Tenth graders explore volume and surface area through percentages. In this geometry lesson, 10th graders analyze the surface area of two and three dimensional shapes, then use percents and ratio to compare the two.

Students create a sextant. Using their sextant, students measure the height of tall objects. Students explore how sailors used sextants to identify their location on the ocean. They research how sextants are created.
