I am a big fan of using the curriculum and resources from Math in Focus. However, there are no progress monitoring checks or quick quizzes throughout the unit to check on students' basic skill knowledge. I created this mastery check to check students' fundamental skill knowledge and remediate as necessary. I have 10 or 5 questions for easy scoring and mastery calculation. There are 10 questions on rounding, 10 on estimating, 10 points for factors and greatest common factors, and 5 on multiples.
