Interactive mathematical tools and practice modules for students.
A spatial geometry tool for exploring similar right triangles and altitude relationships. Connect corresponding sides with virtual colored wires, enter similarity statements, and watch dynamic 2D animations glide and rotate the triangles into side-by-side alignment.
Launch Rotate & Relate →A high school geometry mastery tool with a 3-stage gated learning loop: name the angles with geometric notation, identify their angle pair relationship, and solve the algebraic equation. Features dynamic SVG diagrams and session performance reports.
Launch Angle Detective →An arcade-style radar defense game where students practice plotting polar coordinates \((r, \theta)\) and radians to neutralize incoming threats before shields breach. Features tiered difficulty, negative radius targets, call sign privacy, and retro audio.
Launch Polar Defender →An inferential statistics suite for Chi-Square variance, 1-Sample T-tests, Z-tests for means, and Z-tests for proportions. Dynamically renders distribution curves, shades critical rejection regions \((\alpha)\), computes test statistics, and reports exact p-values in real time.
Launch Statistics Calculator →An interactive chemistry tool for mastering oxidation numbers, electron transfer, and redox pathways. Assign oxidation states with real-time rule validation, distinguish oxidizing and reducing agents (OIL RIG), and access guided arithmetic hints.
Launch Redox Explorer →A concrete mathematical manipulative that models quadratic equations \(ax^2 \pm bx = c\) as woven patterned rugs. Students visually guess and refine unknown rug dimensions with animated algebraic substitution, interval feedback arrows, and scaffolded discriminant cases.
Launch The Rug Problem →A point-and-click grading assistant that turns rubric selections and common comments into warm, cohesive feedback paragraphs with automatic score summaries and one-touch clipboard export.
Launch FeedbackFlow →A collaborative team vocabulary board game inspired by Codenames. Paste any word list to generate randomized 4×4 grids with animated card reveals, secret Spymaster key generation, and an independent teacher answer key tab.
Launch Vocabulary Codenames →Explore 13 interactive classroom tools including the Spin-a-Name Wheel, Fraction Visualizer, Transversal Angle explorer, and Polar Defender math game.
Explore Tools in Presentation →Dedicated student tools will be added directly into this directory for upcoming units (algebraic reasoning, coordinate graphing, and geometric transformations). Check back as each unit begins!
