This 23 page document is a Unit One Practice Benchmark for second graders. All of the topics are directly taken from the NJ Model Curriculum Benchmark (Grade 2 Unit 3) that supports Common Core. The document can be displayed nicely on a SmartBoard for class instruction or printed out for individual practice. Personally, I print the document (four pages onto one page, landscape) and use on the SmartBoard with the entire class. Students get to practice solving independently, and they love going to the SmartBoard to share their answers. Depending on the class and the length of time available, it may take one to two hours to complete.
