🎯 WALT & Success Criteria

WALT: Read and interpret data displayed in a column graph to answer questions and make inferences.

Success Criteria — I can:

✅ Read data values accurately from a column graph

✅ Compare values and calculate the difference between two data points

✅ Use the graph to make a simple inference or prediction

📊 The Column Graph

The column graph below shows the number of books read by students in Room 12 during each month of Term 2.

Books Read by Room 12 — Term 2

(Column graph with vertical axis labelled "Number of Books" from 0 to 30 in intervals of 5. Horizontal axis shows four months: February, March, April, May. Column heights: February = 20, March = 25, April = 15, May = 30.)

February: 20 | March: 25 | April: 15 | May: 30

Use the graph above to answer all questions below.

✏️ Questions

1. 📖 Reading the Graph — How many books were read in March?

2. 🔍 Comparing Values — Which month had the fewest books read? Circle your answer and explain how you know.

February

March

April

May

I know this because: _____________________________________________

3. ➕ Calculating the Difference — What is the difference in the number of books read between May and April? Show your working.

Answer: _______ books

4. 💬 Making an Inference — The class had a school holiday in April. Does the graph support this? Explain your thinking using data from the graph.

5. 🧮 Total Books — How many books did Room 12 read in total across all four months? Show your working.

Total: _______ books

🌟 Differentiation & Extension

🟢 Support Strategies (for students who need extra help):

• Use a ruler to track across from each column to the vertical axis.

• A number line from 0–30 (counting in 5s) is available on request.

• Work with a partner to read the graph values before answering independently.

🔵 Extension Activity (for advanced learners):

Extension: Room 12 set a goal to read 100 books across the whole term. Did they reach their goal? By how much did they exceed or fall short of their goal? Write a short explanation using evidence from the graph.

Extension: If the pattern from March to May continued into June, predict how many books might be read in June. Explain your reasoning.
