The Mortensen Math, also known as Mortensen More Than Math, n’Stuff series includes three n’Stuff booklets;
Animals n’Stuff
Boxes n’Stuff
Transportation n’Stuff
Each booklet provides an enjoyable method for children to learn counting, matching, and relationships, along with addition and subtraction facts. When children place the unit bars over the images in the booklets, they form colourful, tangible illustrations.
