Transcript:How to Teach Counting with a 100s Chart

Hi! I’m Samantha Lake for About.com and today I’m going to show you how to teach using a 100s chart. We’re here at Count Me in Math Tutors in Bedford Corners, NY.

The 100s Chart Identifies Patterns

This is a 100’s chart, you can download one online or have your students make their own. Using a 100s chart allows children to use patterns to identify numbers. There are many patterns to use on the hundreds chart we will discuss some of the easiest and best ways to learn how to count. To begin with have students read aloud the numbers in the chart from 1 to 100.

Call attention to the patterns in their voice inflection as their voices rise in each row 47, 48, 49, and drop when they hit the decade number 50. Have students count by 10s from 10 to 100 call attention to the “T” twent T thir T four T. Then have them count by 10s for example 3, 13, 23, 33, and so on. When you get to 23 call attention that every number following will end in a three. Repeat the activity with any number you like. Guide them to notice each time the number of ones stays the same as they read down the columns of numbers and the numbers of 10s increases by 1 each time.

Let Students Draw on the 100s Chart

The patterns students find on the 100s charts can be found in other strands of mathematics. Have them count by 5s. Have them color a red dot on the 100 chart as they say the number. When they finish, there will be two columns of Colored dots the 5s and the 10s. Next have them place a nickel on each number as they say it, this will teach them to count nickels up to $1.00.

Use Mathematical Problems to Find Patterns in the Chart

To challenge your students with the hundred chart, draw a box around any 4 numbers on the chart. Have them add the diagonals and add their sums for example if a student chooses 21,22 31, 32 the sum of the diagonal if it is 21 + 32 = 53 and 22 + 31 also equals 53. Ask students to try it with a couple of examples.These are just a few ideas for you to choose from, you can make up your own creative ways to count with a 100s chart and you will have a lot of fun while teaching.
