Decomposing Numbers

Yesterday, we began decomposing numbers using place value to help them understand that numbers can be decomposed in many ways to make it easier for computation.  

Students began with a card that  contained a place value problem on it.

Students used base tens blocks to build the numbers.  This process involved exchanging base tens out for hundreds, ones for tens, etc.  We spent two days working on this concept to allow students time to "dig deep" into their learning.
