## Benji has been growing his maths brain!

Morning all, today we are looking at doubles, using our number bond knowledge to add three single digits together. As a starter to get your brain moving count up in 2s. Ask someone to drop pasta or lego into a cup and then double the number.

Task one: Mild

You will need two sets of cards with 1 - 9 written on them. Pick three cards (two of which must be the same number) e.g.

2 + 2 + 5 = Identify and work out the double first. 2+2 = 4. Now add the third number 4 + 5 = 9.

You can use pasta or lego to help you. Now pick three more cards remembering to have two cards the same digit. Continue until you feel confident.

Task two: Hot

Complete these additions. You can use lego or pasta to help you. What do you notice about these additions? Remember we are looking to use our number bond knowledge. Talk about what you see with someone and explain in words what you do to answer these questions.

6 + 8 + 6 = | 4 + 8 + 4 = | 3 + 8 + 7 = |

7 + 7 + 5 = | 5 + 9 + 5 = | 8 + 4 + 6 = |

4 + 7 + 6 = | 9 + 9 + 6 = | 9 + 8 + 2 = |

7 + 9 + 7 = | 1 + 8 + 9 = | 6 + 9 + 4 = |

2 + 5 + 5 = | 7 + 8 + 8 = | 3 + 6 + 7 = |

Task three: Spicy

**Can you score 16 points?** Play Magic 16 using these rules:

How many sets of three numbers can you write that have a total of 16? Score 1 point for each set. Score an extra point for any sets that contain a double. Score an extra point for any set that contains a number bond to 10.

Task four:

Answer these questions using doubling. You will do this by partitioning the number into tens and ones. We use the house method at school so look at the picture below to recap how we do it.

24

20 4

40 + 8 = 48

Have a go at doubling these numbers:

13 | 21 | 12 | 24 |

14 | 31 | 41 | 25 |

Once you are feeling confident, using your number cards 1 - 9 create your own two digit number and double it.

**Task five: **

These numbers have been doubled already. Can you work out what the original was?

Explain how you have worked these out.

30 | 64 |

86 | 42 |

True or False: I have doubled 23 and my answer is 47.

I have doubled 63 and my answer is 125.

I have doubled 14 and my answer is 28 .

Explain your answers.
