Districts are encouraged to customize this lesson b supplementing with districtapproved resources, materials, and activities to best meet the needs of learners. The duration for this lesson is onl a recommendation, and districts ma modif the time frame to meet students needs. To better understand how our district is implementing CSCOPE lessons, please contact our child s teacher. (For our convenience, please find linked the TEA Commissioner s List of State Board of Education Approved Instructional Resources and Midccle State Adopted Instructional Materials.) Lesson Snopsis: Students plot integers and positive rational numbers on the coordinate plane and identif the quadrant in which the point lies. Students transform figures on the coordinate grid described as a translation or a reflection. TEKS: The Teas Essential Knowledge and Skills (TEKS) listed below are the standards adopted b the State Board of Education, which are required b Teas law. An standard that has a strike-through (e.g. sample phrase) indicates that portion of the standard is taught in a previous or subsequent unit. The TEKS are available on the Teas Education Agenc website at Geometr and spatial reasoning.. The student uses coordinate geometr to describe location on a plane. The student is epected to: 7.7A Locate and name points on a coordinate plane using ordered pairs of integers. Supporting Standard 7.7B Graph reflections across the horizontal or vertical ais and graph translations on a coordinate plane. Readiness Standard Underling Processes and Mathematical Tools TEKS: 7.4 Underling processes and mathematical tools.. The student communicates about mathematics through informal and mathematical page of 48

2 Enhanced Instructional Transition Guide / Unit 04: Suggested Duration: 6 das language, representations, and models. The student is epected to: 7.4A Communicate mathematical ideas using language, efficient tools, appropriate units, and graphical, numerical, phsical, or algebraic mathematical models. Performance Indicator(s): Grade7 Unit04 PI0 Graph and label a set of ordered pairs of integers that will create a figure on a coordinate plane. Reflect the figure over the horizontal or vertical ais. Graph a translation of the figure. In writing, describe how to locate and name the ordered pairs of the image, and identif the quadrant in which it lies. Sample Performance Indicator: Given the points A (-, ), B (-5, 6), and C (-6, ), plot and label the points on a coordinate plane. Graph a reflection across the -ais and label the vertices of the image with prime notation. Net, translate the original figure 7 units down and units to the right, and again label the vertices of the image with prime notation. On the coordinate plane, locate and name the ordered pairs of each image, and identif the quadrants in which the lie. Write a journal entr describing how the vertices were transformed in each of the new images. Standard(s): 7.7A, 7.7B, 7.4A ELPS ELPS.c.5B, ELPS.c.5G Ke Understanding(s): Each quadrant on the coordinate plane is described b the signs of the - and -values of an ordered pair. The order and signs of the coordinates in an ordered pair communicate the location of a point on the coordinate plane. Translations and reflections of shapes can be described and named in terms of coordinates or directions and units. When a figure is transformed on a coordinate grid, the transformation can be described as a translation or reflection. Misconception(s): Some students ma think the order of the coordinates in an ordered pair is not significant. Each coordinate represents the number of units in a specific direction (: left or right, : up or down) and together describe a specific location or point. Some students ma think the quadrants are numbered clockwise instead of counter-clockwise. Some students ma think that Quadrant II should be Quadrant I. page of 48

3 Enhanced Instructional Transition Guide / Unit 04: Suggested Duration: 6 das Some students ma think a translation or a reflection does not create a congruent image. However, when the transformation is performed, the image is congruent to the original figure.

Instruct students to replicate the solutions on their handout: Integers and the Coordinate Plane. Facilitate a class discussion about the coordinate plane. Ask: Notes for Teacher Plane ( per teacher) Handout: Integers and the Coordinate Plane ( per student) How are the horizontal and vertical aes similar? Different? (Both are number lines showing the set of integers. The horizontal ais goes from east to west and the vertical ais goes from north to south. The horizontal ais has the positive integers to the right of 0 and the negative integers to the left of 0. The vertical ais has the positive integers above 0 and the negative integers below 0.) What happens when the horizontal ais intersects with the vertical ais 0? (There are number lines intersecting at 0 with 4 separate regions and we create a wa to show the location of a point with a horizontal and vertical direction.) What is the place called where the horizontal and vertical number lines intersect? (origin) How would the location where the horizontal and vertical number lines intersect be described using an ordered pair?
