Are You Teaching How to Use the Break Apart Strategy For Place Value?



The Break Apart Strategy For Place Value

Breaking a 2-digit or larger number apart, or ungrouping the number, is a strategy that helps students see the value in place value. The tens place is not just a 4. It’s value is 40 or 4 tens. The more mental math tips that students have in their tool kit of skills, the easiest each step of the harder math skills become.


One of the best ways to each this strategy is with base ten blocks. I teach my students a "banking method" I'm taking a ten and I'm going to the bank and returning with 10 ones. It is a lot of fun to model it in the beginning, taking your ten piece and walking over to another table to trade it out for 10 ones. Later as they are practicing and reviewing this skill by themselves, it is wonderful to hear, "I'm taking these three hundreds to the bank..."

I like base ten blocks that are all one color, that way the students don't get confused with trading "red" for "green" instead of the skill of trading ones for tens. The above picture is a wonderful set at Amazon that are magnetic for your board or an independent center. 


Another great way to practice is with dice, specifically place value dice.


Students can roll their dice at the same time and the winner is the one with highest number. They can play to ten points, or if you have a few minutes before lunch or dismissal, play the lightening round... winner needs two wins. By having the students check each other's dice, there is more mental math going on in a short period of time.

For each unit, I stick to one color to make it easier for the teacher to make, sort and store the lessons each year. For each section of the lesson I try to use the same adorable student clip art. That way, indirectly, the children know the task cards, the color your answers printables and the center games are all focusing on the same skill.

Four center game pages in color AND
Four center game printable pages in black and white to use as a Make and Take Math Center!
