To begin the lesson, display a table such as the following on which data can be recorded.
|Number of People |
|Body Part|| 1 || 2 || 3 || 4 || 5 || 6 |
|Eyes|| || || || || || |
|Toes on 1 Foot|| || || || || || |
|Toes on 2 Feet|| || || || || || |
Ask students to suggest entries for the first row. Then ask how
the numbers in the answers are changing. Repeat with other rows.
Explain that each row shows a number pattern because when you add the
same number over and over, you create a pattern. Tell students you can
use a hundred chart to show how these numbers create patterns.
Access the NCTM E-Example regarding Hundred Boards. Ask a volunteer to enter 2, +, 2,
=, =, =, = into the online calculator and to describe what he or she
sees on the display. Make sure students understand that each time they
press the = sign, the calculator adds 2 to the previous answer. Ask
another student to describe what happened on the hundred chart. Have
students check the numbers displayed on the hundred chart with the
answers from the chart above. Repeat this process for 5 and 10. Ask
students how they would use a calculator to find the pattern for a
Now put the students into pairs. Allow some pairs to continue
exploring patterns online and give each of the other pairs a
calculator, crayons, and a copy of the Hundreds Chart.
Have these students use the calculators to skip count by 3 and then
circle the patterns they find on their paper hundred chart.
Rotate students so that they all get to explore patterns on the computer.
