Although it will not answer all of your questions, we are hoping this will help bridge the gap between the "old" way of learning math and the "new" way of learning math at the 4th grade level.
Take a look at this video: Why is Math Different Now?
Above you will find a tab specific to each unit of math study. Within each tab you will find things like videos, pictures and tutorials we use in the classroom that you or your student can access at any time when assistance is needed.
Please be advised that this blog is a work in progress, but we are confident in the fact that it should be a helpful tool for you and your student.
Enjoy!
