Elapsed time task cards ideal for third graders, aligned with Common Core Standards. Great for use in math centers. Can also be used for independent work if finished early or in need of extra practice. Each card contains standard addressed for easy organization. I recommend copy the task cards onto card stock and laminating them. The recording/answer sheet can be copied on regular paper. It should be strongly encouraged that students use a number line to show their work, as this is part of the third grade standard 3MD.A.1. Check out other task cards at Mrs D Grade 3!
