Multiplication is...​

adding a number over and over again.​

Multiple Choice

Which expression represents what happens in multiplication?

• $$20\ \div\ 5\ =\ 4$$  

• $$4\ +\ 4\ +\ 4\ =12$$  

• $$3\ -\ 3\ =\ 0$$  

• $$3\ +\ 2\ =5$$  

​There are a few special rules with multiplication:

• Any number multiplied by 1 is equal to itself.

​

• ​When you multiply by 2 you add the number to itself. Any number multiplied by 2 will end in an even number.

​

• ​When you multiply by 5 you can skip count by 5 to get your answer. Any number multiplied by 5 will end in a 5 or a 0.

​More multiplication rules:

• ​When you multiply by 10 you take the number you are multiplying by and put a 0 behind it.​

  • ​

• ​When you multiply by 11 you take the number you are multiplying by and rewrite the number twice.
