Barker Creek’s Math Manipulatives Activity Kit includes 150 magnetic pieces, 24 reproducible activities, and two magnetic-receptive Kidboards™. Use the 108 magnetic pattern block pieces to teach spatial relationships and simple geometry. The 42 tangram pieces (six tangram puzzles) are a great, hands-on resource for teaching mathematical reasoning and problem-solving skills. Because these math manipulatives are magnetic, your student’s elaborate patterns and puzzles will stay in place! The kit also includes a companion activity book for both sets of math magnets and two of our top-selling magnetic-receptive Kidboards™ – one red and one blue. The magnetic Kidboards™ measure 9″ x 13″ and are sized to fit on children’s laps and desks. This is a fabulous kit for classroom, home and travel! Additional Kidboards™ may be purchased separately.
