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

This investigation give students the opportunity to discover how standard deviation relates to normal distribution. Materials: Dice, access to books or white boards Teacher Moves: Students start investigation straight away, no instruction required. Students should have already learned about how to calculate standard deviation as a measure of spread. He students will discover that in normally distributed data sets, approximately 67% of the data lies within one standard deviation.
