The Hundred Chart is a simple tool that parents can use to help their children learn math. There are as many ways to use it as there are numbers on the chart, from teaching simple number recognition to learning addition, subtraction, multiplication and figuring out basic math patterns.

Recently I gave my friend Mellissa a few copies of The Hundred Chart along with a few suggestions for using it with her children’s homeschool math. A few days ago told me that she posted a copy at the breakfast table and now, after a couple weeks, her 6-year-old daughter is counting to 100.

The chart looks like this:

You can make your own Hundred Chart on poster board to hang up in the kitchen or wherever your children do their home work. If you print this post, the entire chart will print out without being partially covered up by the index on the right. Make photocopies of it as is, or enlarge it for posting on the refrigerator. You’ll need many copies for different math activities.

Here are a few ways to use your chart, listed in order of difficulty:

**Easy Math**

After children can accurately count concrete objects like blocks and stones, use the chart to count, first to 10, then 20, and eventually to 100.

Use it to help children recognize numbers. Which is 5? Which is 55?

Make an extra large size copy, cut apart the number sections, and ask your child to make a train on the floor, arranging the numbers in correct order. Start with the numbers 1 to 10, then try 1 to 20. Work up eventually to 100, encouraging your child to wind his number line around furniture or down hallways to make it fit. (You can do the same activity by making numbers by hand on index cards.) Show your child how to sort these number cards by ones, 20’s, etc. This can be an activity all by itself. It also can be used to help children make the number train to 100 without becoming overwhelmed. If they sort the cards, it’s easier to make the train.

What is one more than 7? What is 5 plus 2 more? Count forward to work out simple addition problems on the chart. (You can also do this and many other Hundred Chart activities on a home made number line constructed on adding machine tape.)

What is one less than 8? What is 5 minus 3? Count backward to work out simple subtraction problems.

Take turns with your children doing problems. Give them the easy ones they are ready for, like 3 plus 4. Let them give you hard problems, if they want, like 59 plus 6. Show them how you figure out the hard problems.

**Advanced math**

Use white-out to make three or four number squares blank in each row. At a copy shop, make copies of the chart with blanks and tell your children to fill in the blanks.

Use the chart to count by 10’s, then by 5’s, then by 2’s.

Tell your child to count and color the chart by 3’s. Then post the chart where children can see it from the dining table, and tell everyone to count by 3’s in unison before they can start eating. Do 3’s one week, 4’s the next week, and so on. Counting number groups helps children learn their multiplication tables.

Count by 10’s, but start on the 4 or the 7. Try starting on other numbers.

Count by any size number you can. Start with any number you want.

Count backwards from 100 by 10’s. Count backwards by 5’s or 2’s.

Add 8 to 5. Add 8 to 15, then to 25, then to 35. This makes a bridge from one row of 10 to another. Try other bridging addition problems.

Nine is an interesting number to add because its position is one less than 10. Add 9 to different numbers and try to figure out a rule for adding 9. Then do the same things with 11.

Subtract 5 from 62, then from 52, 42, 32, 22, and 12. Try other subtraction problems with bridging.

Use the hundred chart to figure out hard problems.
