Summary: Simple but fun activities for learning math are arranged by season, with an emphasis on getting outdoors. Measure worms in spring, count clouds in summer, play pick-up sticks in fall, and make snow shapes in winter. Each listing begins with materials needed, which are all either objects that are found outside or simple household items. Explanations of addition, subtraction, multiplication, and division are given at the end. Includes an index of activities, arranged by mathematical concept. 26 pages; grades PreK-3.
Pros: This Swedish import makes learning math fun and healthy. The activities are simple enough for preschoolers to enjoy, but include mathematical concepts that are covered through the primary grades.
Cons: You’d have to live in a four-seasons climate to do everything.
