Number Path

This interactive online number path is helpful for learning cardinality, one-to-one correspondence, addition, and subtraction.

Similar to a number line, a number path is a good stepping stone between counting real-life objects and the number line. Because it uses boxes or blocks, students can still see that one thing is being counted.

To use the interactive online number path, select a color to fill in a box on the bottom of the screen. Then, fill in a box by clicking on it.

Here are some possible ways to use the online number path:

• Fill in each box with a color as you count as a class. After demonstrating this activity, students can do this on their own.
• Model addition problems. Fill in the first addend with one color. Fill in the second addend with a second color. Then count out the answer. Invite students to do this on their own.
• Model subtraction problems. Fill in the minuend with a color. Remove the subtrahend using the color white. Observe and count the answer. Invite students to do this on their own.
