MATH LESSON PLAN FOR MICRO TEACHING
Subject: Math
|
Date: Oct. 16, 2019
|
Duration: 15 minutes
|
Introduction
|
Trigon"
is Greek for “triangle”, and "metric" is Greek for
measurement. This lesson will help students to understand the concept of the
primary trigonometric ratios are special measurements of a right
triangle (a triangle with one angle measuring 90°) and
it's importance.

Warm-Up
|
Students will be asked to identify
right-angles, hypotenuses, and similar triangles, based on visuals provided by the teachers.
*If students struggle to review
these concepts, more time will need to be allotted to review before
introducing trig ratios*
Questions for assessing
understanding: “Where do you see right-angles or right triangles in everyday life?”

Assessment/Evaluation of Students’ Learning
|
Students should demonstrate the
difference between the Cos ratio and the Sin ratio.
Students should consistently
identify the adjacent, opposite, and hypotenuse sides of a right-angled
triangle.

Thanks Joel, Hemlatta and Brenda. There's lots of good stuff in your lesson plan, but I also have some questions and suggestions for you:
ReplyDelete• If your lesson plan includes a worksheet or any other handouts or written materials, these should be included as addenda to your lesson plan! (I know I didn't specify that earlier -- but please do add your worksheet to your blogs if you can this evening).
• You teach the students the 'how' of finding sine and cos ratios for an angle, but nothing about the 'why'. I know it's only a 15 minute lesson, but you should think through for yourselves why we teach these 'how to' procedures, and give your students at least a brief hint about why trigonometry is so exciting, powerful and important!
Cheers!
