• Measurement Topic(s) in this Module-- Addition, Subtraction, Number Concepts and Relationships
• Basic Facts Considerations-- During this module, independent work time for students should include purposeful practice of previously learned basic facts of +1, -1, +2, -2, +0, -0. 

Two Weeks • September 30 - October 11

Then, instruction on 2NBT8 should occur so students can make connections to decomposition strategies. Next, add and subtract (2NBT5) using  the specific strategies outlined above.  Finally, work with lessons from 2OA1 (change unknown) for application of addition and subtraction. 
• Measurement Topic(s) in this Module-- Addition, Subtraction, Solve Word Problems
• Basic Facts Considerations-- During this module, independent work time for students should include purposeful practice of previously learned basic facts of add 10, subtract 10, doubles, halves, make 10, subtract from 10, +1, -1, +2, -2, +0, -0.
• Other Notes-- Although 2NBT5 is a computation standard, word problems should provide context during instruction.  Estimating sums and differences should always be included in the math conversation.

One lesson is included for counting coins and bills to $5.00, do not linger here, this is for exposure not mastery. Reserve one day to solve comparison problems involving money (2OA1).  Some instructional time should be used to revisit the basic facts instruction (2OA2) on the strategy of using ten/related subtraction facts (introduced last module).
• Measurement Topic(s) in this Module-- Addition, Subtraction, Measurement and Geometry Concepts, Solves Word Problems
• Basic Facts Considerations-- During this module, independent work time for students should include purposeful practice of previously learned basic facts of using ten/related subtraction facts, add 10, subtract 10, doubles, halves, make 10, subtract from 10, +1, -1, +2, -2, +0, -0

Three Weeks • March 10 - March 28

In this module, students will

• Add and subtract 3-digit numbers using tools, diagrams, and number lines with strategies of Partial Sums (+), Count On (+), Count Back (–), and Think Addition (–) 2.NBT.B.7
• Continue to acquire basic fact strategies for facts that use near doubles and near halves.  2.OA.B.2

Notes About the Module:

• Recommended Timing Guidelines--  The majority of this module should be spent on  adding and subtracting three-digit numbers. (2NBT7) These strategies were taught earlier and can now be revisited and extended to three-digit numbers. Work with partial sums should be limited and instruction should move students toward the more efficient strategy of counting on. Partial sums with 3-digit numbers makes mental computation difficult and inefficient.  Leave a few days toward the end of  the module to work with addition/subtraction problem solving lessons (found on the 2NBT7 page). Some instructional time should be used to revisit the basic facts instruction (2OA2) on the strategy of using near doubles and near halves (introduced last module).
• Measurement Topic(s) in this Module-- Addition, Subtraction
• Other Notes-- Although 2NBT7 is a computation standard, word problems (2OA1) should provide context during instruction.
• Other Notes-- When working with partial sums, connections should be made to the previously taught standard of 2.NBT.B.8 (mentally +/- 10 and 100 from a given number
• Other Notes-- Be aware that some of the 2NBT7 lessons provided will deal with solving money problems within $5.00.  This is a direct connection to addition and subtraction with three-digit numbers.

Be aware that students will receive extensive instruction on adding and subtracting with 3-digit numbers in quarter 1 of 3rd grade.
• Measurement Topic(s) in this Module-- Addition, Subtraction
• Basic Facts Considerations-- During this module, independent work time for students should include purposeful practice of all addition and subtraction basic facts.
