3rd Grade

Math

In a workshop format, students participate in hands-on math activities, games, discussion, and practice. Children solve addition problems with two- and three-digit numbers, and they solve subtraction problems with two-digit numbers. Breaking numbers into hundreds, tens, and ones allows students to further develop their understanding of place value.

This helps children think of multiplication as combining a number of equal groups and division as splitting a quantity equally, guiding them to fluency with multiplication combinations up to 10 x 10 and learning how to represent multiplication and division situations with groups and rectangular arrays.

Third graders use fractions and mixed numbers to solve sharing problems and build wholes from fractional parts. They are introduced to decimal fractions in the context of money, and gain familiarity with decimal equivalents for one-fourth and one-half.

Additionally, students collect, represent, describe, and interpret a variety of data, and create visual representations of their results (charts, tables, graphs).  Through this, they develop a beginning understanding of mathematical rules, functions, and variables.

In geometry, they calculate perimeter, area, and angles, and learn to translate measurements between different measurement systems like inches, feet, and yards.
