Maths

Let's start with a dance.smiley
In Maths today we will be subtracting 1's from 3-digit numbers. We will be looking at, and predicting, which digit may change when we subtract the 1's. We will also be using the strategy of number lines and counting back to calculate missing numbers. 
When you have watched the video, have a go at the Busy Ant activity below. Start with Challenge 1 and see how you get one. 
Additional activities can be found on Mathletics.
