- For Class: Algebra 1, Algebra 2
- Topics Covered : Recursion, Sequences, Arithmetic Sequences, Linear Growth, Equations of Lines
- Overview: Fawn Nguyen has curated hundreds of patterns for students to explore. The instructions ask 'What is the equation?' which likely will be interpreted as asking for a closed formula, which is most cases will be the equation of a line. Students will see patterns of growth which gives the instructor an opportunity to talk about slope. These patterns can also be used to talk about recursive formulas and many problems provide multiple ways to approach the pattern.
- Critique: The task of finding the equation is simply stated and students can get to work right away. In the first few minutes, instructors have an opportunity to ask students how they are organizing their discoveries. Prompting students to build a table of values is a good leeson, and the decompostion of each pattern into components gives great opportunites for discussion. The answers are not provided, which is probably good for the student to not have that resource, but the number of objects in the 43rd picture is given, which should give students a method to check if their formula is correct. Many of the patterns are essentially repeats of one another, but there is a lot of variety. On the website, there is little indication to explore recursive formulas or to discuss how to create the next pattern from the previous pattern, but this is another area of exploration that instructors can use.
