Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the drawn line, they determine an estimate to answer a question about the data.

Instructional Ideas

• Conduct a short lesson on drawing best-fit lines
• Have classmates share their estimates and discuss why their answers may be different

Classroom Considerations

• Class members should be able to plot points on a scaled graph

Pros

• Includes the lines needed to make an estimate

Cons

• None
