Operations and Algebraic Thinking: Students will extend understanding of multiplication and division and apply operational properties to solve problems involving variables.

Add and subtract multi-digit numbers using an algorithm.

Multiply up to a four-digit whole number by a one-digit whole number and multiply a two-digit whole number by a two-digit whole number, using strategies based on place value, properties of operations, and algorithms.

Divide up to a four-digit whole number by a one-digit divisor with and without a remainder using strategies based on place value.

Determine the reasonableness of whole number products and quotients using estimations and number sense.

Create a simple algebraic expression or equation using a variable for an unknown number to represent an authentic mathematical situation (e.g., 3 + n = 15, 81 ÷ n = 9).

Solve one- and two-step authentic problems using the four operations including interpreting remainders and the use of a letter to represent the unknown quantity.

Students will solve problems and reason with number concepts using multiple representations, make connections within math and across disciplines, and communicate their ideas.

Solve problems and reason with algebra using multiple representations, make connections within math and across disciplines, and communicate their ideas.

Solve problems and reason with geometry using multiple representations, make connections within math and across disciplines, and communicate their ideas.

Solve problems and reason with data/probability using multiple representations, make connections within math and across disciplines, and communicate their ideas.

Data Collection: Students will formulate questions to collect, organize, and represent data.

Generate and represent data using line plots where the horizontal scale is marked off in appropriate units—whole numbers, halves, fourths, or eighths.

Analyze Data and Interpret Results: Students will analyze the data and interpret the results.

Solve authentic problems and analyze data involving addition or subtraction of fractions presented in line plots.

Shapes and Their Attributes: Students will draw and identify lines and angles and classify shapes by properties of their lines and angles.

Identify, create, and describe points, lines, line segments, rays, angles, parallel lines, perpendicular lines, and intersecting lines.

Justify the classification of angles as acute, obtuse, or right.

Justify the classification of two-dimensional shapes based on the presence or absence of parallel and perpendicular lines or the presence or absence of specific angles.

Recognize, draw, and justify lines of symmetry in two-dimensional shapes.

Measurement: Students will generate simple conversions from a larger unit to a smaller unit to solve authentic problems and measure angles.
