Look at each array. First write the repeated addition equation, then write the multiplication equation. Remember: multiplication is a faster way to add equal groups!
1.Count the stars. Write the repeated addition AND the multiplication equation.
Write the repeated addition:
+ + =
This is the same as:
Write the multiplication equation:
× =
(3 rows × 4 columns)
How many in all?
2.Count the stars. Write the repeated addition AND the multiplication equation.
Write the repeated addition:
+ + + + =
This is the same as:
Write the multiplication equation:
× =
(5 rows × 5 columns)
How many in all?
3.Count the hearts. Write the repeated addition AND the multiplication equation.
Write the repeated addition:
+ + + + =
This is the same as:
Write the multiplication equation:
× =
(5 rows × 4 columns)
How many in all?
4.Count the stars. Write the repeated addition AND the multiplication equation.
Write the repeated addition:
+ =
This is the same as:
Write the multiplication equation:
× =
(2 rows × 5 columns)
How many in all?
5.Count the stars. Write the repeated addition AND the multiplication equation.
Write the repeated addition:
+ + + =
This is the same as:
Write the multiplication equation:
× =
(4 rows × 2 columns)
