Current Unit: Using Place Value to Add and Subtract
Students are:
*Learning how place value understanding can support more efficient strategies for multi-digit addition and subtraction.
Big Ideas in the Unit:
*Subtraction can be thought of as both removal and difference
*Addition and subtraction have an inverse relationship
By the end of the unit, students will be introduced to:
*Compare and order numbers to 1,000
*Use addition and subtraction strategies based on place value, properties of operations, and/or the relationship between addition and subtraction to 1,000 accurately and efficiently
*Explain why addition and subtraction strategies work
