Now that we’ve remembered how to create number fact families, using our magic triangle to write 4 number sentences: 2 addition and 2 subtraction, we’re ready to explore NA8 – Addition and Subtraction Facts today.
Practise testing yourself at home until you know them automatically without working each one out. This will make all your maths calculations so much easier! 🙂
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.
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.

Today in Rotating Maths Groups the computer group will be flipping their learning. Today you will watch the lesson on subtraction on video and practise the strategy on whiteboards, before working with the teacher to show what you have learnt when you reach that session.
You can rewind as many times as you like until you understand the strategy and can do it yourself.
Enjoy flipping your learning. You’ll find it’s easier and even more fun than backflips! 😎
