10 Ways to use the 100 Chart!

June 17, 2017

The 100 chart is easily one of the most useful tools you can have in your classroom! I don’t think I’ve ever seen a class that doesn’t have one displayed either on the wall or on student name tags. They are so versatile! If you’re looking for some fun and creative ways to increase basic numeracy understanding, look no further than the 100 chart! Today I am going to share 10 ways to use the chart to build number sense.

  1. Skip Counting – Give students a printed 100 chart and a set of crayons to practice skip counting. Ask them to identify numbers in the skip counting series by coloring them (count by 3s and color all the numbers in the 3s sequence yellow).
  2. Addition/Subtraction – For students who need tangible tools to see addition and subtraction, a 100 chart is a great option. They can tap numbers with their finger or pencil to show increase and decrease.
  3. Number patterns – Students can look for number patterns in basic or complex equations. Ask students to find 18+6, 28+6, 38+6, etc. What do these have in common?
  4. 10 more/10 less – One of my favorite ways to use a 100 chart is to help students develop the concept of 10 more and 10 less, or 1 more and 1 less. Finding these patterns will help them so much in more advanced math concepts!
  5. Missing Numbers – An added level of difficulty to 10 more/10 less. Give students part of a 100 chart and see if they can fill in the missing boxes based on their knowledge of the 1 more/1 less, 10 more/10 less patterns.
  6. Factors and Multiples – Give students a number and ask them to shade the factors or multiples of that number on the chart. This is a great way to practice multiplication facts!
  7. The Direction Game – Give students directions (written or oral) and see if they can find the secret number on the chart. For example, you could ask students to start at 47 and give them these directions: left, left, up, left, up, right, up. What number do they land on?
  8. Race to 100 – a very popular game in primary classrooms. Students roll dice and move that many spaces on the 100 chart. First to 100 without going over is the winner. They can use 1 or 2 dice. For an extra challenge, have students record the numbers they land on and add them up at the end.
  9. Number Puzzles – cut up a 100 chart however you like and have students piece it together. You can make this activity as easy or as difficult as you like!
  10. Everything Plus Nine – Start at any number on the chart and have the students add 9. Repeat this process a few times then ask students to identify any patterns they see on the chart. Once you have done “plus nine” several times and discussed the pattern, move on to another number (plus 11, plus 5, etc).

There are so many ways you can use the 100 chart to help students develop concrete number sense! I hope these ideas will give you encouragement to dust off that chart and put it to good use in your classroom!
