Experiment set FRACTIONS
Understanding fractions through experimentation
Using a story about four children of the same age, students work out the rules for fractions in a completely new way with the FRACTIONS experimentation kit. Fractions are represented by colored acrylic glass circle sectors equipped with magnetic plates on the underside. This allows them to be easily arranged or moved on the lid of the storage box. The filled lids can also be lifted for the teacher to check.
The discovery of prime numbers between 2 and 100 using the Sieve of Eratosthenes is also made into an experience with the magnetic plates.
Accompanying materials
Accompanying the FRACTIONS experimentation set are a student workbook and a teacher’s guide with didactic instructions and analog solutions. The student workbook is also available in digital format.
