Every Fun Factor activity is a tangible experience that sparks curiosity and helps students relate to math in real life. Particularly at this unsettled time, our playful activities provide critical emotional connections for students while also providing academic rigor. The activities scaffold to build connections in the brain, and the accompanying teacher guides facilitate differentiated instruction by incorporating standards both below and above grade level.
