 Lesson Plan ID: 33126 Title: Wonder Number Line Overview/Annotation: This lesson allows students to become familiar with a number line. Students can explore a number line and develop knowledge of numerical concepts. While it covers a 6th grade standard, this lesson can be used as part of a 7th or 8th grade lesson on integers.This is a College- and Career-Ready Standards showcase lesson plan.
Associated Standards and Objectives
Content Standard(s):
 Mathematics MA2019 (2019) Grade: 6 10. Locate integers and other rational numbers on a horizontal or vertical line diagram. a. Define opposites as numbers located on opposite sides of 0 and the same distance from 0 on a number line. b. Use rational numbers in real-world and mathematical situations, explaining the meaning of 0 in each situation. Unpacked Content Evidence Of Student Attainment:Students: Create and interpret number line diagram. Given any rational number (positive or negative). Locate the number on a number line. Identify opposite signs of numbers as indicating the same distance from zero on the opposite side of zero, the opposite of the opposite, or a representation of its opposite as the point itself [-(-3) = 3], and zero as its own opposite.Teacher Vocabulary:Integers Rational numbers Horizontal line diagram Vertical line diagramKnowledge:Students know: Strategies for creating number line models of rational numbers (marking off equal lengths by estimation or recursive halving). Strategies for locating numbers on a number line. Notation for positive and negative numbers and zero.Skills:Students are able to: Represent rational numbers and their opposites on a number line including both positive and negative quantities. Explain and justify the creation of number lines and placement of rational numbers on a number line. Explain the meaning of 0 in a variety of real-world contexts.Understanding:Students understand that: Representing rational numbers on number lines requires using both a distance and a direction, Locating numbers on a number line provides a representation of a mathematical context which aids in visualizing ideas and solving problems.Diverse Learning Needs: Essential Skills:Learning Objectives: M.6.10.1: Define integers, positive and negative numbers. M.6.10.2: Demonstrate the location of positive and negative numbers on a vertical and horizontal number line. M.6.10.3: Give examples of positive and negative numbers to represent quantities having opposite directions in real-world contexts. M.6.10.4: Discuss the measure of centering of 0 in relationship to positive and negative numbers. M.6.10.5: Discover that the opposite of the opposite of a number is the number itself. M.6.10.6: Show on a number line that numbers that are equal distance from 0 and on opposite sides of 0 have opposite signs. M.6.10.7: Define rational number. M.6.10.8: Plot pairs of integers and/or rational numbers on a coordinate plane. M.6.10.9: Arrange integers and /or rational numbers on a horizontal or vertical number line. M.6.10.10: Locate the position of integers and/or rational numbers on a horizontal or vertical number line. M.6.10.11: Identify a rational number as a point on the number line. M.6.10.12: Name the pairs of integers and /or rational numbers of a point on a coordinate plane. Prior Knowledge Skills:Model writing ordered pairs. Identify the x- and y- values in ordered pairs. Label the vertical axis (y). Label the horizontal axis (x). Define ordered pair of numbers, quadrant one, coordinate plane, and plot points. Locate positive numbers on a vertical number line. Examples: thermometer, map. Locate positive numbers on a horizontal number line. Locate negative numbers on a horizontal number line. Label x- and y-axis and zero on a coordinate. Illustrate vertical and horizontal number lines. Specify locations on the coordinate system. Define x-axis, y-axis, and zero on a coordinate. Define ordered pair of numbers. Define parentheses, braces, and brackets. Alabama Alternate Achievement Standards AAS Standard: M.AAS.6.9 Describe quantities with positive and negative numbers (e.g. temperature, sea level, etc.).
