Mathematics - Term 1 - Week 8

Data handling is the process of collecting, organizing, and interpreting information. In our daily lives, we encounter data everywhere, such as in surveys, weather reports, and sports scores. This week, we will learn how to gather data, represent it visually using charts and graphs, and analyze it to answer questions.

Let's say we surveyed our class about their favorite fruit. The results were: Apples - 5, Bananas - 3, Oranges - 4. To create a bar graph, we will draw a horizontal line for the fruits and a vertical line for the number of votes. We will then draw bars for each fruit according to the number of votes. This visual representation helps us see which fruit is the most popular at a glance.

Now, let's conduct a survey in class. Each student will choose their favorite color from a list: Red, Blue, Green, or Yellow. After collecting the data, we will tally the results on the board. Then, we will work together to create a bar graph based on our findings. This will help us practice organizing and interpreting data as a class.

For independent practice, you will receive a worksheet with a set of questions related to data handling. You will need to create your own bar graph based on a given set of data about pets owned by students in your class. After that, answer questions about the graph, such as which pet is the most common and how many students own dogs.
