To introduce the concept of patterns and how to extend them, I like to start with a simple AB pattern. We start off the lesson by watching a brief video (there is an ad that will need to be skipped over):
After we watch the video, I use unifix cubes to model AB patterns. As I am modeling, I ask my students to assist me. I build 4-5 different AB patterns with the class using the unifix cubes.
Once I feel the class has a handle on what an AB pattern is; I send them to their seats to build their own AB patterns using the unifix cubes. Here we are practicing:
Students must put their thumb up in the air to indicate they have built an AB pattern for me to view. If students are able to create the pattern, I will then ask them to create an AB ice cream pattern using their cubes (see resources). Here is an example of what this looks like:
