Product Description

This smartboard lesson include a full set of directions for using the lesson, a student assignment sheet, a smartboard file, and a set of posters for the special pairs of angles.

The lesson focuses on CCSS 7.G.5.

If you don't have a smartboard or the notebook software you can project this lesson using the web version of smart notebook http://express.smarttech.com.

• The do now for the lesson is on slide 2. Students are asked to pair names, pictures and sizes of 4 different types of angles. The pictures, terms and measures can all be moved.

• The lesson opens with the students being challenged to think about which pairs of angles can be put together to form a right angle. (If you tap to the right of the first star a right angle will appear.) You can slide the angles together to show which angles do form a right angle. Tapping to the right of the second star the students will be reminded that these are called complementary angles.

• The next slide shows pairs of angles and the students are challenged to think about which pairs of angles can be put together to form a straight angle or line. (If you tap to the right of the first star a line will appear.) You can slide the angles together to show which angles do form a straight angle or line. Tapping to the right of the second star the students will be reminded that these are called supplementary angles.

• Slide 5 is just a summary slide showing adjacent complementary and adjacent supplementary angles. After talking about supplementary angles you can slide down the cover sheet to talk about the complementary angles.

• On slide 6 one of two complementary angles measures 25 deg and it is illustrated. Students are asked “What is the other angle?” . By tapping near the missing complementary angle a right angle appears. Use to picture to help students find the missing angle. (65 deg)

• Slide 7 shows two adjacent angles that are neither complementary or supplementary. You can make up a problem for this slide by telling students that the measure of angle ONP is 30 deg and ask them to find the measure of angle MNO. (96 deg)

• In slide 8 students are challenged to think about 2 supplementary angles in a parallelogram. Tap to the right of the star to reveal a parallelogram. Use this slide to introduce writing an equation that describes angles A and D being supplementary. (Measure of angle A + measure of angle D = 180 deg) Then using substitution find that the measure of angle A is 115 deg).

• Slide 9 shows two intersecting lines that for a 130 deg angle. Use this diagram to write appropriate equations. Use the second picture to write equations about w, x, y, and z to say that various pairs add up to 180 deg.

• Slide 10 shows some angles. Use the picture to write several equations.

• Slide 11 introduces slides 12-15.

• Slides 12-15 are four problems that can be assigned to students to solve as part of demonstration of learning.
