There are new sets of additional practice questions for all units of CMP3. These can be found as Additional Practice ACTIVe-Books in English and Spanish, one per grade, on the Dash digital bookshelves for students and teachers. In addition, printable pdf files of the practice content along with answer keys are accessible through the links menu (upper right corner of the screen) in each grade's Teacher Place on Dash.
Please note that while you must log in to the Teacher Place in order to access the Additional Skills Practice printable materials, the URL you are taken to for accessing them is NOT protected. So, if you show the URL to your students, they would be able to access that website directly (including the answers). However, there is no Student access via their Student logins to Dash.
