Audio:

Do you need a calculator to add or subtract long numbers? Try this!

4529 - 2312 =

You certainly do NOT need a calculator to add or subtract, even if the numbers are really long, like 6846 - 5734 =!

Go through this STEP-BY-STEP activity on Scholastic Study Jams called + and - without Regrouping. (This video requires Flash Player, so if you are having trouble watching, ask your teacher or parent to help you download Flash Player.)

This activity will teach you how to solve addition and subtraction problems without regrouping.

Once you are on the Scholastic Study Jams site, click on the green "Step by Step" circle to begin.

Use the "Show Me" and "Next" buttons to navigate through the steps.

Once you have finished with the first problem, move to the next example by clicking the "Watch Out!" tab.

Keep that window open and come back here for the next part of this lesson.

Great job learning!
