Same Denominator Fraction Word Problems Math Games

3 games

In this series of games, your students will learn to solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators. The Same Denominator Fraction Word Problems learning objective — based on CCSS and state standards — delivers improved student engagement and academic performance in your classroom, as demonstrated by research. This learning objective directly references 4.NF.B.3.d as written in the common core national math standards.

Scroll down for a preview of this learning objective’s games and the concepts.

Concepts Covered

Adding and subtracting fractions is similar to whole number computation in that it adds or subtracts two number line quantities. Fractions are a sum of unit fractions. Use visual models to show that unit fractions compose fractions. A mixed number is a whole number plus a fraction smaller than one, written without the addition sign. Use equivalent fractions for mixed numbers by converting the whole into a composition of unit fractions. Add and subtract mixed numbers by using equivalent fractions with the same unit fraction and adding or subtracting the numerators only.

In order to formulate an equation of the form A+B = C for a word problem, the numbers A, B, and C must all refer to the same (or equivalent) wholes or unit amounts. Word problems can be result unknown, total unknown, change unknown, or both addends unknown.

Image for Wave Interference - Waves
Wave Interference - Waves Estimated Duration: 10 minutes Make waves with a dripping faucet, speaker, or laser. Adjust the frequency and amplitude, and observe the changes in the wave. Design experiments to measure wavelength and wave speed. Note: Students will automatically move through this simulation after 10 minutes of playtime.
Image for Wave Interference - Interference
Wave Interference - Interference Estimated Duration: 10 minutes Explore how a pair of wave sources create an interference pattern. Adjust the source frequency and separation, and determine how to change the interference pattern. Identify points of constructive and destructive interference by eye, and by using the detectors. Note: Students will automatically move through this simulation after 10 minutes of playtime.
Image for Wave Interference - Slits
Wave Interference - Slits Estimated Duration: 10 minutes Put up a barrier to see how the waves move through one or two slits, and discover the resulting interference pattern. Determine how to change the pattern by adjusting the slit width and separation. Predict the location of the interference maxima and minima, and verify your predictions. Note: Students will automatically move through this simulation after 10 minutes of playtime.
Image for Basketball Master
Basketball Master Estimated Duration: 12 minutes Shoot a basketball through the hoop and answer some questions along the way! The game does not have any instructional content, it simply has review questions spread throughout.
Image for Waves Intro - Sound
Waves Intro - Sound Estimated Duration: 10 minutes Make sound waves with a speaker, and hear the tone it produces. Adjust the frequency and amplitude, and observe the changes in the wave. Design experiments to measure wavelength and wave speed. Note: Students will automatically move through this simulation after 10 minutes of playtime.
Image for Robot Chef
Robot Chef Estimated Duration: 18 minutes Congratulations, you are creating the first all-robot restaurant in the city! As you serve more customers, you will be able to build more robots to assist in delivering tasty treats. Attend Night School and answer questions to earn advanced robot chefs!
Image for Wavebot
Wavebot Estimated Duration: 16 minutes Join Dr. Camila and Wavebot as they discover the effects of waves on their environment. Play through all 8 levels of this puzzle and compete for the high score!
Image for Earthquake!
Earthquake! Estimated Duration: 20 minutes How good are you at predictions? Can you figure out when—and how powerfully—an earthquake will hit Square City? Triangulation is the key!
