All 5 sets of 1.MD task cards contains 24 task cards, a recording sheet, and an answer key. That's 120 task cards in all, along with 5 answer keys!
1.MD I use these task cards with my kids after I introduce the concept. When students are working on math by themselves (during a concept that is a version of daily 5 for math), they can work through these task cards. You can also set them up around the room and have students move through the task cards.
