Indiana 3rd Grade Math Standards

All 24 Indiana math standards for 3rd grade, each explained in plain English. The official wording is in Indiana Department of Education's document, linked at the end of this page.

24 standards

Number Sense

6 standards
3.NS.1
Read and write numbers up to 10,000 and show the same number as a numeral, in words, with models and in expanded form, like 4,026 = 4,000 + 20 + 6.
3.NS.2
Model a unit fraction like 1/4 as one of four equal parts of a whole and 3/4 as three of those parts, with denominators of 2, 3, 4, 6 or 8.
3.NS.3
Place a fraction like 3/4 on a number line by marking equal jumps of 1/4 from 0 and landing on the third mark.
3.NS.4
Use fraction models to show that two fractions can name the same amount with different numbers and sizes of parts, and find simple matches like 1/2 = 2/4.
3.NS.5
Compare two fractions with the same top or bottom number by thinking about the size of the parts, write >, = or <, and back it up with a model, like 1/3 > 1/6.
3.NS.6
Round two- and three-digit numbers to the nearest ten or hundred using place value, like 368 rounds to 370 or 400.

Computation and Algebraic Thinking

8 standards
3.CA.1
Add and subtract multi-digit whole numbers quickly and accurately using place value strategies, number properties and the link between adding and subtracting.
3.CA.2
Solve story problems that add or subtract multi-digit numbers, using drawings or an equation with a letter for the missing number, like 452 + n = 900.
3.CA.3
Show multiplication as equal groups, arrays, area models and equal jumps on a number line, and use objects or drawings to show what multiplying by 0 and 1 does.
3.CA.4
Show division as splitting into equal groups, sharing out equally and undoing multiplication, and use objects or drawings to show how 0 and 1 behave in division.
3.CA.5
Multiply and divide within 100 using fact families and properties of operations, like knowing 6 x 7 = 42 means 42 ÷ 7 = 6.
3.CA.6
Know all multiplication facts and matching division facts from 0 to 10 by heart, like 7 x 8 = 56 and 56 ÷ 8 = 7.
3.CA.7
Solve story problems within 100 about equal groups, arrays or measurements by multiplying or dividing, using drawings or equations with a letter for the unknown.
3.CA.8
Make and continue number patterns within 100, including ones in the addition and multiplication tables, and state the rule, like multiples of 4 always being even.

Geometry

3 standards
3.G.1
Explain that any four-sided shape, including rhombuses, rectangles and squares, is a quadrilateral, and identify and draw shapes that are and are not quadrilaterals.
3.G.2
Name, describe and sketch points, lines and line segments using a ruler, straightedge or technology, and use those terms when talking about flat shapes.
3.G.3
Cut shapes into pieces of equal area and call each piece a unit fraction of the whole, from halves to eighths, like 6 equal pieces each being 1/6.

Measurement

6 standards
3.M.1
Estimate and measure mass in grams and kilograms and liquid volume in quarts, gallons and liters, and solve one-step problems with these amounts using any operation.
3.M.2
Pick fitting units and tools to estimate and measure length to the quarter inch, weight in pounds, and temperature in degrees Fahrenheit and Celsius.
3.M.3
Tell time to the nearest minute and solve word problems about how many minutes pass between two times.
Common Core 3.MD.1
3.M.4
Count any mix of coins and bills, write amounts with ¢ or with $ in dollars and cents, like $6.25, and decide if there is enough money to buy something.
3.M.5
Tile a rectangle with unit squares to find its area and see it equals length times width, and draw rectangles with equal perimeters but different areas, or the reverse.
3.M.6
Find the perimeter of a polygon by adding its side lengths, or work backward to find a missing side when the perimeter is known.

Data Analysis

1 standard
3.DA.1
Collect data from surveys, observations and experiments, show it in scaled bar graphs and picture graphs, and answer real questions by reading and comparing the data.
