Monday Extra Support - Maths

L.O: To subtract by counting up (M7b/M7c)

Wish 1: I can identify the next multiple of 10.

Wish 2: I can hop to next 10 then on.

Wish 3: I can subtract two 2-digit numbers.

 

Starter task: 

Children are to write the numbers in the book and next to them they are to write the next multiple of 10

e.g. 45 – 50,  123 – 130

 

43 –

28

31

124

178

 

Explain to children that today they will solve subtractions.

Explain that ‘frog’ (an imaginary frog) help us work out the difference between two numbers. He will help us to subtract a smaller number from a larger number!

What are frogs really good at? Jumping! Maths Frog will subtract by jumping!

 

Look at the images below to demonstrate how to work out 43 - 36 = 

 

 Now 63 – 58 =.
Now 165 – 156 =.
