Objectives

Students will be able to...

1. Represent reflections in the plane using, e.g., transparencies and geometry software

2. Describe reflections as  functions that take points in the plane as inputs and give other points as outputs. 

3. Compare reflections that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch).

4. Given a rectangle, parallelogram, trapezoid, or regular polygon, describe reflections that carry it onto itself.

5. Represent, describe, and compare reflections in the plane using geometric software: IXL.

1 IXL: Interactive Geometry Practice

Finally, the IXL summative assessment allows me to collect a numeric measurable percentage of correct/incorrect solutions and how many attempts the students took to reach the required “smart score.” Students will have the option of Level L.1- L.8 ad be required to complete 5 of 8 levels and achieve a smart score of 60. For the second
 Students will have the option of Level L.7, L.8, L.9, L.10, and L.12 and be required to choose three levels and reach a smart score of 80. This quantitative data will allow me to solidify the percentage of the class that demonstrated learning of the instructional outcomes.

The IXL teacher view allows the to view each students progress in real-time.  IXL alerts the teacher if a student has attempted multiple problems and has not gotten many correct. This gives the teacher an opportunity to see which students need one-on-one assistance.

The quantitative data also allows the teacher to record students understanding of the lesson and also evaluate teaching effectiveness.
