4th Grade Math Review: Day 4


In yesterday's post we looked at comparing fractions and fractions and decimals on the number line. For the next few posts, we'll be spending time in the largest reporting category - computations and algebraic relationships. Today we look at the basic operations, addition and subtraction of fractions and decimals.


Adding and Subtracting Fractions

In the fourth grade, adding and subtracting fractions is learned within the context of two fractions that already have the same denominator. Students won't begin adding and subtracting fractions with unlike denominators until the fifth grade. Watch the video to learn more.

Now that you've learned about adding and subtracting fractions, see if you can answer these related problems.

Adding and Subtracting Decimals

Students have been adding for several years now. In the fourth grade, students begin to add decimals to the hundredths place, something that was only learned previously within the context of adding a collection of coins. Watch the video below to learn about addition and subtraction with decimals.

That wasn't so hard, was it? Now that you've learned more about decimal addition and subtraction, try this problem from a released STAAR test.

Correct Answers Here's the video with the answers and explanations. Make sure you've worked them out on your own before watching it.
