Here is our class tuck-shop price list: a pencil is 30c, a rubber is 20c, a sticker is 50c and a juice is €1.

If you had €1 to spend, which two things could you buy?

Watch two spending plans on the budget bar. First plan: €1 to spend, a pencil at 30c and a rubber at 20c. The bar shows 50c spent and 50c still to spend, so this plan fits.

Second plan: €2 to spend, a sticker at 50c and a juice at €1. The bar shows €1.50 spent and 50c still to spend. Notice how we work out the total first, then read what is left.

Now we build spending plans together on the budget bar. The items are pencil 30c, rubber 20c, sticker 50c and juice €1.

Your teacher will set the money to spend and name two items. Step each one up to its price, then work out the total and how much is left before you read the bar.

Today we answer four spending questions from the tuck-shop list, together on the board. The prices are pencil 30c, rubber 20c, sticker 50c and juice €1.

We work through these in order: a pencil and a sticker together; with €1, a rubber and a sticker; a juice and a rubber, checking whether their total is more than €1; and with €2, a juice and a pencil, then work out the change. Each one adds a little more to think about.
