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.

Are You Teaching How to Estimate the Sums?

Fern Smith's Classroom Ideas Rounding to Estimate the Sum Task Cards, Center Games and Color By Code Printables at TeacherspayTeachers, TpT.
 Estimate the Sums
A quick way to estimate the sum of two numbers is to round each number and then add the rounded numbers. {See yesterday's post for help on rounding.} It is likely that this won't be the exact answer but it may be close enough for some purposes. Students need this mental math not only for future math classes and math procedures, but it is also a life skill. Were you over charged at the furniture store? Did you receive the correct amount of change back from the waitress? Problem solving extends to all aspects of their world.

Tips to introduce your lesson...
How to estimate a sum by rounding:
  • Round each number in the problem.
  • Add the rounded numbers together, mental math is even better.
More reasons WHY you would use rounding to estimate the sum:
  • Check to see if you have about enough money to buy something.
  • Get a ball park idea if they have a correct answer to a problem. Is 500 an intelligent answer for 23 + 31?
