Standards Addressed:
MGSE.9-12.G.CO.2. Represent transformations in the plane using transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not.
MGSE.9-12.G.CO.4 Develop definitions of rotations, reflections and translations in terms of angles, circles, perpendicular lines, parallel lines and line segments.
MGSE.9-12.G.CO.5. Given a geometric figure and a rotation, reflection or translation, draw the transformed figure using graph paper, tracing paper or geometry software. Specify a sequence of transformations that will carry a figure onto another.
Learning Target/Success Criteria:
I can recognize that rotations, reflections and translation preserve side lengths and angle measures creating congruent figures.
I can identify a reflection on the coordinate plane.
I can write the rule for a reflection given the pre-image and image.
I can graph a reflection on the coordinate plane given a rule.
I can translate a figure on the coordinate plane and identify the coordinates of the image.
I can identify the rule for a translated figure on the coordinate plane.
I can write the rule for a translation using arrow notation.
I can rotate a figure on the coordinate plane and identify the coordinates of the image.
I can identify/write the rule for a rotated figure on the coordinate plane.
Introduction/Connection: students will complete multiple choice Transformations Review and Transformations Review identify rule (both attached below). Review whole group.
Direction Instruction/Guided Practice:
--Review bellringer.
--Blooket review of transformation rules (rotations, reflections, translations)
Resources: DeltaMath, Blooket
Assignment: Students will complete 3 DeltaMath assignments:
1) Reflections Practice
2) Translations Practice
3) Rotations/Reflections Review
