In order to access Google Classroom you may need to download the Google Classroom app or access it using Google Chrome as you search engine. You may find that you cannot access it properly using other familiar search engines.
Once you have Google Classroom installed, please log on using your child's email address and password provided. DO NOT TRY USING YOUR OWN EMAIL AS IT WILL NOT WORK.
