times tables.
Another times tables strategy is to show that the intersection of a specific row and column gives the product of the multiplication of these two numbers. To find 5 x 4, go down to where the 5 is located at the table's left side, find 4 at the top of the table and move down five spaces to get the product of 20. Students can also learn about the commutative property of multiplication, such as how 4 x 5 and 5 x 4 both equal 20. This also relates to the fact family for 4, 5 and 20 for both multiplication and division.
There also are specific patterns to look for on the 1 to 100 times table, including multiplications by 10 that give products that end in the digit zero and multiplications by 9 that result in products with digits that add up to 9.
