Division and Multiplication


You can get both a multiplication fact and a division fact from the same picture:
Three groups of 4 is total 12.3 × 4 = 12



12 divided into groups of 4 is three groups.12 ÷ 4 = 3

Two groups of 6 is total 12.2 × 6 = 12


12 divided into groups of 6 is two groups.12 ÷ 6 = 2
Five groups of 2 is total __.__× 2 =__





__ divided into groups of 2is ___ groups.__÷ 2 =__
One group of 4 is total 4.__× 4 =__
4 divided into groups of 4 is one group.__÷ 4 =__
__ groups of     is total __.__×__ =__
__ divided into groups of     is ___ groups.__÷__ =__
Five groups of 1 is total 5.__× 1 =__
5 divided into groups of 1 is __ groups.__÷ 1 =__
__ groups of     is total __.__× __ =__







__ divided into groups of    is ___ groups.__÷__ =__

Multiplication and division are very closely related.  They are the opposite operations.
You could say division is "backwards" multiplication.
