One of Mrs. Pepe’s favorite APPS to smash with or just use for student engagement is Geoboard.
“The Geoboard is a tool for exploring a variety of mathematical topics introduced in the elementary and middle grades. Learners stretch bands around pegs to form line segments and polygons and make discoveries about perimeter, area, angles, congruence, fractions, and more.”
