Which part of the day out is about the clock, and which part is about the money?

Today we look at problems that mix time and money. Each part gets the right tool: the coin tray on the board for the money, and a clock face at the front for the time.

First watch two money amounts shown on the tray. One is a bus fare, and the other is the change from €2 for a roll. Then we turn to the real clock at the front and count on one hour, from two o'clock to three o'clock. Notice how each tool answers only its own part of the question.

• an apple 30c and a juice €1
• a copybook 60c and a pen 50c
• the change from €2 for a €1.75 spend
• €2.65 in as few coins as you can

First we read the clock at the front together. Look at where both hands sit, name the time, then we move on.

After that we work through these together, each a step harder:

• An apple 30c and a juice €1, how much altogether?
• A magazine €2.50 and a pen €1.20, how much for both together?
• A €1.40 roll paid with €2, find the change.
• The match starts at 2 o'clock and ends at 3 o'clock, ticket €2.50 paid with €5. This one has two parts:
  • the time part, how long does the match last? (Use the clock.)
  • the money part, what change from €5? (Use the interactive.)
