Calculation Tree, magnetic, 28 pcs., in box

This calculation tree is a magnetic teaching aid made from magnetic film, which is used to create alternative representations of the mathematical operations addition, subtraction, multiplication and division. It sticks e.g. to steel enamel boards or whiteboards. The boxes (number fields) can be labelled using chalks or whiteboard markers to work out the right answer. The bigger the calculation tree, the more challenging the calculation. It is also possible to combine different mathematical operations with each other.

To enable this, the set includes 13 yellow rectangles squares (number fields), which measure approx. 15 x 100 mm, plus 5 yellow circles (operator discs) with a diameter of approx. 100 mm. Also included in the scope of delivery are 10 red arrows, size approx. 50 x 41 mm.

The practical plastic box offers secure storage for the materials and ensures they are always readily to hand.

• for visual representation of arithmetic operations
• for addition, subtraction, multiplication and division
• practical plastic box for transportation and quick access
