What you can do
- Share the set onto plates one by one or all at once, tap plates to select them and read the fraction of the set in the calculation.
- Divide into equal parts or into groups of a given size, with or without a remainder; show fractions and division on a bar with units too.
- In Divisors, try the numbers one by one or all at once to find every divisor and see whether the number is prime or composite.
- Mean, Ratio, Probability and Percentages: even out plates, build groups of red and blue objects, draw from a bag and mark a percentage of a set.
- Choose counters, apples, stars, cubes or candies, hide the result to set a task, and download a PNG with a white or transparent background.
