Unit: 2 Heather Bundick / Week 14 Monday 11/14/16 Day 1
Domain: Number and Operations in Base Ten / Suggested time/duration: 60 minutes
Standard: MAFS.2.NBT.2.7
Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
MAFS.2.NBT.2.9
Explain why addition and subtraction strategies work, using place value and the properties of operations. / Learning Target(s):
  • use concrete models to add and subtract two 3-digit numbers within 1000.
  • use drawings to add and subtract two 3-digit numbers within 1000.
  • use strategies based on place value to add and subtract two 3-digit numbers within 1000.
  • justify the strategy chosen to solve a problem and explain thinking.
  • apply knowledge of place value and the properties of operation to explain why addition or subtraction strategies work.

Rigor: Conceptual Understanding / SMP(s): 4: Model with mathematics. 6: Attend to precision. 7: Look for and make use of structure.
