1. Topic Hundreds Chart
2. Definition A hundred chart is a graphic organizer for the numbers 1 100. It contains 10 rows and 10 columns. A hundred chart is a great way to build number sense and help children understand how numbers are related to each other.
3. Objective Grade one students need to be very good in counting from one to one hundred. To teach kids count to one hundred, teachers and parents can use a hundred chart. this chart can be used to explore many other basic math skills such as substractions, multiplication, Factors & Multiples,addition and division. Hundred chart can be used to teach even and odd numbers, skip counting by 5's and 10's and later in grade two or three, this chart can be used to introduce kids with prime and composite numbers. Therefore, Using a hundred chart can help students to develop a better understanding of math. 4. How to make a Hundred Chart A hundred chart use a piece of plywood cut 2 feet x 2 feet. Measure 2-inch by 2-inch rows and columns. This should produce twelve 2x2-inch squares. Since you only want ten squares, use the outside squares as a border. Paint the border. This should leave ten rows and ten columns of 2-inch squares. Use a dark color Sharpie (or other permanent marking pen) to trace the lines you made when measuring. Last, nail a small-headed nail into the top center of each square. The nail will be used to hang the numerals. (See diagram below.) To make the numeral cards, cut 2 x 2-inch squares out of heavy paper. File folders are a good weight. Using thick line markers, write the numerals 1 100 on the squares. Laminate the squares if possible. Use a hole punch to make one hole in the top center of each square. They are now ready to hang on the hundreds chart. Complete one square and fit the numeral card to the hundreds chart before proceeding so that adjustments can be made to insure the best fit before

completing all one hundred and then finding an adjustment is necessary.

6. Things to do with a hundred Chart Addition and Subtraction Use the hundred chart as a number line to do addition and subtraction beyond what your child normally can handle. Take turns making up problems for each other to solve. Develop

mental math skills by showing how to add or subtract the tens first (counting up or down) then the ones (counting left or right.) Find the Number Game To play this 2-person game, you'll need a hundreds chart and two color counters, or squares of paper in two different colors. The child 1 says the name of a number on the chart. Child 2 finds the number and covers it with his color counter. Then they switch roles, with child 2 calling a number for child 1 to find. As they go back and forth, calling and covering numbers, the chart will fill up with two colors of counters. The goal is to be the first to get three of your colored counters in a row. (Players have no control over their own numbers, but they can use strategy to try and keep the other player from getting 3 in a row.) The factors and multiple game The first player marks an even number less than 50 on the hundred board. His opponent marks a factor or multiple of that number. Players alternate, each time marking a factor or multiple of the last number played. The player who marks the last number, leaving his opponent with no move, wins the game. Fractions and Decimals The hundred chart can help you convert between fractions, decimals, and percents. Do you see how? Percent means out of 100. So 30% means 30 out of 100which is how much of the whole chart? If we say that the chart is one whole unit, then how much is each row (in decimal notation)? What size is each box? Can you color 0.47 of the chart? What decimal would mean the same as 1/5 of the chart? And what percent of the chart would that be? Multiplication Look for counting-by (multiplication) patterns. Colored disks are nice for this, or use pinto beans. Mark the numbers you hit when you count by 2. What pattern do they make? Make the counting-by-3 pattern, or mark the 7s, etc. You may want to print several charts so you can color in the patterns and compare them. Why does the counting-by-5 pattern go down the way it does? Why do the 9s move diagonally across the chart?

7. Conclusion Chart is very useful for both teachers and parents to teach their first grade students and children about basic math. Chart is not only help students in studying the numbers, but also help students in playing with numbers and how to operate them. There are so many interactive games we can play by using Hundred Chart.
