HW: Turn in any missing work from 11.1 - 11.5.
For the first half of class we did a vocabulary review, a review of right triangles created by a tangent and radius, and a review of tangents from the same point outside the circle. Students also received their short vocabulary quiz from yesterday. Students completed their 11.1 - 11.3 quiz today.
HW: Turn in any missing work from 11.1 - 11.5. Students completed a 10 question circle vocabulary quiz. Students completed the WS 11.5 A in class. WS. 11.5 B should be completed as well. HW: complete any missing work through 11.5 quiz tomorrow on 11.1 - 11.3. We went over WS 11.3 after we did our third quick write of this unit. We incorporated the vocabulary from 11.3 on arcs and central angles.
Key point is the inscribed angle is half of its intercepted arc.

Complete WS 11.5 side B only. Vocabulary quiz tomorrow. Students completed a 10 minute quick write of the items they saw in the diagram. We used proper labels as well as the correct vocabulary. Then we completed our note from 11.3 on the types of arcs and we found that the central angle has the same degree as its intercepted arc.

HW: Complete WS 11.2 (both sides) We review the vocabulary of chord, secant, and tangent as well as radius, diameter, and center. We completed our notes from 11.1 and then looked at the relationship between the tangent to a circle and the radius of the circle. We found that they are always perpendicular. This created a right triangle and we could use Pythagorean theorem as well as any right triangle trig (SOH-CAH-TOA).

Then they had the rest of the time to complete WS 11.1. Both sides are due tomorrow.
HW: WS 11.1, both sides. We went over the trig test from last Friday. Then we talked about what students had learned about circles. We also reviewed the parts of the circle such as the center, radius, and diameter. We reviewed the formulas for circumference (C = 2 pi * r) and area (A = pi*r^2).
Use the link for practice https://www.youtube.com/watch?v=O-cawByg2aA HW: Complete WS 11.1 the day 2 side (period 3) and second hour can complete either side. The district post-assessment on trig will be tomorrow. We went through the district pre-assessment for the similarity & trig unit. We found that we could use different techniques to answer a question, suing SOH-CAH-TOA, Pythagorean theorem, similar triangles and inverse trig functions.
HW: Be ready for the district post-assessment tomorrow. We went over any remaining questions on the practice test. This was collected as well as any late/missing work. Students completed their test on right triangle trig.
HW: None |
