Discovery Properties of Rhombus, Rectangle, Square, Parallelogram | Activity
Geometry discovery activity allows students to explore classifying special quadrilaterals properties for special quadrilaterals: parallelograms, rectangles, rhombus and squares with ruler and protractor. Students plot each special quadrilateral on 4 provided coordinate grids. Students are then guided to find the measures of specific side-lengths and angles; also finding slope (using formula or rise/run) determine parallelism and right angles. Emphasis is placed on understanding opposite and adj

Teaching style
Students should be encouraged to make mistakes because "mistakes are proof that you are trying" (Samantha Snyder). Students should also feel a sense of community in the classroom, where he/she feels extremely comfortable asking questions and even confident enough to let the teacher know if he/she made a mistake.
Each student has his/her own way of learning, and it is vital for a teacher to be able to distinguish whether a particular student is an auditory and/or visual learner. Similarly, there is no "right way" of teaching - each teacher has his/her own unique teaching style that works as long as the main focus of the job is the student.
