A Progression Toward Mastery Assessment Task Item STEP 1 Little evidence of reasoning without a correct answer. (1 Point) STEP 2 Evidence of some reasoning without a correct answer. (2 Points) STEP 3 Evidence of some reasoning with a correct answer or evidence of solid reasoning with an incorrect answer. (3 Points) STEP 4 Evidence of solid reasoning with a correct answer. (4 Points) 1 1.OA.1 1.OA.4 1.OA.6 1.OA.8 The student demonstrates a limited ability to both explain his thinking and answer accurately. The student demonstrates a beginning concept of how to solve an addend unknown relationship problem using pictures, words, or numbers by attempting to show her thinking, but provides an inaccurate answer. The student correctly solves the addend unknown relationship problem and writes a corresponding equation, but cannot explain his thinking in pictures, words, or numbers. Or, the student explains her thinking using pictures, words, or numbers, but is unable to write an accurate equation. The student correctly: Solves the addend unknown relationship problem and determines that 7 ducks are babies. Explains thinking by drawing a picture, writing numbers or equations, or words. Writes an equation that corresponds with her solution process (addition or subtraction). 2 1.OA.4 1.OA.5 1.OA.7 1.OA.8 The student shows little evidence of understanding how addition and subtraction differ, or is unable to complete the task. The student shows evidence of beginning to understand how addition and subtraction differ through his explanation, but demonstrates incomplete reasoning and/or an incorrect answer. The student identifies that Jennifer is incorrect, but cannot fully support the claim or explain his thinking clearly. The student correctly identifies that Jennifer is correct that addition can be used to solve a subtraction problem, and that she is incorrect in adding 9 and 6 to solve 9 – 6. The student shows her thinking using words, pictures, or numbers.
