Students are introduced to integers and rational numbers, extending the number line to include negative values, understanding the order of rational numbers, and interpreting them in context.
Math
Unit 4
6th Grade
In Unit 4, 6th grade students extend their understanding of numbers to include rational numbers. Prior to this unit, students have worked only with positive values, and their concepts of number lines and coordinate planes have been limited by these positive values. Students explore real-world situations that naturally connect to negative values, such as temperature, money, and elevation. The number line is a valuable tool that is referred to and used throughout the unit. Students use the number line to develop understanding of negatives, opposites, absolute value, and comparisons and inequalities (MP.5). They also discover the four-quadrant coordinate plane by intersecting two number lines at a 90-degree angle and representing locations using ordered pairs.
In elementary grades, students build and develop their sense of number with positive values. They use the number line as a tool to better understand whole numbers, fractions, and decimals. In 5th Grade Math, students look at the first quadrant of the coordinate plane and represent locations using ordered pairs of positive numbers. In 6th grade, students build on and extend these concepts to include negative values.
In 7th Grade Math, students will discover how to compute with rational numbers and what happens when the properties of operations are applied to negative values. The work they do in this unit is foundational to these 7th-grade concepts.
