This is an 18 card activity designed to introduce the different types of sequences. It includes 6 cards of arithmetic sequences, 6 geometric sequences and 6 that grow in other ways. Cut out and have students find the next number in the pattern and how it grows. Then ask them to classify into 3 different groups. Great way to incorporate the mathematical practices #7 Look for and make use of structure.
and #8 Look for and express regularity in repeated reasoning (Common Core Standards Initiative, 2012).
