Why it works in the classroom

Real foods

Every card is a fruit, veggie or bean kids see at lunch and at the store.

Real numbers

Younger kids compare grams of fiber. Older kids add them up in Secret Biffie and 100 Grams, which builds math fluency.

Real play

Small groups play Feed Biffie or Fiber War in 10 to 15 minutes, so it fits a center rotation.

Free for teachers

Free lesson library

Science and math lessons built around Biffie, sorted by grade. Each one is ready to print.
