Students can use the claim, evidence and reasoning structure to support and explain claims made in math as well. Here students will be given a set of equations and asked if these lines will create a given shape (rectangle, parallelogram, trapezoid and right triangle). Students will then make a claim (either yes or no) and collect evidence to support that claim. Their evidence will include the slope of each line and which lines are parallel and which lines are perpendicular to each other. In the reasoning section students will then explain how the evidence helped them to make their claim. The use of this structure encourages students to think about how they made their claims and express their thinking in writing.
