__Standards and Benchmarks Covered in this Lesson__

II,3,1:
Select and use appropriate tools; make accurate measurements using both metric and common units, and measure angles in degrees
and radians.

II,3,5:
Use proportional reasoning and indirect measurements including applications of trigonometric ratios, to measure inaccessible
distances and to determine derived measures such as density.

__Introduction__

Anticipatory
Set: Warm up cartoon and Pythagorean Theorem review.

Objectives: After students measured the lengths of triangles and we briefly discussed the Pythagorean Theorem yesterday
and going over the warm-up today, students will be able to complete the investigation they began yesterday.

__Investigation__

Students
will finish up investigation 1 of lesson 2 today. I will guide them to a deeper
understanding of the content by giving multiple representations of the content and by asking carefully designed questions.
