Transcript:How to Make a 100s ChartHi, my name is Bassem Saad. I'm an associate math instructor and a Ph.D. candidate, and I'm here today for About.com to show you how to make a hundreds chart.
Gather Supplies for Your Hundreds Chart
Step one: get a standard eight-and-a-half by 11 inch piece of paper, and a ruler. Make ten rows by drawing 11 horizontal lines, spaced three-fourths of an inch apart. Step two: make 100 boxes by drawing 11 vertical lines, connecting the first horizontal line to the last horizontal line. These 11 lines should be spaced three-fourths of an inch apart.
Begin Filling in the 100s Chart
We can start filling in our hundred boxes by counting the numbers one through 100. In the upper left-hand corner: start counting with one; and along the upper row, fill the next square in with two; the square after that with three; four; five; all the way until you get to ten in the last square. In the next row: begin in the left with the number 11; in the box next to it, record the number 12; next to that, number 13; 14; all the way until you end with 20. Repeat this process until you fill in every box - bottom right-hand corner should be filled with 100. Before using your chart, check it one time to make sure that the numbers are consecutive.
Use the Chart to Teach Counting
So now that you have a completed hundreds chart, we can use the chart to look for patterns. Mark any number ending in five or zero. So that's five, ten, 15, 20, and the last one is 100. So now that we've marked all numbers ending with a five or a zero, we can teach kids how to count by five. For example: five, ten, 15, 20, 25, 30, and so on. Now we know how to make a hundreds chart.
