The maths booklet helps children learn to write numbers in primary school. This booklet contains 20 highly chequered sheets, each with 10 vertical and 10 horizontal boxes in 15 x 20 mm format. The indented colour border shows the children the beginning and end of the line and provides space for notes. The rounded corners prevent annoying dog-ears and keep the school bag tidy and organised. The coloured background of the spaces helps children to orientate themselves and prevents them from slipping around in the lines. Both the writing paper and the entire cover are made from Pure Impact recycled paper (without optical brighteners and without chlorine bleach), which is made entirely from recycled fibres and is therefore 100 % recyclable. The magazine has therefore been awarded the "Blue Angel" and "Austrian Ecolabel" quality seals.
