Lesson Seeds: The lesson seeds are ideas for the indicator/objective that can be used to build a lesson. Lesson seeds are not meant to be allinclusive, nor are they substitutes for instruction. 
Standard 2.0 Knowledge of Geometry 
Topic E. Transformations 
Indicator 1. Analyze a transformation on a coordinate plane 
Objective a. Identify, describe, and plot the results of multiple transformations on a coordinate plane 
Materials needed 

Coordinate grids for each student, transparency coordinate grid (teacher), worksheets with polygons (basic polygons, i.e., square, rectangle, triangle) for each student, colored transparency polygons (square, rectangle, triangle, pentagon) (teacher). 
Activity 
Make sure your polygons fit exactly on the grid paper i.e. the coordinates of their vertices are integral. One way to do this is to color shapes on one copy of the grid, cut them out, and paste them onto a worksheet.
Note: Students should be made aware that the results of some transformations can look alike, i.e. a translation of a square, might appear to also be a reflection of that same square.
