Product Description
Teach your students everything they need to know about 2D geometry! This print and teach unit covers everything from polygons to constructing shapes.
In this download you will get a 40 page student booklet, a summative assessment and all the additional handouts you will need to teach a complete 2D geometry unit. All the lessons are three part (Getting Started, Working On It/Problem of the Day and Reflect and Connect). There are a variety of instructional strategies such as: videos, I have Who has game, cut and paste, foldable, student created anchor chart, webquest, bump it up, and challenging problems.

Lessons:

Lesson #1: Polygons
Getting Started: Polygons video, cut and paste key terms matching
Working On It: Cut and paste activity. Students identify examples of polygons and non-polygons.
Shapes review: students identify the names of the following shapes: rectangle, pentagon, isoscelese triangle, square, hexagon, scalene triangle, parallelogram, right angle triangle, ocatagon.
Properties of Shapes Review: students compete a cut and paste activity to identify several properties of shapes (congruent sides, interior angles, quadrilateral, equal angles, vertex, etc
Reflect & Connect: Students draw examples of polygons, quadrilaterals, shapes with congruent sides and a right angle triangle.

Lesson #2: Congruent Shapes (2 periods)
Getting Started: Multiple choice problem solving question (involving coordinates)
Students find congruent shapes around the room, and watch a video about angles.
Foldable: students create a foldable, to identify properties of acute, right and obtuse angles and draw an example of each.
Working On It: Students practice identifying congruent shapes and colour a quilt with a congruent pattern.
Working On It Con’t: Students identify angles as acute, right or obtuse.
Reflect & Connect: Students divide a parallelogram into two congruent triangles, and solve a problem involving coordinates and congruent shapes.

Lesson #3: Protractors
Getting Started: Video about how to read and use a protractor. Students label the parts of a protractor.
Working On It: Students measure angles (imaged with protractor).
Ticket: Students measure all the angles they see in a stick character.

Lesson #4: Measuring Angles
Getting Started: I Have, Who Has angles game
Video and student anchor chart, % Key Steps to Drawing Angles
Working On It: Students use protractor to draw angles given their measurements.
Lesson #5: Interior Angles (Getting Ready to Construct Shapes)
Getting Started: Video about interior angles, student fill in anchor chart about the sum of interior angles of: triangles, quadrilaterals, and pentagons.
Working On It: Students identify 3 shapes and determine the sum of the interior angles of each.
Problem Of the Day: Students construct a pentagon, given several properties of the shape (right angle, angle measuring 110 degrees, a side measurement). Students construct the shape and calculate the sum of it’s interior angles.

Lesson #6: Symmetry
Getting Started: Symmetry webquest. Students explore the concept and find information about line symmetry, symmetry in architecture, rotational symmetry etc.
Working On It: Students will practice drawing line symmetry in an assortment of shapes.
Reflect & Connect: Students will construct a pentagon that follows a list of properties, including line symmetry.

Lesson #7: Rotational Symmetry
Getting Started: Students watch a video about rotational symmetry. Student take jot notes about rotational symmetry and order of rotation. Students also list some real world examples of rotational symmetry.
Working On It: Students identify shapes with rotational symmetry.
Reflect & Connect: Students design their own company logo that has rotational symmetry.

Lesson #8: Putting It All Together
Getting Started: Students sort polygons using a Venn diagram (1 line of symmetry and rotational symmetry)
Problem o the Day: Students construct a parallelogram and trapezoid given several properties and identify the sum of interior angles.
Reflect & Connect: Students continue to construct shapes given properties (quadrilateral, a shape with rotational symmetry order 3)

Lesson #9: Bump It Up
Students identify the problems with the construction of a shape (parallelogram) and bump it up.
