Math Tools for Grades 6-8

Ratios, Algebra, Geometry, and Statistics

Each tool targets a specific middle school math standard with visual models, worked examples, and instant feedback.

Ratio & Proportion Visualizer

Explore ratios with tape diagrams, equivalent ratio tables, unit rates, and cross-multiplication proportion solving.

Percent Calculator & Visualizer

Find the part, the percent, the whole, or percent change. 100-grid and bar model visuals with step-by-step math.

Integer Number Line

Add or subtract integers on a visual number line with directional arrows and step-by-step explanations for negative number operations.

Area & Perimeter Explorer

Calculate area and perimeter of rectangles, triangles, parallelograms, trapezoids, and circles with SVG visuals and step-by-step formulas.

Equation Balance Scale

Solve one- and two-step equations visually using a balance scale model. Watch both sides stay equal as you apply inverse operations.

Mean, Median & Mode Explorer

Enter a dataset to see mean, median, and mode on an interactive number line with a balance-point fulcrum, box plot, and calculations.

Factor Tree & GCF/LCM Calculator

Build visual factor trees, find prime factorizations, and compute GCF and LCM with a Venn diagram of shared prime factors.

Angle Relationships Explorer

Visualize complementary, supplementary, and vertical angles, and parallel lines with transversals. Color-coded equal angle pairs.

Math Labs

Investigation Labs for Middle School Math

Guided investigations with data collection tables, lab report panels, and CSV export. Good for small-group work or whole-class instruction.

Ratio, Proportion & Percent Lab

Visualize ratios with bar models, solve proportions using cross-multiplication, and calculate percent change.

Integer Operations & Absolute Value Lab

Visualize integer addition and subtraction on a number line. Discover sign rules for multiplication and division.

Equation Balance & Intro Algebra Lab

Solve linear equations with a visual balance scale. Apply inverse operations step by step and handle variables on both sides.

Fraction Operations & Equivalents Lab

Add, subtract, multiply, and divide fractions with area model and number line visualizations. Find equivalent fractions.

Mean, Median & Mode Lab

Collect data, calculate measures of center, and compare distributions. Explore how outliers shift the mean but not the median.

Angle Relationships Lab

Measure and classify angle pairs. Discover complementary, supplementary, and vertical angle theorems through hands-on investigation.

For Students

  • Use tools as calculators that show their work, step by step.
  • Change values and see how the answer changes to build intuition.
  • Labs let you collect data and write up your findings like a real experiment.
  • No account needed. Come back to a specific problem using a shareable URL.

For Teachers

  • Project tools on a classroom display to model problem-solving strategies.
  • Assign lab URLs for homework or group investigation activities.
  • Tools align to CCSS Math grades 6-8 standards for ratios, expressions, and geometry.
  • No setup. No student accounts. Works on any device with a browser.
