This activity provides students with a first-hand opportunity to experience one of the benefits of the metric system.
Have your partner time how long it takes you to do all four problems in one column.
Time your partner doing the same four problems.
Complete the remaining columns in the same way.
Come to the front table and check each other’s papers after you’ve both finished all four columns.
Column 1: 13x5
Column 2: 13x12
Column 4: 13x10
For each column, record the time (in seconds) it took to complete the column and the number of problems you solved incorrectly.
Which number could you multiply by the fastest?
With which number did you make the fewest mistakes?
Explain what this activity had to do with the metric system.
