# SUBTRACTION – COUNTING ON TO TAKE AWAY?

This morning you will be learning another strategy to do subtraction.  We will be counting on to take away by finding the DIFFERENCE between the two numbers using the empty number line.

•  We will be playing a game called CONVICT COUNT ON to explain how this strategy works in a fun way.
• You can have a go on your own later or at home to use the strategy online with this SUBTRACTION ON A NUMBER LINE activity.  You can change how big the numbers are that you have to subtract and you can actually see the jumps.

You can also watch a couple of videos I made of this lesson, using an Empty Numberline to count on and count back to subtract.  You can find it on Dolphinkids by following these instructions:

This makes subtraction SO EASY!  🙂

Let me know how you go.

# Adding two or three digit numbers – with regrouping

This animation (which you can find on “Maths Tools – Adding 3-digit numbers”) might help you to understand how regrouping works.

This works for 2-digit numbers, 4-digit numbers and so on…

Practise using this and challenging yourself using paper too, to see if you can do as well as the computer and get them correct.

# Maths – Flip, Turn, Slide (Transformations)

### Today we are going to learn the Maths words: flip, turn and slide to transform shapes.  Watch this YouTube video demonstrating these transformations.  The triangle will flip, turn and slide.  Then you will make your own!

After that you will be working on your Symmetry Booklet to do these transformations!
