3 1.OA.5 1.OA.4 1.OA.7 1.OA.8 The student demonstrates little to no concept of the connection between addition and subtraction, and is unable to explain her thinking. The student demonstrates a beginning understanding of the connection between addition and subtraction, but does not answer accurately. The student correctly writes two accurate equations using 8, 2, and 10, but is unable to explain her thinking. Or, the student is able to explain her thinking, somehow citing the connection between addition and subtraction, but is unable to write two accurate equations. The student correctly: Writes two accurate addition equations using 8, 2, and 10. Explains her thinking using pictures, numbers, or words, and cites the connection between addition and subtraction in her explanation. 4 1.OA.1 1.OA.3 1.OA.4 1.OA.6 1.OA.7 1.OA.8 1.OA.5 The student shows very little understanding of how to solve the add to with change unknown problem, and cannot write corresponding equations. The student shows a beginning understanding of how to solve the add to with change unknown problem, but lacks reasoning or equation writing skills. The student correctly answers the add to with change unknown problem (4 friends came to play), writes accurate addition and subtraction equations, including those that demonstrate an understanding of the commutative property, but is unable to explain his thinking. Or, the student writes addition and subtraction equations correctly and clearly explains his thinking but does not answer accurately (something other than 4 friends came to play). Or, the student solves the problem (4 friends came to play) and explains thinking clearly but does not write all addition and subtraction sentences accurately. The student clearly: Solves the add to with change unknown problem and determines that 4 friends came to play, and explains his thinking. Writes addition and subtraction equations which correspond to the problem. Applies the commutative property and knowledge of the equal sign to write three additional equations (10 = 6 + 4; 4 + 6 = 10; 10 – 4 = 6; etc.).
