Two sets of basic addition fact flashcards: Sums up to 10, and Sums up to 20.
Both sets are available with a patterned background and a solid white background for ink saving purposes and/or printing on colored cardstock.
Each flash card page has the coordinating answer page that, when paired in a two-sided document, provides a two-sided flashcard.
Flash cards make great centers! Try punching a hole in one corner and hanging sets by number or student need on a ring. Allow students to quiz each other or take flash card rings home for practice.
Remember, practice makes perfect!
