✍️ CER Claim for Best Method

Using mini whiteboards and their evidence logs, students solve two matched quadratics in more than one way and compare speed, error risk, and simplicity. The teacher models a concise claim-evidence-reasoning paragraph that uses math vocabulary such as factor, zero, equivalent form, and limitation. Students then draft a short written claim naming which method is most efficient for a specific type of quadratic and what evidence would be needed to prove or challenge that claim.
