I created this slideshow/movie/presentation/pdf file to introduce and define arrays to my 2-3rd grade students. There are 52 slides/pages that takes students from guessing the amounts they see by piles, then groups, and the rows. I use real photos of toys, buttons, coins, candy to show different arrays. I also challenge my learners by asking them to come up with all the possible arrays for 16 toy cars.
How can I use this product?
I have showed this to my whole class and then followed it up with a small group activity where I put items on each table and had my learners create as many arrays as they can.
What is included?
1 Quicktime movie with 52 slides that you can click through
or 1 pdf file with 52 pages that you can scroll through each page
