GAME INSTRUCTIONS
What is the objective of the game?
The game FRACTION FACTORY: Adding and Subtracting Fractions with Different Denominators consists of assisting a factory robot through a three-step assembly line to solve fraction addition and subtraction equations. The main goal is to correctly compute operations with unlike denominators by finding the least common multiple (LCM), converting to equivalent numerators, and solving the final sum or difference.Recommended age and educational level
Recommended age: 10 to 11 years and up (Upper Elementary and Middle School, Grades 5 and 6+). This age group is targeted because it requires prior knowledge of basic fraction concepts, multiples, LCM, and arithmetic operations (multiplication and division). It is an ideal resource for students learning or reinforcing fraction operations, teachers, parents, and tutors guiding learners through step-by-step math strategies, and adults looking to refresh arithmetic skills.How to play: single player or multiplayer
Game mode: single player. The user plays individually, progressing through the factory line as correct answers are submitted. It can also be utilized as a cooperative classroom activity, where student pairs collaborate to calculate the LCM and equivalent numerators before inputting their choice.What do you learn with this game? Learning outcomes and skills
This educational game directly aligns with Mathematics standards and builds key skills:- Unlike denominator operations: mastering the step-by-step algorithm for adding and subtracting fractions.
- Least Common Multiple (LCM): identifying the smallest common denominator among options.
- Equivalent fractions: converting numerators proportionally using division and multiplication rules.
- Sequential problem-solving: breaking down complex multi-step math problems into structured tasks.
Tips to get the most out of this game
Unplugged activity suggestion: Since the game intentionally leaves out fraction simplification to emphasize the core algorithm, implement an offline simplification worksheet. Have students record their game outputs on paper and reduce final answers to their simplest form (e.g., converting 3/12 to 1/4).Video
