3.NSO-N.2: Represent, compare, and order numbers to 10,000 using various forms, including expanded notation and written out in words.

3.NSO-N.3: Round whole numbers through 10,000 to the nearest 10, 100, and 1,000.

3.NSO-N.4: Recognize sets to which a number may belong (odd numbers, even numbers, and multiples of numbers through 10). Identify the numbers in those classes.

#### 3.NSO-F: Fractions

3.NSO-F.5: Identify and represent fractions (between 0 and 1 with denominators through 10) as parts of unit wholes and parts of a collection.

3.NSO-F.6: Recognize, name, and use equivalent fractions with denominators 2, 3, 4, and 8; place these fractions on the number line; compare and order them and relate the number line to a ruler.

3.NSO-F.7: Know the meaning of 0.75, 0.50, and 0.25 as they relate to money; know that fractions and decimals are two different representations of the same concept.

3.NSO-F.8: Know that any fraction can be written as a sum of unit fractions.

3.NSO-F.9: Model and represent a mixed number (with denominator 2, 3, or 4) as a whole number and a fraction.

#### 3.NSO-C: Computation and Operations

3.NSO-C.10: Demonstrate an understanding of and the ability to use conventional algorithms for the addition and subtraction of up to five-digit whole numbers.

3.NSO-C.11: Add and subtract up to four-digit whole numbers accurately and efficiently.

3.NSO-C.12: Use concrete objects and visual models to add and subtract common fractions (halves, thirds, fourths, sixths, and eighths) with like denominators.

3.NSO-C.15: Know division (÷) as another way of expressing multiplication, i.e., that division is the inverse of multiplication.

3.NSO-C.17: Solve simple problems involving multiplication of multidigit whole numbers by one-digit numbers.

3.NSO-C.18: Solve division problems in which a multidigit whole number is evenly divided by a one-digit number.

3.NSO-C.20: Use the commutative (order) and identity properties of addition and multiplication on whole numbers in computations and problem situations.

#### 3.NSO-E: Estimation

3.NSO-E.23: Estimate the sum and difference of two numbers with three digits (sums up to 1,000) and judge reasonableness of estimates.

3.NSO-E.24: Understand and use the strategies of rounding and regrouping to estimate quantities, measures, and the results of whole-number computations (addition, subtraction, and multiplication) up to two-digit whole numbers and amounts of money to \$100 and to judge the reasonableness of answers.

#### 3.PRA: Patterns, Relations, and Algebra

3.PRA.4: Know and express the relationships among linear units of measure, i.e., unit conversions.

#### 3.G: Geometry

3.G.5: Identify and draw lines of symmetry in two-dimensional shapes.

3.G.6: Apply techniques such as reflections (flips), rotations (turns), and translations (slides) for determining if two shapes are congruent.

3.G.7: Using ordered pairs of whole numbers and/or letters, locate and identify points on a grid.

#### 3.M: Measurement

3.M.1: Demonstrate an understanding of such attributes as length, area, and weight; select the appropriate type of unit for measuring each attribute using both the U.S. customary and metric systems.

3.M.2: Carry out simple unit conversions within a system of measurement such as hours to minutes and cents to dollars.

3.M.3: Identify time to the nearest 5 minutes on analog and digital clocks using a.m. and p.m. Compute elapsed time using a clock (e.g., hours and minutes since ...) and using a calendar (e.g., days since ...).

3.M.4: Estimate and find area and perimeter of a rectangle and triangle using diagrams, models, and grids or by measuring.

#### 3.DASP: Data Analysis, Statistics, and Probability

3.DASP.2: Construct, identify the main idea, and make predictions from various representations of data sets in the forms of tables, bar graphs (horizontal and vertical forms), pictographs, and tallies.

3.DASP.4.: Classify outcomes as certain, likely, unlikely, or impossible.
