Patterning LEVEL “R” LEVEL 1 LEVEL 2 LEVEL 3 LEVEL 4 Below Grade Level Below Grade Level Approaching Grade Level Grade Level Grade Level

PART A: 1, 2, 3

Knowledge and Understanding - knowledge of content; facts, terms, skills, tools) - understanding of concepts - total marks / 10

With help, student demonstrates minimal evidence of understanding basic mathematical concepts. (e.g., 1/10 or 2/10)

With help, demonstrates a partial understanding of most mathematical concepts. There are many errors/omissions. (e.g., 3 or 4/10)

Independently demonstrates some knowledge of mathematical concepts. There are some errors/omissions. (e.g., 5/10 or 6/10)

Demonstrates considerable knowledge of mathematical concepts. There are no major errors or omissions. (e.g., 7/10 or 8/10)

Demonstrates thorough knowledge of content. There are minimal errors or omissions. (e.g, 9/10, or 10/10)

PART B: 4. 5

Problem Solving/Thinking -use of planning skills (understand the problem, make a plan, carry out the plan and look back at solution for reasonableness) - organization of ideas and thinking (clarity, logical organization, using pictures, graphics, numeric or algebraic forms)

Attempts a solution that is unrelated to the problem, or no solution is evident.

Limited evidence of a plan. Solution is incomplete, but attempted. Difficult to understand solution process. (e.g., in question 4, accurately creates one of the patterns when given the rule, and in question 5 student extends the next few figures accurately but does not extend to the 10th figure)

Some evidence of a plan. Needs to look back at solution for reasonableness. Student may not have shown all their thinking. (e.g., in question 4, accurately creates two of the patterns when given the rule, and in question 5 student extends many figures accurately, but information is missing or inaccurate with regard to solving for the 10th figure)

Evidence of a plan. Ideas are mostly organized and expressed using pictures, graphics, tables or numeric/algebraic forms. Most steps in solution are evident. (e.g., in question 4, accurately creates three of the patterns or all four patterns with a few minor errors, and in question 5, student extends required figures accurately using a drawing, numbers, or table of values, but minor errors make solution for the 10th figure incorrect)

Clear evidence of a plan. Ideas and solution are easy to follow. Problem is solved with efficiency and accuracy. All steps in solution are evident.

PART C: 6, 7

Application and Communication - application of knowledge and skills in familiar and new contexts - making conjectures, drawing conclusions, make convincing arguments, justifying, proving and reflecting

Attempts a solution that is unrelated to the problem, or no solution is evident.

Experiences difficulty transferring knowledge to new situations. Explains some simple ideas, but does not provide accurate evidence. (e.g., in question 6 student may identify the pattern core accurately and assign symbols for each method of transportation)

Transfers knowledge to some new situations, but experiences difficulty making connections and convincing arguments. (e.g., in question 6, student identifies pattern core and attempts to extend the pattern to the 31st term; errors in repeating the pattern lead to an incorrect solution; some ideas missing or unclear)

Transfers knowledge to most new situations. Makes convincing arguments and provides some evidence to justify and explain thinking. (e.g., in question 6, student identifies pattern core, and extends it to solve the problem; minor errors may lead to an incorrect solution, but solution is generally logical and clear)

Transfers knowledge to new situations. Makes in-depth inferences, arguments and evidence to justify and explain thinking. (e.g., in questions 6, student shows complete mathematical proof and an accurate answer)
