1. The unit of instruction that I will be evaluating is Numbers Within 20: Addition, Subtraction,
and Data. This concept corresponds to the mathematical domains of Operations & Algebraic
Thinking and Measurement & Data (Common Core State Standards Initiative, n.d.).
• Current Grade: 2nd
• Unit: Numbers Within 20: Addition, Subtraction, and Data
• Standard(s) that correspond to the previous grade (1st):
o (CCSS) 1.OA.B.3 - Understand and apply properties of operations and the
relationship between addition and subtraction. Apply properties of operations as
strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11
is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second
two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12.
(Associative property of addition.) (Common Core State Standards Initiative, n.d.)
o (CCSS) 1.OA.C.5 - Add and subtract within 20. Relate counting to addition and
subtraction (e.g., by counting on 2 to add 2). (Common Core State Standards
Initiative, n.d.)
o (CCSS) 1.OA.C.6 – Add and subtract within 20. Add and subtract within 20,
demonstrating fluency for addition and subtraction within 10. Use strategies such
as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a
number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the
relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one
knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding
