Duncan Subtraction Flash Cards

Sobre este produto

Flash cards are a fun way to practice your basic math skills! Buy different packs and shuffle them for an extra challenge. They're color coded so it's easy to sort them. The 52 sturdy cards are double-sided with a math equation from 0-12 on each side (1-0 through 24-12). The answer is in a corner on the reverse side. Cards measure 4.7" x 2.75" and come in a sturdy plastic storage case.
