# Fourth Grade Math

### Fourth Grade Math Overview

In fourth grade math, students take the foundational knowledge of place value, fractions, and algebraic concepts they developed during their third grade year and build upon them, while also continuing to build their skills in the areas of geometry, measurement, and data.

**In numbers and operations (base ten),**students will expand their understanding of place value by generalizing place value understanding for multi-digit whole numbers (M04.A-T.1; CC.2.1.4.B.1). They will then take this knowledge of place value and their understanding of the properties of operations to complete multi-digit arithmetic (M04.A-T.2; CC.2.1.4.B.2).

**In numbers and operations (fractions),**students will extend their knowledge of fractions to include fraction equivalence and ordering (M04.A-F.1; CC.2.1.4.C.1). They will also be working on applying their previous understanding of operations on whole numbers in order to build fractions from unit fractions (M04.A-F.2;CC.2.1.4.C.2). Additionally, students will be working on decimal notation and comparing decimal fractions (M04.A-F.3; CC.2.1.4.C.3).

**In algebraic concepts,**students will be using all four operations to solve problems involving whole numbers (M04.B-O.1; CC.2.2.4.A.1). In developing greater fluency with their multiplication skills, students will also be focusing on factors and multiples (M04.B-O.2; CC.2.2.4.A.2) and work to generate and analyze patterns (M04.B-O.3; CC.2.2.4.A.4).

**In geometry,**the student focus will be on drawing and identifying lines and angles, and on working to classify shapes by properties of their lines and angles (M04.C-G.1; CC.2.3.4.A.1; CC.2.3.4.A.12; CC.2.3.4.A.13).

**In data analysis and probability,**students will be working on concerting measurements from a larger unit to a smaller one and on solving problems that involve the use of measurement (M04.D-M.1; CC.2.4.4.A.1). The students will also continue building their ability to represent and interpret data, with particular emphasis on the ability to organize, display, and answer questions based on data (M04.D-M.2; M04.D-M.2.1; CC.2.4.4.A.2; CC.2.4.4.A.4). Additionally, students will be working on the concept of geometric measurement - understanding the concepts of an angle, as well as measuring and creating angles (M04.D-M.3; CC.2.4.4.A.6).
