Multiplication x11

Lesson

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

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

Remember!

Any number multiplied by $$1 is itself.

e.g. $$1×5=5, $$1×12=12, $$1×100=100 and so on.

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

$$10×6 $$= $$60
$$1×6 $$= $$6
So $$11×6 $$= $$60+6
  $$= $$66
