Third Grade Curriculum

Third Grade Language Arts

Students understand the basic features of reading. They select letter patterns and know how to translate them into spoken language by using phonics, syllabication, and word parts. They apply this knowledge to achieve fluent oral and silent reading.

  • Know and use complex word families when reading (e.g., -ight) to decode unfamiliar words.
  • Read aloud narrative and expository text fluently and accurately and with appropriate pacing, intonation, and expression.
  • Use knowledge of antonyms, synonyms, homophones, and homographs to determine the meanings of words.
  • Use a dictionary to learn the meaning and other features of unknown words.
  • Use knowledge of prefixes (e.g., un-, re-, pre-, bi-, mis-, dis-) and suffixes (e.g., -er, -est, -ful) to determine the meaning of words.

Reading Comprehension
Students read and understand grade-level-appropriate material. They draw upon a variety of comprehension strategies as needed (e.g., generating and responding to essential questions, making predictions, comparing information from several sources).

  • Use titles, tables of contents, chapter headings, glossaries, and indexes to locate information in text.
  • Ask questions and support answers by connecting prior knowledge with literal information found in, and inferred from, the text.
  • Demonstrate comprehension by identifying answers in the text.
  • Recall major points in the text and make and modify predictions about forthcoming information.
  • Distinguish the main idea and supporting details in expository text.
  • Extract appropriate and significant information from the text, including problems and solutions.

Students write clear and coherent sentences and paragraphs that develop a central idea. Their writing shows they consider the audience and purpose. Students progress through the stages of the writing process (e.g., prewriting, drafting, revising, editing successive versions). Write legibly in cursive or joined italic, allowing margins and correct spacing between letters in a word and words in a sentence. Revise drafts to improve the coherence and logical progression of ideas by using an established rubric.

Writing Applications
Students write compositions that describe and explain familiar objects, events, and experiences. Student writing demonstrates a command of standard American English and the drafting, research, and organizational strategies outlined by teacher. Write descriptions that use concrete sensory details to present and support unified impressions of people, places, things, or experiences. Write personal and formal letters, thank-you notes, and invitations.

Sentence Structure and Grammar

  • Understand and be able to use complete and correct declarative, interrogative, imperative, and exclamatory sentences in writing and speaking.
  • Identify subjects and verbs that are in agreement and identify and use pronouns, adjectives, compound words, and articles correctly in writing and speaking.
  • Identify and use past, present, and future verb tenses properly in writing and speaking.
  • Identify and use subjects and verbs correctly in speaking and writing simple sentences.


  • Punctuate dates, city and state, and titles of books correctly.
  • Use commas in dates, locations, and addresses and for items in a series.

Capitalize geographical names, holidays, historical periods, and special events correctly.


  • Spell correctly one-syllable words that have blends, contractions, compounds, orthographic patterns (e.g., qu, consonant doubling, changing the ending of a word from -y to -ies when forming the plural), and common homophones (e.g., hair-hare).
  • Arrange words in alphabetic order.

Number Sense

  • Count, read, and write whole numbers to 10,000.
  • Compare and order whole numbers to 10,000.
  • Identify the place value for each digit in numbers to 10,000.
  • Round off numbers to 10,000 to the nearest ten, hundred, and thousand.
  • Use expanded notation to represent numbers (e.g., 3,206 = 3,000 + 200 + 6). Find the sum or difference of two whole numbers between 0 and 10,000.
  • Memorize to automaticity the multiplication table for numbers between 1 and 10.
  • Use the inverse relationship of multiplication and division to compute and check results.
  • Solve simple problems involving multiplication of multidigit numbers by one-digit numbers (3,671 x 3 = __).
  • Solve division problems in which a multidigit number is evenly divided by a one-digit number (135 ÷ 5 = __).
  • Understand the special properties of 0 and 1 in multiplication and division.
  • Determine the unit cost when given the total cost and number of units.
  • Compare fractions represented by drawings or concrete materials to show equivalency and to add and subtract simple fractions in context (e.g., 1/2 of a pizza is the same amount as 2/4 of another pizza that is the same size; show that 3/8 is larger than 1/4).
  • Add and subtract simple fractions (e.g., determine that 1/8 + 3/8 is the same as 1/2).
  • Solve problems involving addition, subtraction, multiplication, and division of money amounts in decimal notation and multiply and divide money amounts in decimal notation by using whole-number multipliers and divisors.
  • Know and understand that fractions and decimals are two different representations of the same concept (e.g., 50 cents is 1/2 of a dollar, 75 cents is 3/4 of a dollar).

Algebra and Functions

  • Represent relationships of quantities in the form of mathematical expressions, equations, or inequalities.
  • Solve problems involving numeric equations or inequalities.
  • Select appropriate operational and relational symbols to make an expression true (e.g., if 4 __ 3 = 12, what operational symbol goes in the blank?).
  • Express simple unit conversions in symbolic form (e.g., __ inches = __ feet x 12).
  • Recognize and use the commutative and associative properties of multiplication (e.g., if 5 x 7 = 35, then what is 7 x 5? and if 5 x 7 x 3 = 105, then what is 7 x 3 x 5?).
  • Solve simple problems involving a functional relationship between two quantities (e.g., find the total cost of multiple items given the cost per unit).
  • Extend and recognize a linear pattern by its rules (e.g., the number of legs on a given number of horses may be calculated by counting by 4s or by multiplying the number of horses by 4).

Measurement and Geometry

  • Choose the appropriate tools and units (metric and U.S.) and estimate and measure the length, liquid volume, and weight/mass of given objects.
  • Estimate or determine the area and volume of solid figures by covering them with squares or by counting the number of cubes that would fill them.
  • Find the perimeter of a polygon with integer sides.
  • Carry out simple unit conversions within a system of measurement (e.g., centimeters and meters, hours and minutes).
  • Identify, describe, and classify polygons (including pentagons, hexagons, and octagons).
  • Identify attributes of triangles (e.g., two equal sides for the isosceles triangle, three equal sides for the equilateral triangle, right angle for the right triangle).
  • Identify attributes of quadrilaterals (e.g., parallel sides for the parallelogram, right angles for the rectangle, equal sides and right angles for the square).
  • Identify right angles in geometric figures or in appropriate objects and determine whether other angles are greater or less than a right angle.
  • Identify, describe, and classify common three-dimensional geometric objects (e.g., cube, rectangular solid, sphere, prism, pyramid, cone, cylinder).
  • Identify common solid objects that are the components needed to make a more complex solid object.

Statistics, Data Analysis, and Probability

  • Identify whether common events are certain, likely, unlikely, or improbable.
  • Record the possible outcomes for a simple event (e.g., tossing a coin) and systematically keep track of the outcomes when the event is repeated many times.
  • Summarize and display the results of probability experiments in a clear and organized way (e.g., use a bar graph or a line plot).
  • Use the results of probability experiments to predict future events (e.g., use a line plot to predict the temperature forecast for the next day).

Mathematical Reasoning

  • Analyze problems by identifying relationships, distinguishing relevant from irrelevant information, sequencing and prioritizing information, and observing patterns.
  • Determine when and how to break a problem into simpler parts.
  • Students use strategies, skills, and concepts in finding solutions.
  • Use estimation to verify the reasonableness of calculated results.
  • Apply strategies and results from simpler problems to more complex problems.
  • Use a variety of methods, such as words, numbers, symbols, charts, graphs, tables, diagrams, and models, to explain mathematical reasoning.
