This is one piece of a larger review that we are in the process of creating. What you get in this file is 9 "Think Algebra Thursday" templates that cover standards 4NBT.4, 4NBT.5, 4NBT6 and 4OA.4 and 4OA.5. 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. This particular set also introduces the beginning concepts of long division (starting at Week 8) using hands-on materials, pictorial models and guiding questions. If you try this and like it....you can watch for the next 9 weeks of Think Algebra Thursday, we will post them as "2nd 9 Weeks." Also check out "Measurement Monday" "2-D Tuesday" "Work it Out Wednesday" and "Fraction Friday" to complete your review each week!!
