Mathematical Practices

8 standards
3.MP.1
Understand what a problem asks and persist through it, like planning the steps of a multiplication word problem and checking that the answer makes sense.
3.MP.2
Turn real situations into numbers and back, like writing 4 × 6 for 4 bags of 6 apples and explaining that 24 is the number of apples in all.
3.MP.3
Build clear arguments and evaluate others' reasoning, like explaining why 1/3 is greater than 1/4 and spotting the mistake in a classmate's work.
3.MP.4
Use math to represent real situations, like drawing an array for rows of chairs or a number line for elapsed time in a school day.
3.MP.5
Choose and use helpful tools, like fraction strips to compare fractions, square tiles to find area, or a ruler marked in quarter inches.
3.MP.6
Calculate and measure carefully and use exact terms and units, like labeling area in square units and perimeter in inches.
3.MP.7
Look for structure in math, like solving 7 × 8 as 7 × 5 plus 7 × 3, or seeing that a rectangle's area is rows times columns.
3.MP.8
Notice repeated reasoning and generalize it, like seeing every product of 5 ends in 0 or 5, or that each new row of an array adds the same amount.

Numerical Reasoning

7 standards
3.NR.1.1
Read and write whole numbers up to 10,000 as standard numerals and in expanded form, like 6,382 = 6,000 + 300 + 80 + 2.
3.NR.1.2
Compare numbers up to 10,000 digit by digit from the largest place, writing the result with >, = or <, like 4,512 < 4,521.
3.NR.1.3
Round whole numbers up to 1000 to the nearest ten or hundred using place value, like 467 rounding to 470 or to 500.
3.NR.4.1
Describe a unit fraction like 1/4 and explain how several copies make another fraction like 3/4, using parts of a whole or set, number lines and area models.
3.NR.4.2
Compare two unit fractions using different tools and methods, like fraction strips showing 1/3 is bigger than 1/6 because its parts are larger.
3.NR.4.3
Show fractions in many ways, including fractions greater than one like 5/4, with models, number lines and drawings.
3.NR.4.4
Spot and write simple equivalent fractions, like 1/2 = 2/4 = 4/8 or 2/3 = 4/6, using models or number lines.

Patterning & Algebraic Reasoning

9 standards
3.PAR.2.1
Add and subtract within 1000 quickly and accurately to solve problems, like finding 642 - 275 or 358 + 467.
3.PAR.2.2
Solve adding and subtracting problems within 10,000 with part-whole methods and place value, write an equation using a letter for the unknown, and justify the answer.
3.PAR.3.1
Describe, continue and make number patterns tied to multiplication, like counting by 4s or the ones digits in the 5s facts, and predict what comes next.
3.PAR.3.2
Show one-digit multiplication and division facts in different ways, like arrays or equal groups, and explain how the two operations are related.
3.PAR.3.3
Use the commutative, associative and distributive properties to multiply and divide within 100, like solving 8 × 7 as 8 × 5 plus 8 × 2.
3.PAR.3.4
Decide whether two expressions with addition, subtraction and multiplication have the same value using what the equal sign means, like 3 × 4 = 6 + 6.
3.PAR.3.5
Multiply a one-digit number by a multiple of 10 from 10 to 90 using place value and properties, like 6 × 40 as 6 × 4 tens, or 24 tens.
3.PAR.3.6
Solve everyday multiplication and division problems within 100 with part-whole methods, pictures or objects, like sharing 36 stickers among 4 friends.
3.PAR.3.7
Solve multiplication and division word problems with whole numbers to 100, write an equation using a letter for the unknown, like 6 × n = 42, and justify it.

Measurement & Data Reasoning

5 standards
3.MDR.5.1
Pose and answer real-world questions with collected data, observations and graphs, like a scaled bar graph of how students get to school.
3.MDR.5.2
Read an analog clock to the exact minute and write the time, and estimate the time to the closest quarter hour, like about 3:45.
3.MDR.5.3
Solve elapsed time problems in hours, half hours and quarter hours, with start and end times on the hour, half or quarter hour within one a.m. or p.m. span.
3.MDR.5.4
Measure lengths with a ruler to the nearest whole, half or quarter inch.
3.MDR.5.5
Estimate and measure liquid volume, length and mass with customary units, solve problems given in one unit, and reason about unit sizes, like a gallon versus a cup.

Geometric & Spatial Reasoning

8 standards
3.GSR.6.1
Identify perpendicular segments, parallel segments and right angles, find them in polygons, and solve problems that involve them.
3.GSR.6.2
Classify and compare polygons by their features, especially quadrilaterals, and find quadrilateral faces on solid figures like cubes and prisms.
3.GSR.6.3
Find lines of symmetry in polygons, like the four lines that fold a square into matching halves.
3.GSR.7.1
Find the area of rectangles in real situations by covering them with same-size unit squares, with no gaps or overlaps, and counting the squares.
3.GSR.7.2
Find the area of rectangles, or shapes made of rectangles, in real problems by tiling them and counting the tiles.
3.GSR.7.3
Discover and explain why multiplying a rectangle's length by its width gives its area, like a 4 by 6 rectangle having 24 square units.
3.GSR.8.1
Find the perimeter of a polygon as the total distance around it and solve problems with perimeters, like fencing around a garden.
3.GSR.8.2
Explore and explain how rectangles can share a perimeter but have different areas, or share an area but have different perimeters.
