This worksheet guides students though mentally calculating tips in their head. It shows students how to quickly solve for 5%, 10%, 15% and 20% tips. At the top of the worksheet there is a quick example and though out the sheet are scaffolded examples which helps the students solve the problems. On the second page there are examples who you tip as well as some facts about tipping. This worksheet is the following 6th grade Common Core Standard (CCS) 6.RP.A.3.C. but could also be used for 5th grade and 7th grade. This worksheet also works very with students who have various disabilities such as Aspergers, Autism, ADD, ADHD etc due to the scaffolding, visual examples, and tracing portions of the worksheet. This worksheet also teaches perseverance and test taking tips by throwing in a more difficult question into the middle of the worksheet but encouraging the student to skip the question till the end. This is something that I constantly am trying to teach my students but I never see modeled in worksheets.
