How do we operate on numbers?
What algorithms or procedures do we use and why?
Do we always have to use the same procedure?
When is estimating better, than using a precise algorithm?
Once we finish our proportional reasoning unit with relation to measurement conversions and place value, we'll move on to the operations.
We'll start with the big concept by asking the question: Why and How do Mathematicians Like Us Operate on Numbers?
Then we'll practice operating on numbers in many ways to show that there is not one way to get to the desired solution, and getting to the desired solution depends on understanding the question well.
Once we've established that there are many paths, we'll then discuss the fact that in some cases precision is absolutely necessary. Using estimation as a first step helps you to make that next step which is finding the precise solution.
Then we will learn, review, and practice precise algorithms for each operation as we solve multiple real-world word problems.
