This week for maths we are going to be focusing on finding one less and subtraction again. A couple of weeks a go we looked at this and we are going to practice again. Before we start our session, your warm up is going to be to make a number line from 1-15. See if you can do it all by yourself. I have started to make one below…

Now we are going to look at finding less. Can anyone remember our karate sign for one less? Start by listening to this song and seeing if you can join in. Think about the numbers and how they get smaller by one.

Now we are going to have a go at finding one less by ourselves. All you need is some number cards to 10, objects (pasta, sweets or bricks) and a chirpy robin.

Firstly, choose a number card without looking and then count the right amount of objects out. Then take one away and recount. How many did you have left? Then say one less than… is…. Have a look at my example below.

Then repeat the game again. Choose a number, count out the objects, take one away and recount.

Challenge: Can you write the number sentence that goes along with your one less numbers? I have done them under the end pictures. Have a look and then have a go.
