Doubles doubles we can subtract doubles!!!

We clearly love our dice! 

 

Today we began working on doubles subtraction.  The first step to this was to review doubles addition.  We listened and danced to our doubles addition song as well as a doubles addition and subtraction brainpop video.  Once we reviewed doubles addition we explored how doubles addition can be flipped to make doubles subtraction EASY!  We then used our dice and rolled them to get a number.  Once they got a number they used doubles addition to make an equation.  Then they flipped it and made a doubles subtraction problem. 

 

For example:

6+6=12

12-6=6

 

They all did a great job and rocked out on the doubles subtraction!!!

 

Who knew how awesome dice were!!!

So while on fall break I found some awesome dice!  They are clear dice and inside the dice is another smaller dice.  I'm quite disappointed in myself for purchasing only 10 of them but they are a HUGE hit!  We've used them for both addition and subtraction games.  Today we worked on subtraction with partners.  They partnered with their neighbor and took turns rolling the dice and collecting the numbers from the double dice to write the subtraction equation.  They had to identify the larger and the smaller number and make sure they put the larger number first (no negative numbers here)!  The hands on practice has really made us all subtraction experts and as always games make any concept more engaging and fun!
