What children learn in Level 20
- Graphs and tables help us answer questions about big numbers. This bar graph's lines count by 10,000s.
- Deer Hollow had 70,000 visitors and Red Rock had 40,000. How many more went to Deer Hollow? 70,000 minus 40,000 is 30,000.
- Good questions are ones the data can answer. This graph can tell us which park was busiest, but not how many visitors came on Monday, because it doesn't show days.
Georgia's K-12 Mathematics Standards:
- 4.MDR.6.2 — Ask questions and answer them based on gathered information, observations, and appropriate graphical displays to solve problems relevant to everyday life.
