Mystery Numbers: Using Variables in Equations

Students analyse an algebraic equation to find the mystery numbers represented by variables. The student will justify steps used to reach conclusions through computations and "math talks". Justifications can include the use of concrete objects, pictorial representations, and the properties of umbers and operations.

Mystery Numbers: Variables
	Level 1 (N/A)	Level 2 (N/A)	Level 3 (N/A)	Level 4 (N/A)
Organization	Level 1 Information related to investigation is not organized.	Level 2 Information related to investigation is somewhat organized.	Level 3 Information related to investigation is well organized.	Level 4 Information is very well organized with clear explanations.
Completeness	Level 1 Large pieces of information are missing -- the investigation is not complete.	Level 2 Some pieces of information are missing -- the project is mostly complete.	Level 3 No large pieces of information are missing, but some explanations may be lacking or some work may not be shown.	Level 4 The project is complete, all information is present with details and all work is shown.
Accuracy	Level 1 Math work is incorrect and demonstrates lack of understanding of concepts. Involvement in math conversations is absent or not relevant to task.	Level 2 Math is incorrect in several places and demonstrates incomplete understanding of concepts. Involvement in math conversations is limited.	Level 3 Math work is correct but may contain some computational errors. Involvement in math conversations is useful for task completion.	Level 4 Math work is accurate, and demonstrates thorough understanding of concepts. Involvement in math conversations is consistent and integral to task completion.
Equation Consolodation	Level 1 Equation created for class consolidation is incomplete or incorrect. An understanding of relevant math processes is not apparent.	Level 2 Equation created for class consolidation is incomplete or incorrect in some areas. An understanding of relevant math processes is somewhat apparent.	Level 3 Equation created for class consolidation is complete in almost all areas. An understanding of relevant math processes is readily apparent.	Level 4 Equation created for class consolidation is complete in all areas. An understanding of relevant math processes is consistently apparent.
Working Efficiently	Level 1 Student did not use time efficiently, was distracting to others, and did not contribute significantly to the completion of task.	Level 2 Student needed considerable help to stay on task, was unfocused and distracting, and inconsistently helped complete task.	Level 3 Student needed little help to stay on task, was focused most of the time, and finished most of the assigned task.	Level 4 Student worked independently, diligently, and needed few prompts to stay on task. Student finished assigned task successfully.
