Set Induction (Attention-Grabbing Story)

Teacher tells a short story:

Teacher: “Last Sunday, my cousin Chika had a birthday party. She bought a big round cake and invited ten of us. But she did something special — she cut the cake into slices to match our favourite flavours. Four slices had chocolate, three slices had vanilla, two slices had strawberry, and one slice had coconut. She called it her ‘cake chart’. Do you know what that reminds me of? A pie chart — a colourful, round chart that shows how things are shared. Today, we will learn how to make one.”

Entry Behaviour

Pupils have previously learned how to represent data using tables and bar charts. They are familiar with counting, addition, and simple fractions.

---

Learning Resources and Materials

• Compass, protractor, ruler, pencil

• Chart paper or cardboard

• Coloured markers or crayons

• Sample data tables

• Lagos State Scheme of Work (Mathematics, Primary 5, First Term)

---

Building Background / Connection to Prior Knowledge

The teacher reminds pupils of the last lesson on bar charts and pictograms. Pupils recall how they used them to show the number of people who like different fruits in their class.

---

Embedded Core Skills

• Numeracy skills – calculating fractions and converting to degrees.

• Data interpretation skills – reading and analysing charts.

• Creativity – colouring and designing the chart.

A. Meaning of Pie Chart

A pie chart is:

1. A circular chart divided into slices.

2. Each slice represents a part of the whole.

3. The whole circle represents 100% or 360 degrees.

4. Each slice is called a sector.

5. The size of a slice shows how much of the whole it represents.

6. Bigger slices mean bigger amounts.

7. Smaller slices mean smaller amounts.

8. We use a protractor to measure angles for each slice.

9. Data must be converted to angles before drawing.

10. It is useful for showing proportions clearly.
