Our Addition/Subtraction lesson plan helps students explain why addition and subtraction strategies work using place value and the properties of operations. At this level, most students know basic addition and subtraction facts, but our lesson teaches students the “why” behind the operations. Students will be asked to work collaboratively to solve word problems using two different strategies. Students are also asked to demonstrate their understanding completing both numerical and word problems on their own using what they learned in the lesson.
The students will be able to explain why addition and subtraction strategies work, using place value and the properties of operations.
