Level 3 Your approach worked (or would work) for solving the problem. Your reasoning, if evident, has no mistakes. (Use of a formula is an approach that worked or would work.) Level 4 Your approach worked, and at least one of the following three aspects of good problem solving is evident: You justified the application of a known formula or rule (for all or part of the problem) OR You made a formula or rule and used it to solve all or part of the problem You verified your solution (in other words, you checked your work). OR CONNECTIONS Level 1 You stopped without including a mathematically relevant observation about your solution Level 2 Level 3 You made a mathematically relevant observation about your solution You identified an underlying mathematical concept or pattern in your solution OR OR You solved the problem, then recreated the problem and found a new solution You related the problem to a similar problem or to a real world phenomenon by expressing the mathematical relationships OR You solved the problem and then used a different mathematical process to solve the same problem. OR You analyzed the relationship among elements in the solution or among similar or different mathematical topics in the solution OR You made and tested a conjecture about the solution, whether or not the conjecture was right OR Level 4 You solved the problem, discovered a general rule about the solution, and demonstrated understanding of the generalization either through explanation of the derivation or through application to more than one other case OR You solved the problem and then extended the solution to a more complicated situation OR You evaluated the reasonableness or the significance of the solution. You identified a formula or rule that worked or would work in solving all or part of that problem SOLUTION Level 1 You didn’t show any work OR No part of the solution is correct OR You showed some work, but the work doesn’t support your answer Level 2 Your solution is right for part of the problem (but not all of it), and there is work to support the correct parts OR Your solution contains errors which lead to an incomplete or incorrect answer Level 3 Your answer is correct, and the work in the solution supports the answer. MATHEMATICAL LANGUAGE (TERMS, VOCABULARY AND SYMBOLIC NOTATION) Communication Criteria Level 1 You didn’t use math language, or if you did, it was just words like “add” and “subtract” You used math language, but not correctly Level 2 Your write-up contains minor flaws. You used a little of the language of: Number sense and numeration, number relationships, number systems and number theory (including fractions and decimals) OR Geometry or measurement Statistics and probability Patterns, functions or algebra Demonstrates understanding of noncomputation language presented in the task. Level 3 Your write-up has no significant flaws and demonstrates understanding through either: 1. Consistent use of quality language beyond that presented in the task, including the language of: Number sense and numeration, number relationships, number systems and number theory, (including fractions and decimals) OR OR Geometry or measurement Statistics and probability Patterns, functions or algebra I used algebra notation with defined variables, or other notation to communicate my solution. OR OR OR OR OR 2. Use of algebraic or other notations MATHEMATICAL REPRESENTATION (GRAPHS, PLOTS, CHARTS , TABLES, MODELS AND DIAGRAMS) Level 1 You didn’t try to make any mathematical representations to solve or communicate an aspect of the solution OR Level 2 You tried to make an appropriate mathematical representation to solve or communicate an aspect of the solution, but the representation lacks labels and/or accuracy. Level 3 You made an appropriate and accurate mathematical representation to solve or communicate an aspect of the solution. You made only inappropriate mathematical representations to solve or communicate an aspect of the solution DOCUMENTATION Level 1 Your write-up contains little or no evidence of how the problem was solved. Facilitator Comments: Level 2 Your write-up contains some clear parts, but there are gaps in how you solved the problem or the reasoning used. Level 3 Your write-up clearly shows how the problem was solved and the reasoning used. This may be evident by some of the following: Results of any necessary computation are present Answers are highlighted Presentation is in logical order Representations are linked to text All parts are connected and labeled.
