Visualpatterns.org is a website that was created in 2013 by Fawn Nguyen, a California math teacher. I have been using these patterns with my 8th graders since I discovered them two years ago. For each pattern, students are given the answer to step 43 and are challenged to find the equation for the pattern. If your students have never studied a visual pattern before, you may want to check out this post by Fawn Nguyen about how she used a visual pattern with a class for the first time.
In the 'Teachers' section of visualpatterns.org, there are suggestions of how to use these patterns with your class. I really like all of the suggestions - but I highly suggest that you check out the link to MathTalks.net in which Fawn shares her students' conversations about these patterns during their regular warm-up routine. I like how her students write equations to match how they see the pattern, thus enabling them to create several different, but equivalent equations for each pattern. For example, here's a conversation her students had about this pattern:
