If you want your students to start the trigonometry unit with a deeper conceptual understanding this investigation is for you! This lesson goes to the heart trigonometry is all about. Ratios! Students are geared with solving the problem of "ranking" wooden beam angles from lowest to highest. Some students will sort the angles by drawing them to scale, others will be able to find the angle via dividing the opposite by the adjacent. Only some vocabulary introduced as needed, only one trig ratio

Students can discover the way in which numbers are broken up into their prime factors. Teacher Moves: Let the students start straight away to work collaboratively to decipher what the components of factors trees. Afterwards, students complete discussion questions to consolidate their conceptual understanding.
