3rd Grade Mathematics

Through Bridges in Mathematics, students in 3rd grade become confident with math facts and work daily on spiraling skills. Through the frequent use of base-10 and base-5 blocks, mats, tangrams, patterns, and more, they develop facility with manipulating ever-larger numbers with different types of operations. As in previous grades, games have children identifying and predicting patterns. In teacher-led groups, students also explain their work to each other, emphasizing the thinking process and learning multiple strategies to solve problems. In the second semester, students delve into a first-time look at fractions to compare, rate, order, and identify fractional parts. Students also focus on mastery of multi-digit addition and subtraction problems with regrouping. They continue to focus on multiplication and division fact fluency as they begin to learn how to solve multiplication and division number stories. Students also spend time working on a basic geometry unit that includes area and perimeter word problems, practice computational fluency with basic addition, subtraction, multiplication, and division facts, and read, write, and compare numbers up to 10,000.
