Mathematics - Term 3 - Week 4

Data handling is the process of collecting, organizing, and interpreting information. In this lesson, we will learn how to gather data about our class and represent it using simple charts. For example, we can ask our classmates about their favorite fruits and then display the results in a bar chart. This helps us see which fruit is the most popular!

Let's say we asked five students about their favorite colors. The answers were: red, blue, blue, green, and red. We can organize this data into a bar chart. We will draw a bar for each color: two bars for red, two for blue, and one for green. This visual representation helps us quickly see that blue and red are the most liked colors in our class.

Now, let's conduct a survey in class! I will ask each of you to tell me your favorite animal. As you share, I will write down the answers on the board. After we collect the data, we will work together to create a bar chart. Remember to count how many students chose each animal and draw the bars accordingly. This will help us visualize our class's preferences!

For your independent practice, I want you to ask three family members about their favorite snacks. Write down their answers and then create a simple bar chart to represent the data. Make sure to label your chart clearly with the names of the snacks and the number of votes each one received. Bring your charts to class tomorrow so we can discuss them!
