## Mathematics In Grade 3, math instruction focuses on the four critical areas below. Teachers primary instruct using small group rotations to meet individual needs based on formative assessments.

Unit 1 and Unit 3 - Addition and Subtraction

Unit 1 focuses on patterns in addition and subtraction facts, the pattern of adding 10s, measuring, and problem solving.

Unit 3 reviews and extends students’ thinking about place value (rounding), multi-digit addition and subtraction, and multi-step problem solving.

Unit 2 and Unit 5 - Multiplication and Division

Unit 2 introduces multiplication by immersing students in a wide variety of multiplicative situations. It invites students to think of the operation in different ways, students make use of a variety of models for multiplication, including equal groups, arrays, the number line, and ratio tables. They also apply the associative and distributive properties to develop efficient, reliable, and generalizable strategies for multiplying.

Unit 5 returns to the study of multiplication, especially as it relates to division. Students again build arrays, but use them to model and solve division as well as multiplication problems. Story problems play a major role, helping students to connect their everyday experiences with division to more formal mathematical concepts.

Unit 4 and Unit 7 - Measurement and Fractions

Unit 4 begins with measurement concepts and skills. Students tell time to the minute and solve elapsed time problems. Students also estimate, measure, and compare the masses of different objects as well as work with volume and solve measurement-related story problems. Unit 4 also introduces students to fractions, using several different models to build, compare, and investigate the relationships among unit and common fractions.

Unit 7 provides a review of the work students previously had with fractions as parts of a whole and distances along a number line, students are introduced to linear and area models that allow them to see fractions as parts of a set as well as a parts of a whole. These models include a ruler, an egg carton, a 12-foot strip of adding machine tape, and a circle graph.

Unit 6 - Geometry

In Unit 6, students develop increasingly precise ways to describe, classify, and make generalizations about two-dimensional shapes, particularly quadrilaterals.
