Learning Objectives

Indicator: B4.1.3.2.3 - Provide examples of where fractions are used

By the end of the lesson, learners can:

Identify and name at least three real-life situations in Ghana where fractions such as halves, quarters, and eighths are used.
Explain and act out a scenario involving fraction use, such as selling oil by the half-litre or sharing a cake into eighths.
Read and state times using “half past” and “quarter past” or “quarter to” when shown a clock face.
Interpret a simple circle graph divided into halves, quarters, or eighths and answer questions about the information shown.
Justify their answers by explaining why a particular fraction name (for example, one-quarter) is correct for a given situation.

Exemplars (from the NaCCA curriculum)

E.g. 1. Discuss the contexts below in which fractions are used in real life and provide materials for pupils to act them out
- Selling liquids - oil, kerosene, drinks, etc.
- Sharing pizza or birthday cake - half, quarter, eighths, etc.
- Buying objects in packets - egg, drinks, (half crate),
- Buying cloth for sewing dresses - half, one-fourths or quarter, etc.

E.g. 2. Tell the time by half/quarter past, and half/quarter to. Draw clock-faces with times (i.e. half/quarter past or to) for pupils to read the time
E.g. 3. Drawing circle graphs that represent halves, fourths and eighths. The graph shows the ages of pupils in Primary 4. If there are 40 pupils in the class, ask questions for pupils to interpret the graph
