Classroom observation suggests that it can be difficult for children to master all the addition and subtraction combinations of numbers up to 20. The Quantity Splitting Box will help to make this essential element of arithmetic a pleasant and rewarding experience. Children will find this game a fun and interesting way to practise and memorize simple arithmetic combinations. Contents: The Quantity Splitting Box consists of two stacking boxes made from solid beechwood. The upper box has a sliding panel and a sloping bottom panel with a hole in the center. The lower box is divided into two compartments with a solid bottom panel. In addition, two pieces of felt, one green and one red, fit into the compartments of the lower box. Twenty marbles which are used for the activities and instructions are included.
