25. Use a protractor to measure angles in whole-number degrees and sketch angles of specified measure.

This lesson is designed to teach students to measure angles with a protractor. The student will be taught how to read the protractor correctly by using either the top or bottom set of numbers. The lesson will reinforce classifying angles as acute, right, and obtuse. The student will sketch angles given a specified measure.

*This lesson results from the ALEX Resource Gap Project.*

25. Use a protractor to measure angles in whole-number degrees and sketch angles of specified measure.

[ARTS] VISA (4) 2 : 2) Collaboratively design and create artwork that has meaning and purpose.

Examples: Create a logo for a school or activity.

In this learning activity, students will watch a video to review right, acute, and obtuse angles. Students will create various angles using strips of construction paper. Finally, students will measure their newly created angles with a protractor.

*This activity was created as a result of the Arts COS Resource Development Summit.*

25. Use a protractor to measure angles in whole-number degrees and sketch angles of specified measure.

In this interactive activity, students will be led through steps to measure angles using a protractor. There are teaching activities as well as practice activities available. A handout that reviews the steps taught during the activity can be printed. A karaoke song with printable lyrics will help students learn and review the steps taught during the activity. After utilizing this resource, the students can complete the short quiz to assess their understanding.

23. Calculate, interpret, and compare measures of center (mean, median, mode) and variability (range and interquartile range) in real-world data sets.

a. Determine which measure of center best represents a real-world data set.

b. Interpret the measures of center and variability in the context of a problem.

This classroom resource provides a video that describes how to use a circle graph to analyze data. The vocabulary words sector and protractor will be introduced. After utilizing this resource, the students can complete the short quiz to assess their understanding.
