In year 3 we have started to use bar models to help with problem solving. Look at the following explanation and then draw your own bar model to solve the problems below.

The Ninjagos have to deliver 358 leaflets for their tea shop. They have delivered some and have 289 left to deliver. How many leaflets have they delivered?

Princess Aurora and Princess Tiana have 200 beads altogether. Tiana has 40 more beads than Aurora. How many beads does Tiana have?

There are 71 princesses at the ball. There are 29 more princesses than princes at the ball. How many princes are there at the ball?

The calculations were a little challenging but I managed to get themy right.Also they were fun.

This is a very good technique but using ratios may be more helpful.

I found it quite hard at the beginning and then it got quite easy.

this is a very good technique but using ratios may be more helpful.

AWSOME WORK
