Grade 4 Data Science · Reading & Building Line Graphs
Use the data below to answer the questions.
| Month | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Temp (°F) | 32 | 35 | 45 | 55 | 65 | 75 | 82 | 80 | 70 | 58 | 44 | 34 |
① What is the overall trend from January to July?
Circle the trend above, then explain in one sentence:
② What is the overall trend from July to December?
③ What is the highest temperature, and in which month does it occur?
④ What is the temperature difference between the warmest and coldest months?
The data shows Apr = 55°F and Jun = 75°F. Estimate what May's temperature might be if May was missing from the table. Explain your reasoning.
My estimate for May: _____ °F
Plot the data below on the line graph. Connect the points with a ruler.
| Week | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|---|
| Books Read | 2 | 3 | 3 | 5 | 4 | 6 | 7 | 7 |
① Describe the overall trend for books read over the 8 weeks.
② Which week shows a dip (decrease) compared to the week before? Why might that happen?
③ How many total books were read across all 8 weeks?
Imagine Week 4 was missing from the books data. Using Week 3 (3 books) and Week 5 (4 books), estimate what Week 4 might have been.
My interpolation estimate for Week 4: _____ books
My reasoning:
The data ends at Week 8 (7 books). If the trend continues, predict how many books might be read in Week 10.
My extrapolation prediction for Week 10: _____ books
My reasoning (what pattern did you use?):
🤔 Think About It: Which prediction are you MORE confident in — your Week 4 interpolation or your Week 10 extrapolation? Explain why.
Both the temperature graph and the books graph show trends. Use the sentence frames to compare them.
The highest value is _____ in _____.
The lowest value is _____ in _____.
The overall shape is:
The highest value is _____ in Week _____.
The lowest value is _____ in Week _____.
The overall shape is:
One way the two graphs are similar:
One way the two graphs are different:
Track something in your life for 7 days — steps walked, minutes of reading, or glasses of water. Record your data here:
