Trigonometry Intro Investigation
These two worksheets should be printed out. It has been scaled so that when pupils measure with a ruler each 'box' is 1cm x 1cm. Pupils take the required measurements and are asked if they have observed any similarities between O/A. The tan ratio is then introduced! Lots of calculator use is encouraged. Find out the tan of 30º, what about 45º? 1? What does that mean? Feedback would be appreciated as I am a student teacher.
