This is one piece of a larger review that we are in the process of creating. What you get in this file is 9 "Work it Out Wednesday" templates that cover standards 4OA.1, 4OA.2, 4OA.3, 4NBT.1, 4NBT.2 and 4NBT.3. Designed to be used as handouts for the students or projected during math recursive review/ warm up/ or morning work times. This will keep your students practicing the standards even as you "cover" other standards/concepts during your math lessons. We have carefully planned and sequenced the materials to get increasingly harder and also to expose students to all different types of problems that might hit the intent of the standard. If you try this and like it....you can watch for the next 9 weeks of Work it Out Wednesday, we will post them as "2nd 9 Weeks." Also check out "Measurement Monday" "2-D Tuesday" "Think Algebra Thursday" and "Fraction Friday" to complete your review each week!!
