I truly like the new navigation map and its tabs.Outstanding
Dear Mr. Cerritos, Thank you for your kind words. Please do not hesitate to leave additional feedback in any of our courses. Kind regards, Audra
I like the set up of the homework problem sets! :) I was wondering, will you be doing Unit Plans for this course like the others have? Thanks!
Dear Ms. Yoast, Yes, we have unit plans made in each unit. They can be found in the "Teacher Resource" category (found w/in each unit). Here is a link to the Unit Plan for the Parallel Lines Unit: https://njctl.org/courses/math/geometry/parallellines/attachments/parallellinesunitplan/ Kind regards, Audra
My class has found what we believe are errors in the homework answers. For Rotation homework, the anawer to #3c should be CD and the answer to to #CD. Also #4a and 4c are using the wrong rule. Correct answers for #4a we believe is (D(3,2); E(2,4); F(2,7), G(2,5); Correct answer for #4c is D(3,2); E(2,4); F(2,7); G(2,5). We also believe the answer to #5 is P'(5,1); Q'(4,3); R'(4,2); S'(2,3). Also #8 for the identifying symmetry with transformations. If you trace the figure and try to rotate it, it does not map onto itself.
Dear Ms. Gerdes, Thank you for your comment. We will be making changes to the problems &/or answers that you mentioned within the next few business days. I'll reply again once the updated files have been posted. Kind regards, Audra
Dear Ms. Gerdes, Thank you again for the comment that you left prior to the Thanksgiving holiday. The CWHW file has been changed to reflect the corrections that you mentioned, including the redrawing of the figures in the HW section of Identifying Symmetry with Transformations to make the answers correct. Kind regards, Audra
So what app do you recommend to open the notebook in. I want to get the correct app.
Dear Ms. Shields, Thank you for your comment. Please answer the two questions below & I can provide you with more assistance: 1) What type of computer do you have? 2) What operating system does it run on? For example, a PC can run on Windows 10 & a Mac can run on OS X El Capitan. Kind regards, Audra
