What Is a Hundreds Chart?
A hundreds chart is organized with numbers one through one hundred in columns and rows. When you read a hundreds chart, you read it like a book, from left to right, starting from the top. This visual tool helps us see how numbers increase and assists with adding numbers.
Here are the steps to tackle addition using a hundreds chart:
| Step # | Action |
|---|---|
| 1 | Find the larger addend, or number, on the chart. |
| 2 | Count up the second addend or number. |
| 3 | The number you land on is the sum, or answer. |
| 4 | Check your answer to ensure it makes sense with the problem. |
Let's practice understanding this method with a few examples.
