You have spent a whole year (and the year before that) building up your maths. Today we take one last tour through the five big areas of maths: Number, Measures, Shape and Space, Data and Chance, and Patterns and Rules.

Here is the question to hold in your head for the whole lesson: where does the very same idea show up in two different areas?

One big idea from each maths area, side by side on screen. Read each snapshot and be ready to say which area it belongs to. Watch closely — two of them turn out to be the very same idea.

Today we plot together on the grid. We will place four points in the order they were called: (2, 5), then (5, 5), then (5, 1), then (2, 1). Predict what shape those four points will make before we join the last one.

Now an idea-spotting investigation. On the board is one real classroom situation: planning a small class treat. Your job is to spot which area of maths each question below belongs to, and to notice the one idea that lives in two areas at once.

• How much does the treat cost per pupil if 28 share €224?
• Which snack is better value: €4.20 for 6 or €0.80 each?
• How much floor space do we need to lay out the tables?
• What fraction of the class chose fruit over crisps? What percentage is that?
• We buy 3 packs on Monday, 6 on Tuesday, 9 on Wednesday. What is the pattern, and how many on Thursday?

For each question, name the area of maths. Then find the question whose idea belongs to two areas, and say which two.

Turn to a fresh page in your maths journal. Draw the five areas of maths as five headings: Number, Measures, Shape and Space, Data and Chance, Patterns and Rules. Under each, write one idea from this year you now feel sure about. Then, in one sentence at the bottom, name the area you think needs a little more practice — and why.
