Texas 3rd Grade Math: What Students Learn

In 3rd grade, Texas students dive into some of the most important math concepts of elementary school. The curriculum follows the Texas Essential Knowledge and Skills (TEKS) and covers five major areas: number and operations, algebraic reasoning, geometry, measurement, and data analysis. StudyPug has a video lesson and practice set for every one of these topics.

Number and Place Value

Students learn to compose and decompose numbers up to 100,000, understand the base-10 place value system through the hundred thousands place, and place numbers on a number line between consecutive multiples of 10, 100, 1,000, and 10,000. They also compare and order whole numbers up to 100,000 using the symbols >, <, and =.

Fractions

3rd grade is when Texas students get a solid introduction to fractions. They represent fractions greater than zero and less than or equal to one with denominators of 2, 3, 4, 6, and 8. They learn what a unit fraction means, compose and decompose fractions, find equivalent fractions, and compare fractions with the same numerator or denominator. Fractions are also represented as distances from zero on a number line.

Addition, Subtraction, and Money

Students solve one-step and two-step problems involving addition and subtraction within 1,000 with fluency. They round to the nearest 10 or 100 to estimate answers and determine the value of a collection of coins and bills.

Multiplication and Division

This is a major focus of 3rd grade TEKS math. Students learn multiplication facts up to 10 by 10 with automaticity and recall the corresponding division facts. They use arrays, strip diagrams, and equations to represent and solve problems, multiply a two-digit number by a one-digit number, and understand division as sharing equally or partitioning into groups.

Algebraic Reasoning

Students describe multiplication as a comparison, find unknown values in multiplication and division equations, and represent real-world relationships using number pairs in a table.

Geometry

  • Classify and sort 2D and 3D figures by their attributes
  • Recognize quadrilaterals including rhombuses, parallelograms, trapezoids, rectangles, and squares
  • Find the area of rectangles using multiplication
  • Decompose composite figures into non-overlapping rectangles to find total area
  • Decompose congruent figures into equal parts and express each part as a unit fraction

Measurement and Data

Students determine perimeter of polygons, solve problems involving time intervals in minutes, choose appropriate units for liquid volume or weight, and summarize data sets using frequency tables, dot plots, pictographs, and bar graphs with scaled intervals.

Personal Financial Literacy

Texas TEKS also includes personal financial literacy for 3rd grade. Students learn about income and human capital, scarcity and cost, planned and unplanned spending, credit and borrowing, saving for goals including college, and decisions involving income, spending, saving, and charitable giving.

Preparing for STAAR Math

Texas administers the STAAR Math assessment in 3rd grade. StudyPug covers every TEKS standard that appears on the test. Each topic includes a video lesson and practice problems so your child can review exactly what they need before test day.
