 Lesson Plan ID: 33134 Title: You Sank My Coordinate Plane! (an introductory lesson in coordinate planes) Overview/Annotation: If you grab a bunch of jump ropes and tell your kids you're going outside, you can trick them into thinking they are getting recess. Instead, you can surprise them with a math lesson about how to identify the points on the coordinate plane! This is a College- and Career-Ready Standards showcase lesson plan.
Associated Standards and Objectives
Content Standard(s):
 Mathematics MA2015 (2016) Grade: 5 23 ) Use a pair of perpendicular number lines, called axes, to define a coordinate system with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate). [5-G1] NAEP Framework NAEP Statement:: 4A2c: Graph or interpret points with whole number or letter coordinates on grids or in the first quadrant of the coordinate plane. NAEP Statement:: 4G4a: Describe relative positions of points and lines using the geometric ideas of parallelism or perpendicularity. Alabama Alternate Achievement Standards AAS Standard: M.AAS.5.23- Identify quadrant 1 and the origin on a coordinate system grid. Mathematics MA2019 (2019) Grade: 5 20. Graph points in the first quadrant of the coordinate plane, and interpret coordinate values of points to represent real-world and mathematical problems. Unpacked Content Evidence Of Student Attainment:Students: Use the first quadrant in a coordinate plane to identify coordinates of a given point. Use the first quadrant in a coordinate plane to explain how the location of an ordered pair is determined. Given a real-world situation involving a relationship between two variables, graph a representation of the situation and interpret coordinate values of the points in the context of the problem. Given a graph representing a real-world situation, interpret the coordinate values of the points in the context of the situation.Teacher Vocabulary:Coordinate system Coordinate plane First quadrant Points Lines Perpendicular X-axis Y-axis Origin Ordered pair Coordinate plane Horizontal Vertical Intersection of linesKnowledge:Students know: Specific directions and vocabulary to explain ordered pair location. The first number of an ordered pair indicates how far to travel from the origin in the direction of one axis and the second number indicates how far to travel in the direction of the second axis.Skills:Students are able to: Graph points in the first quadrant. Interpret coordinate values in context of the problem.Understanding:Students understand that: graphing points on a coordinate plane provides a representation of a mathematical context which aids in visualizing situations and solving problems.Diverse Learning Needs: Essential Skills:Learning Objectives: M.5.20.1: Define ordered pair of numbers, quadrant one, coordinate plane, and plot points. M.5.20.2: Label the horizontal axis (x). M.5.20.3: Label the vertical axis (y). M.5.20.4: Identify the x- and y- values in ordered pairs. M.5.20.5: Model writing ordered pairs. Prior Knowledge Skills:Graph points in the first quadrant. Interpret coordinate values in context of the problem. Alabama Alternate Achievement Standards AAS Standard: M.AAS.5.20 Identify a point on a horizontal number line representing the horizontal x-axis (no greater than 5) and identify a point on a vertical number line representing the y-axis (no greater than 5).

Local/National Standards:

Primary Learning Objective(s):

Students will be able to identify the four quadrants, point of origin, both the x and the y axis, and an (x,y) position on the coordinate plane--first on the playground, and then on paper.
