Three pillars that guide every lesson, activity, and assessment.
Third grade is the pivotal year when children move from learning to read into reading to learn. Our curriculum supports that shift through rich literature, informational text, and content-area reading across every subject.
Children begin to think in multiplicative terms — equal groups, arrays, fractions as numbers, and area as multiplication. Hands-on models, fact fluency practice, and real-world problems anchor every concept.
Every lesson aligns to CCSS Math, CCSS ELA, the Next Generation Science Standards*, and the C3 Social Studies Framework. Visit Your State to see what your state adds or places differently.
The Third Grade Shift
Third grade is when learning becomes more abstract, more independent, and more analytical. Our curriculum is built to scaffold these four shifts so the year feels like growth, not a leap.
Children move from adding/subtracting within 100 to fluently multiplying and dividing within 100, plus adding/subtracting within 1,000. Equal groups, arrays, and area become the new mental models.
With the mechanics of reading mostly automatic, students use texts as tools — extracting main ideas, citing evidence, comparing sources, and building knowledge across subjects.
Children shift from isolated sentences to paragraphs with topic sentences, supporting details, linking words, and conclusions across opinion, informative, and narrative writing.
In science and social studies, students move beyond describing what they see to explaining cause-and-effect relationships, drawing on evidence to support claims.
