This summative addition (with rounding, mental math, estimation, and word problems) is intended for third graders. Please know I set up my assessments based on the standards based reporting system. There is a heavy emphasis on looking at each math skill vs. the percentage!
There are two versions to meet the needs of your learners. Test A includes more problems with a challenge page while Test B has fewer problems without a challenge page.
*Note: The "challenge" page is intended for higher/advanced math students. My school follows the standards based report cards. Therefore, I like to provide this section for my advanced mathematicians as a form of data/proof they can perform above grade level expectations.
