Assign the following activities for homework and share the following fivewebsites to review concepts from today's lesson and prepare for the nextsession.5. Assignmentsa) Have students colour the polygons on the pattern block page:• Hexagon (yellow)• Trapezoid (red)• Square (orange)• Triangle (green)• Thin rhombus (tan)• Other rhombus (blue)Then have them cut out the shapes and record two things:• The measure in degrees for each polygon's angles—without using a protractor• Different ways that various shapes can be arranged around a single point tomake a 360° angle. Have them use the angles-around-a-point handout torecord discoveries.(Students can also experiment with this activity by using the virtual patternblocks from the website below.)b) Have students cut out a variety of quadrilaterals (squares, rectangles, rhombuses,trapezoids, parallelograms, and non-defined 4-sided figures).Using the same process that was done with triangles, have them label and rip off thecorners and arrange them. What patterns do they notice?c) Cut out more quadrilaterals. Cut them in half on a diagonal. What do they noticeabout the resulting shapes? What about their angle sum? How does that angle sumrelate to the angle sum they found in other quadrilaterals? Why do they think this isso?d) Look through the following resources:• Angle descriptions with photographs: http://tinyurl.com/Angle-Types• Angle descriptions with animation: http://tinyurl.com/Angle-Animation• Angle tutorial: http://tinyurl.com/Angle-Tutorial• Naming and Measuring angles (video): http://tinyurl.com/Angle-Name-Measure• Virtual pattern blocks: http://tinyurl.com/Virtual-Pat-Blockse) Have students bring the coloured-in cutout pattern blocks to the next class session.
