This is just a quick check assessment for third graders, but could probably be used for lower kids.
-rounding to nearest hundred
-rounding to nearest ten
-adding within 1,000
-subtracting within 1,000
-perimeter and area
-identifying regular shapes (triangle, hexagon, quadrilateral, pentagon, octagon, and decagon)
NOTE: You need to draw the hands on the clocks yourself. I did this so you can pick if you want to assess to five minutes or to the nearest minute.
