Ok now for the Geometry skills pulled from the ACT website. You will probably notice some overlap from the Algebra 1 CRS Skills, but that is to be expected. They are in random order.
Comment freely.

Use the Pythagorean Theorem.
Apply basic trigonometric ratios to solve right-triangle problems.
I'm not sure if you are wanting to reduce this list or if you are comfortable with its length. I really only see about 1/3 (or less) of these as Geometry targets. So, if you wanted to reduce the list, you could simply combine the many Algebra skills into the target skill "demonstrates an understanding of prerequisite Algebra skills necessary for application to Geometry standards" and then focus more of your assessment on the emerging Geometry. Just a thought.
ReplyDeleteOf course, if you are comfortable with its length and plan to spend time reteaching the Algebra skills to this degree... You have a better idea of how much Algebra instruction you embed into your Geometry teaching.
