Explain how the Grade 3 activity introduces the concept of sampling, using the example of collecting watch and clock pictures from magazines.

Step 1: Identify the population. The population is the complete set of all items being studied. In this activity, it is all watches and clocks in the world. Step 2: Identify the sample. The sample is the subset collected from the population. Learners collect it by cutting out pictures of watches and clocks from magazines. This represents only a small part, not the entire population. Step 3: Explain the purpose. By grouping and analyzing the sample, learners draw conclusions about the population. This shows sampling is more efficient than collecting complete data.
