This is a review of the 6 common core standards found in Number and Operations Base 10 domain for fourth grade.
Every day there are 6 questions which correlate with the six 4th grade base 10 standards. Every problem has the standard it is covering posted above it. This will allow the teacher to be able to assess what area(s) may need more review. They are also set daily in the same order according to the numbers set under the domain in the common core standards (for example problem 4 will always be add and subtract multi-digit whole numbers).
This can be used for daily homework or seat work when students enter your room.
You can use it for a week long review after you have covered the base 10 domain, culminating in a quiz at the end of the week.
Another idea is to choose a day of the week and give this assignment for 4 weeks on that same day as a continual review. I use this towards the end of the year (Mondays I cover Algebra, Tuesdays are base 10 and so on). These will be updated to my store soon.
When I taught a 4/5 split, I would put the 5th grade review on the other side. This will be uploaded to my store soon.
