Core Ten is a bellwork program that can be used for sustained learning over time. The problems are based on common core. I have chosen ten standards to focus on and students work on two problems each day at the beginning of class. Worksheets are collected and graded at the end of the week. Each week problem #1 will focus on 8.EE.1, #2 will focus on 8.NS.2, #3 will focus on 8.G.9, #4 will focus on 8.EE.5, #5 will focus on 8.EE.7, #6 will focus on 8.F.4, #7 will focus on 8.EE.8, #8 will focus on 8.G.7, #9 will focus on 8.G.2, and #10 will focus on 8.EE.3.
Weeks 1-4 have very similar problems and students are quizzed at the end of the 4th week. Then weeks 5-8 are similar problems and again students are quizzed at the end of week 8. I have 20 weeks of bellwork and 5 quizzes complete and ready for purchase if you like this worksheet! The quizzes are a great way for students to see improvement over time.
I start the year with these and usually have to guide the students through the problems for a few weeks. Once the year gets going students work on the problems at the beginning of class on their own, then we go over them together. It is a great way to introduce topics. For example student will have done the Pythagorean Theorem before we even get to that unit. So once it is time to teach the unit - they have already been exposed to problems. It is also a great way to review and incorporate spiral learning in your classroom.
