Apparently the math standards for Virginia are up for revision. You may want to take a look:
Standards of Learning
Here are the proposed changes to 3rd Grade:
-addition and subtraction fact families (moved to 2nd grade)
+naming, writing and representing improper fractions
-recalling multiplication facts (moved to 4th grade)
+learning multiplication facts though 10's only
-weight and mass (moved to 4th grade)
+defining, naming, combining and subdividing polygons (moved from 4th grade)
-identifying, describing, comparing and contrasting plane and solid shapes (moved to 4th grade)
-line plots (moved to 5th grade)
I personally love the changes they are proposing, it seems like the curriculum is becoming more developmentally appropriate.
