We are discussing place value and adding and subtracting large numbers. We will have our unit test next week, November 17th. Students will need to add and subtract using the strategies below. The idea is to show their understanding of place value instead of moving through the motions to "remember" the method. They will also need to compare numbers through 1 million. Here are a couple fun sites that walk students through the steps for interactive practice as well as some student created examples.
