Here is a list of math functions your third grader should know by the time they finish the year. The first group of items are the most important things for your third grader to know and they should be practiced on a daily basis. The remaining items in can be taught along with the other lessons.
By the end of the third grade, a student must be able to do the following problems effortlessly.
- Addition and subtraction facts to 25
