Alabama 3rd Grade Math Standards

All 26 Alabama math standards for 3rd grade, each explained in plain English. The official wording is in Alabama State Department of Education's document, linked at the end of this page.

26 standards

Operations and Algebraic Thinking

9 standards
3.1
Show a product of two whole numbers as equal groups, naming how many groups and how many in each, and write it as an expression, like 5 groups of 7 is 5 × 7.
3.2
Show and explain a division of whole numbers as either how many are in each equal share or how many equal groups can be made, like 56 ÷ 8.
3.3
Solve multiplication and division word problems within 100 about equal groups, arrays and measurements, using models, drawings and equations with a letter for the unknown.
3.4
Find the missing whole number in a multiplication or division equation with three numbers, like 8 times what number equals 48.
3.5
Learn and use properties such as switching order, regrouping and breaking apart to multiply and divide, like finding 7 × 8 as 7 × 5 plus 7 × 3.
3.6
Write a division as a missing-factor problem using how it relates to multiplication, like solving 32 ÷ 8 by finding what times 8 makes 32.
3.7
Multiply and divide within 100 fluently using properties and patterns, and know every product of two one-digit numbers from memory by the end of third grade.
3.8
Solve and justify two-step word problems with all four operations, write an equation with a letter for the unknown, and check that answers make sense with mental math and rounding.
3.9
Find and explain patterns in arithmetic using properties of operations, like why 4 times any number is always even.

Operations with Numbers: Base Ten

3 standards
3.10
Use place value to round whole numbers to the nearest 10 or 100, like 347 rounds to 350 or to 300.
3.11
Add and subtract within 1000 fluently, choosing from a range of strategies like place value or counting up.
3.12
Multiply a one-digit number by a multiple of 10 from 10 to 90 with materials, pictures and place value, like 6 × 40 as 6 groups of 4 tens.

Operations with Numbers: Fractions

3 standards
3.13
Show that a unit fraction is one equal part of a whole in an area or length model, and that a numerator above 1 counts those parts, like 3/4 is three 1/4 pieces.
3.14
Place fractions as numbers on a number line, splitting 0 to 1 into equal parts for unit fractions and counting those parts off from 0 for others, like 3/4.
3.15
Explain and compare fractions with models and number lines, writing whole numbers as fractions and comparing ones with the same numerator or denominator using <, > or =.

Data Analysis

2 standards
3.16
Make scaled picture and bar graphs for data with several groups, solve one- and two-step how many more or less problems from them, and find a simple probability from a picture.
3.17
Measure lengths with rulers marked in halves and fourths of an inch, and show the measurements on a line plot with matching units.

Measurement

8 standards
3.18
Tell and write time to the nearest minute, and measure and solve add or subtract problems with time spans up to 90 minutes using a number line.
3.19
Estimate and measure liquid volume in liters and mass in grams and kilograms, and solve one-step word problems with any operation in the same metric units.
3.20
Find the area of a rectangle with whole-number sides by covering it with unit squares, leaving no gaps or overlaps, and counting them.
3.21
Find area by counting unit squares, in square centimeters, meters, inches, feet or made-up units like sticky notes.
3.22
Connect area to multiplication through real problems, hands-on materials and reasoning, including splitting a side to use the distributive property, like 4 × 7 = 4 × 5 + 4 × 2.
3.23
Find the area of an L-shaped or other right-angled figure by splitting it into smaller rectangles with hands-on materials and adding their areas.
3.24
Build rectangles that share a perimeter but have different areas, or share an area but have different perimeters.
3.25
Solve real-world perimeter problems for polygons, finding the perimeter from side lengths and finding a missing side of a rectangle.

Geometry

1 standard
3.26
Name and describe shapes with up to 8 sides, including triangles and quadrilaterals, by side count and square corners, and draw examples and non-examples of rhombuses, rectangles and squares.
