 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 MA2015 (2016) Grade: 6 8 ) Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts explaining the meaning of 0 in each situation. [6-NS5] NAEP Framework NAEP Statement:: 8NPO1d: Write or rename rational numbers. NAEP Statement:: 8NPO1e: Recognize, translate or apply multiple representations of rational numbers (fractions, decimals, and percents) in meaningful contexts. NAEP Statement:: 8NPO1h: Order or compare rational numbers (fractions, decimals, percents, or integers) using various models and representations (e.g., number line). NAEP Statement:: 8NPO5e: Apply basic properties of operations. Alabama Alternate Achievement Standards AAS Standard: M.AAS.6.8- Identify positive and negative numbers in real-world situations (e.g., using visual representations related to credits/debits, temperatures above/below zero). Mathematics MA2015 (2016) Grade: 6 9 ) Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates. [6-NS6] a. Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., - (-3) = 3, and that 0 is its own opposite. [6-NS6a] b. Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes. [6-NS6b] c. Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane. [6-NS6c] NAEP Framework NAEP Statement:: 8A2c: Graph or interpret points represented by ordered pairs of numbers on a rectangular coordinate system. NAEP Statement:: 8NPO1d: Write or rename rational numbers. NAEP Statement:: 8NPO1e: Recognize, translate or apply multiple representations of rational numbers (fractions, decimals, and percents) in meaningful contexts. NAEP Statement:: 8NPO1g: Find or model absolute value or apply to problem situations. NAEP Statement:: 8NPO1h: Order or compare rational numbers (fractions, decimals, percents, or integers) using various models and representations (e.g., number line). NAEP Statement:: 8NPO5e: Apply basic properties of operations. Alabama Alternate Achievement Standards AAS Standard: M.AAS.6.9a- Identify positive and negative numbers on a number line. M.AAS.6.9b- Locate or plot positive and negative numbers on a number line. M.AAS.6.9c - Find given points between -10 and 10 on both axes of a coordinate plane.
