Math teaching tools

Math teaching tools for practice and exploration

Use a visual model to make a relationship easier to discuss, then check understanding away from the screen. Multiplication practice, fraction models, clocks and probability experiments serve different purposes. Select one goal and ask students to predict what will happen before changing a condition.

Choose a concept to explore

Multiplication worksheet practice

Choose an available table range and question type that fits the lesson. A short set can reveal which facts need work; a longer sheet is not automatically better practice.

Multiplication practice tool →

Fractions and equivalent amounts

Establish that the whole is divided into equal parts. Compare the amount represented as the numerator or denominator changes. Ask learners to explain why two representations can show the same amount.

Fraction explorer →

Teaching clocks and elapsed time

Compare the hands on an analogue clock with a written time. Extend the activity with times before and after an event, rather than only asking students to name the displayed time.

Probability experiments

Record a prediction before running trials. Compare results across different trial counts and discuss why one outcome is not the same thing as a probability.

The Monty Hall problem

Compare keeping and switching choices over repeated rounds. Focus on the information revealed by the host, then ask students to explain why their first intuition did or did not change.

A 40-minute lesson example

  1. 5 minutes: Invite predictions without showing the result.
  2. 10 minutes: Demonstrate one change at a time on a shared display.
  3. 15 minutes: Let groups compare several cases and record their reasoning.
  4. 7 minutes: Discuss differences and name the mathematical relationship.
  5. 3 minutes: Ask a short question students can answer without the tool.

Before you use the tools

Are all math tools permanently free?

Do not assume that. The directory combines basic practice tools and teaching resources with their own access conditions. Review the current page and plan information.

Can students use a simulation as an answer key?

A simulation helps test a conjecture or compare cases. Ask students to explain the relationship and solve a related problem without the display to check understanding.
