# Y4 Maths- Thursday 23rd April

Good morning year 4,

Lots of fantastic work on perimeter yesterday so today you have a challenge! You need to calculate the perimeter of the shapes by using the lengths of the sides and adding them together. Remember the perimeter is like a fence.

You will need to use column addition as there are quite a few numbers to add.

I have made two levels of work today so decide which one you would like to complete based on how confident you are. Easy is the blue shapes and hard is the red shapes.

Happy learning!
