WALT - Subtraction within 10

 

Starter

Task – We have already seen what happens when we take 1 or 0 away from a number, but what about other numbers?

 

Find 8 items from around your home and group them all together.
Now take 6 of these items away … how many have you got left?

 

 

To write this in a number sentence we need to ask ourselves

 

How many objects were there at first?

 

Then what happened to the objects?

 

How many objects are there now?

                                                                            8 – 6 = 2

Task - 

Task - Remember, we can also use our number line to help us with subtraction, by counting backwards.

 

16 – 5 = 11

 

We start at 16 on the number line and take 5 away by counting backwards 5 places

 

 

Using the number line to help you, can you complete these number sentences?

 

  20–3 =         11-6 =

 

  9-8 =           12–4 =

 

  15-10 =        10–5 =
