Standards

Florida Sunshine State Standards
MA.C.2.1.1.2.1
The student describes symmetry in two-dimensional shapes.

MA.C.2.1.1.2.2
The student determines lines of symmetry of two-dimensional shapes by using concrete materials.

MA.C.2.1.1.2.3
The student knows congruent shapes.

MA.C.2.1.1.2.4
The student identifies shapes that can be combined or separated (for example, a rectangle can be separated into two triangles).

MA.C.2.1.1.2.5
The student predicts the reflection of a given two-dimensional shape.

MA.C.3.1.2.2.2
The student locates and identifies the coordinate points of objects on a coordinate grid (first quadrant).

Florida Process Standards
Information Managers
01 Florida students locate, comprehend, interpret, evaluate, maintain, and apply information, concepts, and ideas found in literature, the arts, symbols, recordings, video and other graphic displays, and computer files in order to perform tasks and/or for enjoyment.

Effective Communicators
02 Florida students communicate in English and other languages using information, concepts, prose, symbols, reports, audio and video recordings, speeches, graphic displays, and computer-based programs.

Numeric Problem Solvers
03 Florida students use numeric operations and concepts to describe, analyze, communicate, synthesize numeric data, and to identify and solve problems.

Critical and Creative Thinkers
04 Florida students use creative thinking skills to generate new ideas, make the best decision, recognize and solve problems through reasoning, interpret symbolic data, and develop efficient techniques for lifelong learning.

Preparations

1) Have available a large clean surface on which you can draw, and then easily erase portions of the drawing.
2) Print out a copy of the complete lesson instructions from the Attached Files.
3) Review the procedures as described in the instructions so the lesson will flow smoothly.

Assessments

Formative assessment occurs as students watch and observe as the coordinate grid is drawn on the board. As students respond to questions and offer suggestions as to what is being created, listen for associations that give clear evidence that students are thinking about quilts, shapes within shapes, horizontal and vertical, congruent, reflections, symmetry, and line of symmetry. There should be clear transition of knowledge with regard to points, squares, and geoboards (studied in the unit Geo Jammin'). Identity and location of coordinate points on the coordinate rid is formatively assessed as individual students tell how to locate a given point as the teacher follows their directions and marks it on a grid. Listen for students starting at the origin point and counting to the right first and then up, and by checking individual student glossaries for the correct meaning of coordinates and coordinate geometry. Use data gleaned from student participation and work to guide further instruction.
