In regards to Math Expressions, read this message for using the workbooks:
As an extra resource to support your child at home in math, I sent home volume 1 of the students math workbook. (Volume 2 will come home in January). Please keep this book at home for the rest of the year. I will not be using those pages in class, so feel free to work through the pages when you see your child could use extra review in certain subjects. Do be aware that even though your child is taking the 4th grade SOL this year and using similar resources as the other 4th grade math students, TAG math follows a different order for the curriculum. The order of pages in the workbook might not exactly correspond to the current lesson in class.
