Look at the In Focus task. What is the question asking us to find? Can you draw a bar model to represent the information from the question? Now draw the bars for Box A and Box B. You now need to fill in as much information on your model as possible.
Can you see the excess part of Bar A ? It is longer than Bar B. Can you work out this part of the bar? Do you remember when we looked at the legs of a spider and an ant yesterday? Which calculation will we use? Work out how many more rubbers Box A has.
Did you use subtraction? Well done. When you return to school show your teacher your calculations.
Now go onto the calculations in your blended learning book.
