-
2.NSO-N.6
Identify the value of all U.S. coins and $1, $5, $10, and $20 bills. Find the value of a collection of coins and dollar bills and different ways to represent an amount of money up to $5.
-
2.NSO-F
Fractions
-
2.NSO-F.7
Know that fractions may represent a portion of a whole that has been partitioned into parts of equal area or length; use the terms "numerator" and "denominator."
-
2.NSO-F.8
Recognize the inverse relationship between the size of a unit fraction and the size of the denominator.
-
2.NSO-F.9
Recognize, name, and write commonly used fractions such as 1/2, 2/3, and 3/4.
-
2.NSO-F.10
Recognize that fractions such as 2/2, 3/3, 4/4, 10/10, and 100/100 are equal to the whole and to one.
-
2.NSO-C
Computation and Operations
-
2.NSO-C.11
Demonstrate the ability to use conventional algorithms for addition (two three-digit whole numbers and three two-digit whole numbers) and subtraction (two three-digit whole numbers).
-
2.NSO-C.12
Find the distance between numbers on the number line.
-
2.NSO-C.13
Know addition and subtraction facts (addends to 12), commit to memory, and use them to solve problems. Select and use appropriate operations (addition and subtraction) to solve problems, including those involving money.
-
2.NSO-C.14
Demonstrate the ability to add and subtract three-digit whole numbers accurately and efficiently.
-
2.NSO-C.15
Use mental arithmetic to find the sum or difference of two two-digit numbers.
-
2.NSO-C.16
Represent multiplication as repeated addition. Example: 2 + 2 + 2 +2 = 8, so 4 x 2 = 8 or "4 groups of 2s."
-
2.NSO-C.17
Demonstrate proficiency with multiplication facts for the ones, twos, and fives.
-
2.NSO-C.18
Demonstrate an understanding of the inverse relationship of addition and subtraction, and use that understanding to simplify computation and check solutions.
-
2.NSO-C.19
Know and identify various meanings of addition and subtraction, such as combination (i.e., plus, combined with, more), subtraction as comparison (i.e., how much less, how much more), equalizing (i.e., how many more are needed to make these equal), and separation (i.e., how much remaining).
-
2.NSO-E
Estimation
-
2.NSO-E.20
Estimate, calculate, and solve problems involving addition and subtraction of two-digit numbers. Describe differences between estimates and actual calculations.

-
2.PRA.4
Construct and solve open sentences with variables for addition and subtraction of up to two three-digit numbers.
-
2.PRA.5
Use the commutative and associative rules for addition to simplify mental calculations and to check results.

Classify familiar two- and three-dimensional shapes by common attributes such as shape of curved and straight lines, number and shape of faces, edges, and vertices.
-
2.G.3
Match and construct congruent and symmetric shapes.
-
2.G.4
Identify shapes under rotation (turns), reflections (flips), translation (slides), and enlargement. Describe direction of translations (e.g., left, right, up, down).
-
2.G.5
Predict and explain the results of putting two-dimensional shapes together and taking them apart.
-
2.G.6
Relate geometric ideas to numbers (e.g., seeing rows in an array as a model of repeated addition).
