Good morning Year 3,

Mr McKenzie misses maths and would like you to solve the following challenges to keep him entertained!

You can write your replies by clicking on the 'comments' button at the bottom of this section.

Question 1

Can you write down all the number bonds to 20?

Question 2 

How many ways can you make 15 using the following numbers only once?

1,2,3,4,5,6,10

e.g 10+5=15

Question 3

I look forward to reading your answers!

      Good morning Micah,

      For question number 2 can you think of anymore ways to make 15. For example, 2+3+10=15.

      Keep up the good work!

      Good morning Orion,

      For question number 2 can you think of anymore ways to make 15. For example, 2+3+10=15.

      For question 3, can you prove that 3 only appears once in the 3x tables?

      It is great to get a response from you! Keep it up.

      Mr McKenzie
