Third Grade Expectations

English Language Arts

In grade three, students will build important reading, writing, speaking, and listening skills. They will think, talk, and write about what they read in a variety of articles, books, and other texts. In their writing, students will pay more attention to organizing information, developing ideas, and supporting these ideas with facts, details, and reasons. Activities in these areas will include:
• Reading a wide range of stories and describing how a story teaches a lesson
• Describing characters in a story and how their actions contributed to events
• Reading texts about history, social studies, or science and answering questions about what they learned
• Referring to information from illustrations such as maps or pictures as well as the words in a text to support their answers
• Learning the rules of spoken and written English
• Learning and using new words, including words related to specific subjects (such as science words)
• Participating in class discussions by listening, asking questions, sharing ideas, and building on the ideas of others
• Giving a class presentation on a topic or telling a story using relevant facts and details and speaking clearly
• Writing stories with dialogue and descriptions of character’s actions, thoughts, and feelings
• Gathering information from books, articles, and online sources to build understanding of a topic
• Writing research or opinion papers over extended periods of time


In grade three, students will continue to build their concept of numbers, developing an understanding of fractions as numbers. They will learn the concepts behind multiplication and division and apply problem-solving skills and strategies for multiplying and dividing numbers up through 100 to solve word problems. Students will also make connections between the concept of the area of a rectangle and multiplication and addition of whole numbers. Activities in these areas will include:
• Understanding and explaining what it means to multiply or divide numbers
• Multiplying all one-digit numbers from memory (knowing their times table)
• Multiplying one-digit numbers by multiples of 10 (such as 20, 30, 40)
• Solving two-step word problems using addition, subtraction, multiplication, and division
• Understanding the concept of area
• Relating the measurement of area to multiplication and division
• Understanding fractions as numbers
• Understanding and identifying a fraction as a number on a number line
• Comparing the size of two fractions
• Expressing whole numbers as fractions and identifying fractions that are equal to whole numbers (for example, recognizing that 3⁄1 and 3 are the same number)
• Measuring weights and volumes and solving word problems involving these measurements
• Representing and interpreting data
