LO: To know how to subtract a 1-digit number from a 2-digit number using a number line.
Today we are going to look at subtracting a 1-digit number from a 2-digit number using number lines.
You will need a pencil and square paper.
We will look at working out 38 – 9 =
First we will draw a number line and jump back 9
Draw number lines to work out:
23 – 7 = 54 – 3 = 43 – 7 =
51 – 6 = 46 – 8 = 37 – 9 =
Remember to put the largest number at the end of the number line and jump back the smallest number.
Here is another example:
Bertie has 31 treats, he gives 6 to Max.
How many treats does he have left?
Write out the number sentence then show your working out on a number line.
