I wrote this 22-question circuit to help my algebra one students (though algebra two and college algebra students would gain a lot from this circuit) learn the patterning and notation that surrounds the arithmetic sequence. Too often, students (and teachers) are thrown into generalizations before seeing enough examples. This circuit aims to help them discover and uncover the salient characteristics (first term, common difference) and associated variables / equations with arithmetic sequences.
There is no answer key provided because the answers are imbedded in the circuit (it is how the students move from one question to the nest). The only thing the teacher needs to do is work the circuit ahead of the students to decide how and when to best use it in his or her classroom.
My colleagues and I check our circuits very carefully but should you ever suspect an error or get stuck, please don't hesitate to email me at email@example.com.
