Law of Cosines Task Cards, HW, QR, self checking.
This product is designed for PreCalculus and Trigonometry though can be used in Algebra 2 with certain curricula.
Included in this Lesson:
* Task Cards:
There are two sets of 10 cards. One set has QR codes and the other is without. Students do not need to be on the internet to use the QR but must have a device on which the app is installed. My students love the independence of checking their own answers and having the chance to fix mistakes before turning in their work. And, of course, they love technology.
There are six problems using the Law of Cosines to solve triangles or to find a specific side or angle. There are also four real world applications
using the Law of Cosines.
* Handout with 5 problems
which can be used as enrichment, homework, group work, or as an assessment. Two of the problems are applications.
*Student response sheets
with room for students to show their work. The response sheets are unnumbered so you may choose the cards you want if you think ten is too many.
*All Answer keys
*How to Use task Cards Guide
