Challenge young math detectives to add and subtract numbers within 100 with this fun, interactive kit. Just place a diecut magnet on the poster to cover one or more numbers. Students use mental-math strategies to determine the covered numbers. A variety of magnetic pieces provide a multitude of lesson opportunities for finding the mystery numbers. The Activity Guide includes supporting reproducibles.
Our poster and magnet sets work best when the laminated poster is secured with medium strength magnets against a magnetically receptive surface. Once the poster is secured at each corner, place the magnetic pieces on the poster as you need them.
