These are a review of 3rd grade concepts. This is great for an end of the year 3rd grade review or the beginning of 4th grade for a review to see what your students have grasped. There is a range of concepts from 4-digit place value, 3- and 4-digit addition and subtraction, multiplication/division, time, fractions, and area/perimeter.
I use task cards as whole group. They are put around the room, randomly. The students go around the room answering the cards with their answer sheet on a clipboard. They have a certain amount of time to complete the cards. I check for understanding as they are answering the task cards. We then go over the answers. This gives me a great, quick overview of what the students have learned.
You can also use the task cards in a math center or part of quiz-quiz-trade. Laminate and cute them. I have included a black and white set, in addition to answer sheets if you need fewer cards.
