Math Teaching Tools
Probability Simulator
Simulate coin flips & dice rolls. Run 1, 10, 100, or 1000 trials and see the law of large numbers in action with live distribution charts.
Fraction Visualizer
Visualize fractions with circle (pizza) and bar models. Compare two fractions side-by-side, see simplified forms, and demonstrate equivalent fractions.
Number Line
Interactive number line for teaching addition and subtraction. Click to add jumps, show operations with arrows, and help students visualize integer operations.
Coordinate Grid
Interactive X/Y coordinate plane. Click to plot points, label them, draw lines between points. Perfect for teaching graphing and coordinate geometry.
Bar Chart Maker
Create instant bar charts from classroom data. Add categories, pick colors, and export as PNG. Great for data collection and visualization activities.
Dice Roller
Roll virtual dice with configurable count and sides (D4-D20). Perfect for probability experiments, math games, and random number generation.
Grade Calculator
Convert points to grades instantly. Supports multiple grading scales (German, US) and shows grade boundaries. Essential for math teachers.
Cube Counting
Generate printable worksheets with 3D isometric cube structures. Students count all cubes including hidden ones. Adjustable difficulty with answer keys.
How to Use Math Tools in Your Classroom
🎲 Probability & Statistics
Use the Probability Simulator to demonstrate the law of large numbers. Have students predict outcomes, then run trials together. Great for teaching theoretical vs experimental probability.
Try this: Students guess how many heads in 100 flips, then watch the results approach 50% as trials increase.
🍕 Fractions Made Visual
The Fraction Visualizer shows fractions as both pizza (circle) and bar models. Students see that 1/2 = 2/4 = 4/8 instead of just memorizing rules.
Try this: Use compare mode to show why 3/4 > 2/3 with visual proof.
➕ Addition & Subtraction
The Number Line makes operations concrete. Students see addition as jumping right and subtraction as jumping left. Perfect for introducing negative numbers too.
Try this: Model word problems like "Start at 5, go back 3" with animated jumps.
📊 Data & Graphing
Collect class data with polls, then use the Bar Chart Maker to visualize results instantly. Students see their data come alive on the projector.
Try this: Survey "How many siblings do you have?" then build the chart together.
