THIRD GRADE MATH RESOURCES (UNITS 301-305)
Ready to start third grade math?  NFC Academy has resources for you to use in addition to those in your curriculum. This first semester of 3rd grade math resources has worksheets to use for more practice and videos to supplement instruction information. 

These are available to our homeschool families to use if they are needed. Some worksheets may be found multiple times in your resources since you may select to use them for one lesson or the other and perhaps more than one time.  Just click on the resources below for your use. 
Click on each listing you want to use. This text color of the "red shade" indicates a video or online resource and the "green shade" is a worksheet to download.  Remember math is generally best solved by following the steps in a process.  Sometimes a short-cut is available, but math assignments are typically best completed using paper and pencil to follow the steps to arrive at the correct answer and show your work.

The parent will decide how many of the resources to use...they are there for your use as works best for you as the teacher.

NFC Academy thanks Math Salamanders, K5 Learning, Common Core sheets, Khan Academy, Mathispower4u and Miaacademy Learning Channel  allowing NFC Academy to research their sites and use material for our parents. ​​Visit their website for more helps that you may want to use. ​
