7th Grade Math vs Scratch Math!

"The French mathematician Jacques S. Hadamard found, in a study of 100 leading mathematicians [including Einstein], that the majority of them were primarily visual in their approach." Scientific American, Sept., 1984, p. 56. In seventh grade math the emphasis is on: (1) ratios & proportions, (2) rational and signed numbers, (3) linear equations, (4) scale drawings, area, surface area and volume, and (6) statistical thinking. Math Galaxy’s Seventh Grade Math covers all of the Common Core math standards for seventh grade as listed below. The concepts are presented in bite-size pieces with an unlimited supply of practice problems, with numbers chosen randomly. Illustrations are used throughout to reinforce the concepts. You are guided through problems step-by-step or can just give final answers. Scores can be emailed to be printed. Doing problems earns you robots for the Labyrinth, a maze search game.

Scratch Math is a hands-on learning app built around how students solve math problems. Work through generated problems with a built-in scratch pad, explore fractions visually, and build algebra skills through interactive activities. Practice at your own pace with clear layouts, guided explanations, and room to work things out. Now available in seven languages: English, Spanish, French, Thai, Arabic, Ukrainian, and Farsi (Persian). PRACTICE ACTIVITIES Choose a practice card and begin a focused 10-question round: - Addition - Subtraction - Multiplication - Long division - Fraction addition - Fraction subtraction - Fraction multiplication - Decimal Practice - Mixed whole-number practice Decimal Practice combines addition, subtraction, multiplication, and division in every round. Choose Easy, Medium, or Hard, use the appropriate decimal separator, and open free hints for the current operation. SOLVE THE WAY YOU THINK - Write, carry, borrow, and cross out on the problem - Open fullscreen scratch mode for more working space - Pan, zoom, recenter, and clear your scratch work - Use familiar worksheet-style problem layouts - Enter answers with custom whole-number, fraction, and decimal keypads Scratch Math is a digital worksheet for active practice, with space to work through each question step by step. ALGEBRA PLAYGROUND Build understanding through five interactive activities: - Balance Equations — keep both sides equal while solving for x - Expression Tiles — group like terms and simplify expressions - Equation Stepper — choose valid moves and follow the equation - Function Machine — identify rules and complete input-output tables - Coordinate Graph — plot points and turn tables into graphs Algebra activities offer generated 10-problem rounds, difficulty choices, visual models, guided explanations, saved progress, and activity badges. VISUAL FRACTION PLAYGROUND Explore six hands-on activities: - Explore Fractions — connect fractions, decimals, and percentages - Fraction Bars — compare values and discover equivalents - Build Fraction — create the requested fraction - Fraction Detective — identify fractions shown by visual models - Equivalent Fractions — find values representing the same amount - Fraction Compare — choose less than, equal to, or greater than Explore Fractions and Fraction Bars support free exploration. The four scored activities offer 10-question rounds with feedback, summaries, badges, and replay. LEARN STEP BY STEP - Earn credits by answering Practice problems correctly - Spend credits to unlock worked solutions in Practice and Algebra - Use free operation-specific hints in Decimal Practice - Replay Practice explanations with clear steps - Review answers after each Practice round - See correct, incorrect, and assisted results separately PROGRESS THAT MATTERS - Track solved problems, accuracy, streaks, and perfect rounds - See dashboard progress for Practice categories and scored Fraction and Algebra activities - Unlock badges, including dedicated Decimal, Fraction, and Algebra badges - See newly earned badges at the end of supported rounds - Keep separate progress for up to four local learner profiles BUILT FOR FOCUS - Math activities work offline - No account required - Progress stored locally on your device - Reduced Motion support - Responsive layouts for phones and tablets - Seven languages, with right-to-left layouts for Arabic and Farsi Leaving an unfinished scored activity on mobile restarts it with fresh problems when you return. Completed results and saved progress remain. Scratch Math helps students practice, understand, and improve—one problem, one step, and one round at a time.
