5 Ways to Use a Hundred Chart

Hundreds Chart

There are many ways to use a hundred chart to help students develop a better understanding of math concepts, along with making connections within and between concepts.

When students see patterns or are able to connect math concepts in different and challenging settings, they truly understand and not just memorized math facts.

In addition to developing a better understanding of math concepts, students develop long term strategies for problem solving.

Five Ways to Use a Hundred Chart

I have come up with five ways to use a hundreds chart:

  • Addition and Subtraction - Use the hundred chart as a number line to do addition and subtraction. Let the students challenge each other or the class to solve number line problems. One example is to add or subtract the fives first by counting up or down and then counting left or right.
  • Multiplication - Look for counting-by multiplication patterns. Colored disks or other small manipulatives work well for marking numbers. Mark the numbers you hit when you count by four. What pattern do they make? Make the counting-by six pattern, or mark the sevens, etc. You may want to print several charts so you can color in the patterns and compare them. Some questions to ask include:
  • Fractions, Percent, Decimals - The hundred chart can be used to convert between fractions, decimals, and percents. “Percent” means “out of 100.” So 30% means “30 out of 100″—which is how much of the whole chart? Some questions to ask include:
  • Factors & Multiples - The first player marks any number on the hundred board. His/her 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.
  • Race to 100 -  Take turns rolling one or two dice and moving that many spaces on the hundreds chart. If you correctly predict your landing place before you move (without counting squares!), then you can go one extra space as a bonus. The first person to reach or pass 100 wins the game.

Math Game - Fraction Face Off

Posted by David Wetzel

Fractions

Fractions

Math games are a great way to help students improve their math facts accuracy. These games can be general math or focus on a specific math concept such as, solving integers.

One math game is called “Fraction Face-Off.” This game can also be modified to address a varied of math concepts.

Math Game

Materials

These materials are for one pair or group of students.

  • 50 - 3×5 note cards (One deck per pair of students)
  • markers
  • scissors
  • Cut 3×5 cards in half
  • Write fractions on each set of cards
  • Shuffle both decks


Procedures

These procedures are for one pair of students.

  • Player 1 and 2 lay down the top 2 cards in their deck - face up
  • Player 1 adds their 2 cards
  • Player 2 does the same
  • Students compare answers and the player with the highest answer keeps all 4 cards (place in a separate pile).
  • Continue playing until all fraction cards are used
  • The player with the most cards wins

Extension Activities

The following are additional strategies for using this math game.

  • Mixed Number Face-Off
  • Multiplication Face-Off
  • Division Face-Off
  • Algebraic Expressions Face-Off
  • Combination Face-Off (using a combination of the above card games)

Connections

The emphasis of this game is on helping students develop a thorough understanding of math concepts, through making connections between math concepts currently being studied and previously studied math concepts.

Resources

The following are additional resources for helping your students develop a greater understanding of math facts.
