Indiana 4th Grade Math Standards

All 25 Indiana math standards for 4th grade, each explained in plain English. The official wording is in Indiana Department of Education's document, linked at the end of this page.

25 standards

Number Sense

7 standards
4.NS.1
Read and write numbers up to 1,000,000 as numerals, in words, in expanded form and with models, like 305,120 = 300,000 + 5,000 + 100 + 20.
4.NS.2
Use number lines and area models to show mixed numbers and improper fractions, like 1 3/4 = 7/4, and show that a whole number can be written as a fraction, like 3 = 6/2.
4.NS.3
Use fraction models to explain why two fractions with different numbers and sizes of parts can be equal, and create equivalent ones like 3/5 = 6/10 = 60/100.
4.NS.4
Compare fractions with unlike numerators and denominators using common denominators or benchmarks like 1/2, record with >, = or <, and explain why the wholes must match.
4.NS.5
Write tenths and hundredths as decimals and fractions, show decimals in words, models and expanded form, and know halves and fourths as decimals, like 3/4 = 0.75.
4.NS.6
Compare two decimals to the hundredths by reasoning about their size, record with >, = or <, and justify it with a model, like 0.7 > 0.65.
4.NS.7
Round multi-digit whole numbers to any place using place value, like 47,382 rounded to the nearest thousand is 47,000.

Computation and Algebraic Thinking

9 standards
4.CA.1
Multiply numbers up to four digits by one digit and two-digit numbers by two-digit numbers, like 23 x 47, using place value strategies, and explain the method.
4.CA.2
Divide numbers up to four digits by a one-digit number to find the quotient and remainder, like 1,234 ÷ 5, using place value and multiplication, and explain the method.
4.CA.3
Show that order and grouping do not change a product, so factors can be multiplied in any order, and explore and use the distributive property, like 6 x 14 = 60 + 24.
4.CA.4
Explore how factors and multiples relate for numbers 1 to 100 and list them for a given number, like 1, 2, 3, 4, 6, 8, 12 and 24 as the factors of 24.
4.CA.5
Solve times-as-many story problems, like 3 times as tall, with drawings or equations, and tell them apart from how-many-more problems, with no remainders.
4.CA.6
Add and subtract fractions with the same denominator using fraction models, and break a fraction into unit fractions, like 3/5 = 1/5 + 1/5 + 1/5.
4.CA.7
Add and subtract mixed numbers with like denominators, for example by rewriting them as improper fractions, like 2 1/4 + 1 3/4 = 4.
4.CA.8
Solve story problems that add or subtract fractions of the same whole with like denominators, using fraction models and equations, like 3/8 of a pizza plus 2/8 more.
4.CA.9
Spot the rule that links pairs of numbers and use it to get the output from any input, like times 4, and build number patterns from a given rule.

Geometry

3 standards
4.G.1
Recognize, describe and sketch parallelograms, rhombuses and trapezoids, using a ruler, straightedge or technology to draw them accurately.
4.G.2
Name, describe and draw rays, right, acute and obtuse angles, and parallel and perpendicular lines with tools, and find them inside flat shapes.
4.G.3
Sort triangles and quadrilaterals by whether they have parallel or perpendicular sides or right, acute or obtuse angles, like a right triangle.

Measurement

4 standards
4.M.1
Use a ruler to measure objects to the closest quarter inch, eighth inch or millimeter.
4.M.2
Convert larger units to smaller ones in the same system, like kilometers to meters, pounds to ounces or hours to minutes, and use this in real problems.
4.M.3
Use all four operations to solve real problems about distance, time, volume, mass and money, including simple fraction sums and changing larger units into smaller ones.
4.M.4
Use area and perimeter formulas for rectangles to solve problems, and find the area of shapes made of rectangles by splitting them apart and adding the pieces.

Data Analysis

2 standards
4.DA.1
Ask questions data can answer, then collect and graph the data in line plots, bar graphs and frequency tables, and solve real problems by interpreting it.
4.DA.2
Make a line plot of measurements in halves, quarters and eighths of a unit, and add and subtract fractions using it, like the total length of the three shortest ribbons.
