This is another IPAD center. Again, using a free app, you will get 2 different centers using the same app. The math skills highlighted in this worksheet package include: word form, standard notation, scientific notation, expanded notation, shifts, understanding 1 stands for 1,000,000 on National Parks graphs, & comparing difference. Students will enjoy seeing pictures from National Geographic of parks all across the United States of America. A fun way to work on skills in a more enjoyable setting. Check out my other math centers too.
