## Reflection: Intervention and Extension 3-Digit Addition with 'Trading' - Section 1: Lesson Intro

I find that students come to me with different levels of understanding of place value. Although many understand that there are different places, they have less structure in recording their work and ensuring the place value is correct. At the start of the year, I begin to develop a structural understanding of place value. As I intervene with students who struggle, we can use that structure to place numbers on a place value chart. For those students ready to move on to larger numbers, they also have a structure for ensuring the place value is correct. Place value is so fundamental to mathematical thinking, so that although some of my students may not need all of the structure I put into place at the start, it is worthy of the reinforcement.

## Big Idea: The building blocks to build our foundation! Place value blocks represent my hundreds, tens and ones and can be used to help me solve 3 digit addition problems.
