912Algebra_SSE_Exponents_Worksheet_Critique

Posted on June 20, 2015August 23, 2015 by

This is a worksheet designed for algebra students developing skills in the rules of exponents. The task works to develop a comprehensive understanding of the rules by asking students to critique samples of student work that address common errors. Students are also asked to think critically about how order of operations might affect the result when simplifying exponential expressions. This worksheet would be best used when students have a strong knowledge of exponents, so that they are able to recognize errors, rather than believe them to be true.

912Algebra_IF_ParPerpLines_Worksheet_Construct_ParallelandPerpendicularMatchingActivity

Posted on June 20, 2015August 2, 2015 by

This activity was used in an Algebra 2 classroom. The objective was for students to demonstrate how to determine if linear functions are parallel or perpendicular. The activity was developed for students to work in groups in a hands-on way while using multiple representations (graphs, equations, tables of values) of linear functions. First, students have to find the slope of each linear function then match them as parallel or perpendicular. This activity also serves as a review of how to find the slope from a graph, an equation and a table of values. Students are then given two specific linear functions and asked to show why they are either parallel, perpendicular or neither. The final task if for students to write a mathematical argument in which they must use the definitions of parallel and perpendicular lines to support their claim using the work they have previously done as their evidence.

912Algebra_REI_LinearEquations_Worksheet_ConstructCritique

Posted on June 20, 2015August 2, 2015 by

This task was used in an Algebra 2 class. The concept was solving linear equations. The objective was for students to write a mathematical argument that demonstrates their understanding of solving linear equations. Students are presented with the work of two students. Students are to write a mathematical argument that includes a claim, warrants, evidence and appropriate use of mechanics.

912Algebra_REI_LinearEquations_Worksheet_ConstructCritique

Posted on June 20, 2015August 23, 2015 by

This task is given to algebra students learning linear equations. Students are given a two-step equation to solve and a sample student’s solution. Argumentation language is used when asking students to explain the sample solution, create a claim, and provide evidence to defend their solution. Sentence starters are used to provoke the use the mathematical and argumentation language.

912Algebra_REI_LinearEquations_Worksheet_ConstructCritique

Posted on June 20, 2015August 23, 2015 by

This task is designed for algebra students to critique two approaches to solving the same linear equation. The common error addressed here is the order in which a student might approach solving an equation. Students are prompted to construct an argument by stating a claim as to which solution he or she agrees with, explaining why that claim is made, and addressing what went wrong in the other solution.

Posted on June 20, 2015August 2, 2015 by

This task was used in an Algebra 2 class. The objective was for students to demonstrate how to solve a two step equation by critiquing the work of another person. Students need to explain the reasoning behind the work shown and determine if it is correct or not. Students then need to make any corrections to the person’s work and provide evidence to support their answers.

This task was presented to students in an Algebra 2 class. The objectives were for students to solve a two step equation and critique the work of others using evidence to defend their answers. It was used at the beginning of the school year when we began to play with the idea of writing mathematical arguments.

912Algebra_CED_LinearFunctions_Worksheet_Construct_Steepness

Posted on June 19, 2015August 2, 2015 by

This activity was used in an Algebra 2 class. It was used at the beginning of the linear functions unit after students learned about slope. Students worked in small groups to determine the steepness of the given segments. The activity was designed with questions that were scaffolded in order to help students dig deeper into their mathematical reasoning. The lesson was also used as a way to get students familiar with showing their “evidence” and supporting their “evidence” with important math ideas, i.e. “warrants”

912Algebra_SSE_ArithmeticSequences_Worksheet_ConstructCritique

Posted on June 19, 2015August 23, 2015 by

Algebra students are asked to use their knowledge of arithmetic and geometric sequences to critique two student answers. Students must identify and agree with a solution and construct an argument using sentence starters. The task then asks students to justify their selection using mathematical language and argumentation and supplies a checklist to remind students to provide a claim, evidence, and warrant.
