Alabama 4th Grade Math Standards

All 29 Alabama math standards for 4th 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.

29 standards

Operations and Algebraic Thinking

5 standards
4.1
Explain and write multiplication equations as comparisons, like 35 = 5 × 7 means 35 is 5 times as many as 7.
4.2
Solve times-as-many word problems with drawings and equations that use a symbol for the unknown, like a jacket costing 3 times as much as a $12 hat.
4.3
Solve and justify multi-step word problems, deciding what a remainder means, writing equations with a letter for the unknown and checking answers by estimating and rounding.
4.4
Find all factor pairs of a whole number from 1 to 100, tell whether it is a multiple of a given one-digit number, and decide if it is prime or composite.
4.5
Create and study a number or shape pattern from a given rule, like add 3 starting at 1, noticing the terms switch between odd and even.

Operations with Numbers: Base Ten

7 standards
4.6
Use models and reasoning to explain that a digit in any place is worth ten times what it would be in the place to its right, like 700 versus 70.
4.7
Read and write large whole numbers as numerals, in words and in expanded form, like 4,206 and four thousand two hundred six and 4,000 + 200 + 6.
4.8
Compare two multi-digit numbers by their place values, recording the result with >, = or <, like 45,210 is greater than 45,120.
4.9
Round a multi-digit whole number to any chosen place by thinking about place value, like 36,482 to the nearest thousand is 36,000.
4.10
Add and subtract multi-digit whole numbers fluently with place value strategies, and connect them to the standard algorithm of stacking and regrouping.
4.11
Multiply up to a four-digit number by a one-digit number, and two two-digit numbers, with place value and properties, showing it with equations, arrays and area models.
4.12
Divide numbers up to four digits by one-digit numbers to find quotients and remainders, using place value, properties or multiplication, shown with equations, arrays or area models.

Operations with Numbers: Fractions

7 standards
4.13
Use area and length models to explain why two fractions are equal though their parts differ in number and size, like 1/2 and 2/4, and create equivalent fractions.
4.14
Compare fractions with unlike numerators and denominators by models, benchmarks like 1/2 or common parts, recording >, = or < and justifying, with both from the same whole.
4.15
Break fractions into sums of unit or like fractions in several ways, add and subtract fractions and mixed numbers that share a denominator, and solve related word problems.
4.16
Multiply a whole number by a fraction, seeing 3/4 as 3 × 1/4, and solve word problems with models and equations, like 5 × 2/3.
4.17
Show and explain how tenths and hundredths match, like 3/10 = 30/100, and use this to add them, like 3/10 + 4/100 = 34/100.
4.18
Write tenths and hundredths as decimals and show them with models, like 62/100 as 0.62 or 7/10 as 0.7.
4.19
Compare two decimals to hundredths from the same whole with models and reasoning, recording the result with >, = or < and justifying it, like 0.5 > 0.45.

Data Analysis

1 standard
4.20
Use picture graphs, bar graphs and line plots to solve problems, including making line plots of measurements in halves, fourths and eighths and adding or subtracting from them.

Measurement

6 standards
4.21
Choose a fitting metric, customary or time unit for length, mass, liquid volume or time, and record larger units as smaller ones in a two-column table, like 1 kg = 1,000 g.
4.22
Solve word problems about distance, time, liquid volume, mass and money with all four operations, including fractions, decimals, unit conversions and number line diagrams.
4.23
Use the area and perimeter formulas for rectangles to solve real-world and math problems, like finding the fence length or carpet needed.
4.24
Recognize an angle as a shape made where two rays meet at a shared endpoint.
4.25
Measure angles to the whole degree with a protractor, and sketch angles of a given size, like 35 degrees.
4.26
Split an angle into parts to show its measure equals the sum of the parts, and add or subtract to find unknown angles in diagrams and real problems.

Geometry

3 standards
4.27
Sketch points, lines, segments and rays, right, acute and obtuse angles, and parallel or perpendicular lines, and spot each of them in flat shapes.
4.28
Sort flat shapes by whether they have parallel or perpendicular lines or angles of a given size, and recognize right triangles as their own group.
4.29
Define a line of symmetry as a fold line that splits a flat figure into matching halves, then identify symmetric figures and draw their lines of symmetry.
