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 actually solve math problems. Work through generated problems using a built-in scratch pad—just like working on paper, but without switching apps or losing focus. Practice arithmetic, explore fractions visually, and build algebra skills through interactive activities. Designed for repetition, clarity, visual learning, and confidence. PRACTICE ACTIVITIES Choose a practice card and begin a focused 10-question round. Every card includes a clear preview of the activity. - Addition - Subtraction - Multiplication - Long division - Fraction addition - Fraction subtraction - Fraction multiplication - Decimal practice - Mixed practice Decimal Practice combines addition, subtraction, multiplication, and division in every round. Choose Easy, Medium, or Hard, enter answers using the appropriate decimal separator, and open free technique-based hints when needed. SOLVE THE WAY YOU THINK - Built-in scratch work directly on each problem - Fullscreen scratch mode for more working space - Draw, carry, borrow, and cross out naturally - Pan, zoom, recenter, and clear your scratch work - Familiar worksheet-style problem layouts - Custom keypads for whole numbers, fractions, and decimals Scratch Math is not simply a calculator. It is a focused digital worksheet made for active practice. ALGEBRA PLAYGROUND Build algebra understanding through five interactive activities: - Balance Equations — keep both sides balanced while solving - Expression Tiles — group like terms and simplify expressions - Equation Stepper — choose valid steps and follow the equation - Function Machine — identify rules and complete input-output tables - Coordinate Graph — plot points and turn tables into graphs Algebra activities use generated 10-problem rounds, multiple difficulty levels, visual models, guided explanations, and progress tracking. VISUAL FRACTION PLAYGROUND Explore fractions in a separate hands-on area with animated activity cards and visual models. - 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 Scored fraction activities finish with a clear summary and options to continue practicing or return to the activity hub. LEARN STEP BY STEP - Earn credits by solving problems correctly - Spend credits to unlock complete worked solutions - Use free operation-specific hints during Decimal Practice - Replay explanations with clear, child-friendly steps - Review every answer after each Practice round - See correct, incorrect, and assisted results separately PROGRESS THAT MATTERS - Track solved problems, accuracy, streaks, and perfect rounds - Follow progress across individual Practice modes - Record progress for Fraction and Algebra activities - Unlock badges as skills improve - Earn 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 - Offline-first learning - No account required - Progress stored locally on your device - Reduced Motion support - Responsive layouts for phones and tablets - Language selection for English, Spanish, French, Thai, and Arabic Scratch Math helps students practice, understand, and improve—one problem, one step, and one round at a time.
