*Learning Goal: Build procedural fluency with writing and graphing exponential functions.*

# Classwork:

# Standards:

**Common Core**- HSF.LE.A.2 – Construct linear and exponential functions, including arithmetic and geometric sequences, given a graph, a description of a relationship, or two input-output pairs (include reading these from a table).

**TEKS (2015-16)**- A.9(C) – write exponential functions in the form f(x) = abx (where b is a rational number) to describe problems arising from mathematical and real-world situations, including growth and decay
- A.9(D) – graph exponential functions that model growth and decay and identify key features, including y-intercept and asymptote, in mathematical and real-world problems

Thank you for sharing! I am planning on trying this with my Algebra classes tomorrow but I modified it as a Desmos activity. There are some drawbacks to doing it this way, but I like that I have the ability to project how a group sorted a set so we can have conversations as they work. I’m not as concerned about creating the missing graph by hand as they are already strong with that skill. Here’s a link to the activity if you want to try it or have suggestions on how to make it better. http://tinyurl.com/hk2xm3n

This is great, Mary! I really like it and would love to hear how it goes with your students. Great work!

One thing I’ve seen from another Desmos card sort that I liked is having a screen that asks for students to explain their thinking on a specific card. Here is a link to an example. Your activity looks great though! Thanks for sharing!
