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.
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.
Note: Units of measurement are in cm
