BFF Addition and Subtraction : Where Fluency Grows From Understanding.

Flexible Intervention. Powerful Number Sense.

BFF Addition & Subtraction is a powerful intervention kit designed to help students develop flexible strategies for adding and subtracting within 100.

Built on Math Empowered’s Core Four instructional routines, the kit engages students in meaningful mathematical thinking through:

  • Math Talks that spark noticing, estimating, and reasoning

  • Randomizers & Sorts that help students see patterns and connections

  • DARE-ing application problems that build problem-solving confidence.

Thinking Pathways games that reinforce strategies through collaboration.

Students work across multiple representations—including base-ten blocks, number bonds, place value charts, number lines, and equations—so that every strategy connects conceptually.
