A few years ago, the Douglas School District adopted the Investigations Math curriculum. Through that adoption process, there have been a few frustration moments with the Math strategies being taught. The new strategies that are being taught help students to learn number sense more in-depth which leads to better mental Math skills. I know it is frustrating, but I have honestly seen a huge improvement in my students’ mental Math capabilities. (Many of them can solve the problem mentally faster than I can.) Therefore, in order to help your child at home with their homework, I have created tutorial videos that explain how to solve Addition, Subtraction, Multiplication, and Division problems using the new strategies. I hope these help you at home!
