Grade 3 Curriculum

  • English Language Arts

    Third gaders use their reading skills to learn more about many subjects. They read a wide range of genres and describe the characters in the stories and how the story teaches a lesson. They read informational materials (books, articles, online) to learn about history, science and social studies; using information from illustrations like maps and pictures as well as words. They use the Reading and Writing Companion to respond to reading and work on longer papers such as research or opinion pieces. When writing stories, they include conversation and descriptions of the character’s actions, thoughts and feelings.


    Third grade is a big year in the world of learning math. Students not only work with numbers up to 100,000, but they also add and subtract multi-digit numbers, as well as begin to multiply and divide. Third grade is the start of fractions and functions. Students read, write, represent and compare fractions. They start to look at functions in terms of inputs and outputs.
