A Learning Activity is a strategy a teacher chooses to actively
engage students in learning a concept or skill using a digital tool/resource.

Instruct the students to work through the activity. Students will examine the patterns and count the number of white squares. They will use the number of squares to complete a table. From the table, they will write a formula for the arithmetic sequence.
As the students complete the table, the teacher should monitor students' progress to identify problems or gaps in learning.
Student formulas will be shared with the class. This will allow students to compare their results. It is possible that some students will write explicit formulas and some will write recursive formulas. They will be given the definition for each type of formula and will be asked to identify the type of formula they produced.
This activity will be used before a lesson on finding a pattern from an application and using the pattern to produce either a recursive or explicit formula.
Assessment Strategies:
Student responses will be shared with classmates and will allow them to self-assess their work. Teachers should also check student work using the Desmos Teacher Dashboard and correct any misconceptions or mistakes.
Advanced Preparation:
Prior to the lesson the teacher should:
have an internet connection (WiFi).
have a classroom set of computers, iPads, or smart devices. (If allowed, students can use their devices.)
become familiar with the Engaging Square Patterns Desmos student activity to be prepared to address student questions.
Variation Tips (optional):
Students could work in pairs if there are not enough devices.
The Desmos activity could also be displayed for the entire class and could be worked as a whole group activity.
Notes or Recommendations (optional):
This activity can be used to refresh student knowledge on finding formulas from patterns or tables. Students can work independently or in pairs to find the formulas.
