This Instructional Activity is a part of the Lesson 10, Unit 1, Grade 6. This activity, and the demonstration needed to launch it, gives students a concrete strategy for identifying a height accurately. When students use a strategy of drawing an auxiliary line to solve problems, they are looking for and making use of structure. Explicit instruction, as in this activity, is often needed before students can be expected to use this strategy spontaneously.
