Multiplication x11

Lesson

If you know your 10 times tables and you know your $1$1 times tables, then it won't be too hard to learn your $11$11 times tables! We know that $10+1=11$10+1=11 and that multiplication is looking at equal sized groups.

So $10$10 groups plus $1$1 group equals $11$11 groups!

Remember!

Any number multiplied by $1$1 is itself.

e.g. $1\times5=5$1×5=5, $1\times12=12$1×12=12, $1\times100=100$1×100=100 and so on.

So if we're given a question, such as $11\times6$11×6, we could think:

$10\times6$10×6 | $=$= | $60$60 |

$1\times6$1×6 | $=$= | $6$6 |

So $11\times6$11×6 | $=$= | $60+6$60+6 |

$=$= | $66$66 |
