There are three worksheets in this file. The worksheets are differentiated by the students level (meeting, exceeding and approaching). All problems are scaffolded to help students master the standard. There are basic problems and also word problems. Each level has a challenge yourself question which takes the student's learning to the next level. According to the CCLS students need to justify their thinking. To meet this requirement the word problems have written responses to it where students have to describe how they arrived at their answers. Hope you enjoy!
