Do you have a big decimals test coming up? Or are you studying for your standardized math test? This site is both fun and helpful! On this site you can review the following topics: place values of decimals, how to read decimals, expanded notation for decimals, and how to convert fractions into decimals. On this site you can also review how to add, subtract, multiply, and divide decimals. You will also learn about terminating and repeating decimals.

Students solve decimal multiplication and division problems related to the basic fact 3 × 7 = 21.Students match cards that represent word problems, visual models, and numerical solutions to problems that include the numbers 0.8 and 0.2 for all four operations.Key ConceptsNo new mathematics is introduced in this lesson. Students apply their knowledge about decimal operations.Goals and Learning ObjectivesUse reasoning and mental math to solve problems.Solve word problems involving simple addition, subtraction, multiplication, and division with decimals.

This short video and interactive assessment activity is designed to teach fifth graders about determining the greatest quotient without calculation.

The Decimals Cruncher game will help you learn about decimal operations! You can choose to practice adding, subtracting, multiplying, or dividing. You can also pick how hard the game is. The game has 4 levels: easy, medium, hard, and killer. The Decimals Cruncher will keep track of your score. When you switch to a new operation (addition, subtraction, multiplication, or division), your score will start over again.

Students learn about and practice converting between fractions, decimals and percentages. Using a LEGO® MINDSTORMS® NXT robot and a touch sensor, each group inputs a fraction of its choosing. Team members convert this same fraction into a decimal, and then a percentage via hand calculations, and double check their work using the NXT robot. Then they observe the robot moving forward and record that distance. Students learn that the distance moved is a fraction of the full distance, based on the fraction that they input, so if they input ½, the robot moves half of the original distance. From this, students work backwards to compute the full distance. Groups then compete in a game in which they are challenged to move the robot as close as possible to a target distance by inputting a fraction into the NXT bot.

It is common in the real world to see mathematical examples where the cents sign was used when the dollar sign was supposed to be used. Converting and comparing decimals and fractions can help clear up this misconception. Two real coupons clipped from a Sunday paper coupon section are included in this activity. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.
