48 stickers.

[/quote]First u draw 3 units for Shaun and below that you draw 1 unit for Jason.
Transfer 1 unit over from Shaun's to Jason.
That makes them both equal units of 2 each.
Since 1 unit is 24, Shaun has 2 more units than Jason at first, you take 24X2=48.

You can use this explaination and guide your child to draw the model by himself/herself and explain step by step.

Can someone show me how to solve the following question using the model.


Mrs Lee bought 35 blue and red hair clips. She then packed them equally into 5 packets. If there are 3 more pink clips than blue clips in each packet, how many blue clips are there in each packet?

Thanks

Thanks

First, each packet will have 35/5 = 7 clips.

Now draw model, draw 1 unit block to represent blue clips, and then the same unit block with another block of 3 clips to represent pink clips.

As total is 7 clips, so the 2 unit block will be 7 - 3 = 4 clips.

Finally, 1 unit block = 4/2 = 2 clips.

Ans: 2 blue clips in each packet.
