Calculators are used in every maths and science classroom. Students have to represent and solve problems, including the four operations, calculating areas, volumes and perimeters, using calculators. The use of calculators is part of the mathematics curriculum from year 3 and up. Calculators are not just used to calculate an equation. Especially for younger years, the calculators are used to check if the prediction of the student and the manual calculations they have done were correct. At later stages, you can use the calculator to perform more complex activities and calculations. Ages 6+ years
