Multiplication facts can be listed in a table such as shown here. For Example, the product of 9 and 3 is placed where row 9 and column 3 meet.
Fill in the Multiplication table using the following step-by-step directions.
a. Use the multiplication property of zero to fill in the second row. Now, use the commutative property to fill in the second column.
b. Use the identity property of 1 to fill in the third row. Now, use the commutative property to fill in the third column.
c. Complete the 2 times table:
d. Complete the 5 times table:
e. How many multiplication facts are blank in the table?
