Third Grade

The following mathematical concepts and skills are the basis of the second grade Everyday Math 4 curriculum: • Establishing Routines • Addition and Subtraction Fact Strategies • Addition up to 4 Addends • Place Value and Measurement • Telling Time to the Nearest 5 Minutes • Whole Number Operations Number Stories (Addition and Subtraction Algorithms) • Comparison Number Stories and Interpreting Number Stories • Measurement and Data (Inches/Yards and Centimeters/Meters) • Geometry and Arrays • Equal Shares (Fractions) • Open Response Number Problems Nightly Everyday Math 4 Home Link assignments are intended to provide review and practice with concepts and skills learned in class. Second grade students are also expected to practice basic addition and subtraction facts for five minutes each weekday to build math fact fluency. Teachers assess students’ mastery of skills through unit assessments and ongoing assessment of fact fluency in addition and subtraction. Educational technology resources allow students to demonstrate and share their critical thinking with teachers and peers. Students save and curate their individual and group work in their own portfolios.

THIRD GRADE

Third grade students refine mathematical skills in measurement and problem-solving applications as well as in geometry, where they explore more sophisticated symmetry concepts and work with perimeter and area. An introduction of algebraic concepts and reasoning becomes more distinct with activities involving missing addends; missing factors; parentheses; and the recognition of square numbers, attributes, and function rules. More work with grouping further refines multiplication and division concepts in solving real-life problems. Students learn that division is the inverse operation of multiplication and work to develop proficiency with multiplication facts. The following mathematical concepts and skills are the basis of the third grade Everyday Math 4 curriculum: • Math Tools and Time (Bar Graphs) • Multistep Number Stories and Number Models for Two-Step Number Stories • Fractions (Comparing Fractions, Equivalent Fractions, and Fractions in a Number Story) • Multiplication and Division • Multi-digit Multiplication • Operations (Number Sentences with Parentheses and Order of Operations) • Geometry (Area, Perimeter, Line Plots) • Elapsed Time • Measuring to the Nearest ¼ Inch • Open Response Number Problems Because fact fluency is an important skill for learning higher-order math, continued practice with math facts and playing related games at home are strongly encouraged beyond the nightly Everyday Math 4 Home Link. Once students have mastered the concepts of a given operation, they practice several strategies for remembering the related basic facts. Unit tests assess progress and understanding of the concepts studied, and teachers also periodically assess fact fluency.
