If your students need practice with their addition and subtraction facts within 20, these cards are for you! They can be used as flashcards or task cards and can be used whole group, small group, at a center or even independently. I've included an answer key and recording sheet as well.
Missing addend/minuend cards are far better than traditional flashcards because they require students to use the properties of addition and subtraction during computation.
