It's that time of year....
We are working on knowing our addition and subtraction facts to 10 in a snap! These are facts that we want to know so well that we don't need to use our fingers for help! We also want to know how to write and solve these facts in many different ways. We will be practicing these skills through simple dice games as well as diving into the world of STORY PROBLEMS.
When I think about being a kid and having to solve story problems, I cringe. I never knew what the problem was asking me and I ended up just pulling the numbers out of the sentences and either adding them together or subtracting to come up with some sort of answer. Starting with small numbers and teaching the different types of story problems in kindergarten will give everyone the opportunity to truly understand the different kinds of problems and how you can write a number sentence that matches each problem type.
