This is the twelfth lesson in my Place Value unit. It is designed to take the class through the vocabulary words of sums and differences and to review rounding from the previous lesson. After the introductory slides, the lesson then moves to interactive activities to check for the students understanding of the concept. The numbers and boxes are designed to be moved for individual students to come up to the board to display their answers and explain their reasoning. There are many practice slides for multiple students to be in charge of placing their rounded number in the appropriate column or solving the problems, making this lesson interactive for every student in the class.
