Learning to Multiply by 5s

 

Five's trick:  Any number multiplied or divided by 5 will end in 5 or 0.

Learning the 5s
 5 x 0 = 0  5 x 7 = 35
 5 x 1 = 5  5 x 8 = 40
 5 x 2 = 10  5 x 9 = 45
 5 x 3 = 15  5 x 10 = 50
 5 x 4 = 20  5 x 11 = 55
 5 x 5 = 25  5 x 12 = 60
 5 x 6 = 30  

 

A fun way to learn the 5s times table is to skip count ...

0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60

Be sure to practice skip counting backwards !

60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0

Learning to Divide by 5s

Do you remember that the sign ÷ means divide?  When we see the ÷ sign we say divided by.  Division is a type of reversed multiplication. It just takes a wee bit of practice.
(NOTE: 0 divided by any number equals 0)

Be sure to practice skip counting as it helps us to divide quickly ...

0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60

Be sure to practice skip counting backwards !

60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0

Before you go on to the 1s times tables, be sure to ...

1)  Review your skip counting ... frontwards and backwards

2) Have your daddy, mama, sister, or brother flash
you the 2s multiplication/division facts.
See how fast and accurate you can be !

3) complete the Multiplication Chart for what
you already know !
