📚 Part 1: Quick Questions

WALT: Read and interpret data from various graph types.

Success criteria: Identify key data points from column graphs, line graphs, dot plots, and picture graphs, and make evidence-based inferences.

1. Look at the column graph showing the number of students participating in different sports. Which sport has the highest participation?

Basketball

Soccer

Swimming

2. Refer to the line graph depicting temperature changes over a week. On which day was the temperature the highest?

Monday

Wednesday

Friday

3. Examine the dot plot showing the number of books read by students. How many students read 5 books?

2 students

4 students

6 students

4. In the picture graph, each picture represents 2 students. If there are 5 pictures of soccer players, how many students play soccer?

5 students

10 students

15 students

5. In your own words, explain what a trend in data means when looking at a line graph.

A trend in data refers to the general direction in which the data points move over time, indicating whether they are increasing, decreasing, or remaining stable.

✏️ Part 2: Data Interpretation & Short Tasks

6. Analyze the column graph showing the number of hours students study each week. What is the median study time for the group?

Instructions: Look at the graph carefully. Identify the middle value of the study hours represented.

Median study time: [Your answer]

7. Compare the line graph showing monthly sales for two products. Which product had a higher average monthly sales over the year? Provide evidence from the graph.

Instructions: Observe the trends in the graph. Look for the average sales line for each product to compare.

Product A had a higher average monthly sales of 150 units compared to Product B with 120 units.

8. Create a simple dot plot to represent the number of pets owned by students in your class. Label the data points clearly.

Write one clear inference from your dot plot:

This could be because dogs are popular family pets.

9. Reflection (teacher will collect): Write one thing you learned about interpreting different types of graphs and one question you still have.

I learned that different types of graphs can show data in various ways, making it easier to compare. I still wonder how to interpret graphs with overlapping data.

Support & Extension

Differentiation strategies: Provide graph templates, visual aids, or manipulatives for students who need support. Pair students strategically for peer assistance.

Extension for advanced learners: Analyze trends over multiple graphs, calculate percentages for each category, or critique the effectiveness of different graph types in conveying information.
