My Favorite Finds #2

Okay y'all, I am keeping it real here when I tell you that I almost hyperventilate when the time comes to teach  3 digit subtraction with regrouping to my 60 RtI babies!  You add in a full moon this week and it is the perfect storm! However, there is a site that has saved me from breathing out of a paper bag for years now!  My RtI and Inclusion kiddos are often very visual and need to truly see how math works. However, staying focused and using base-ten blocks at the same time can be a little or maybe A LOT more than I can expect of them.  So, this presentation is a happy little compromise!  To save you some trial and error and a boat load of time, I made a little tutorial to go with this FABULOUS site.  Click HERE to check it out!  They have TONS of virtual manipulatives, people, TONS, I say! This is how the site looked on my SMARTboard today.

The kids sat in the floor with their question sheet on a clipboard. We built and solved the problems step by step.  It was a magical moment when one baby said, "I finally know what this is all about!" As Junie B. would say, "My eyes got a little bit of wet in them!"  I hope this is helpful to you!  Enjoy!

I would love to hear from you if you give this a try!  

Thanks!

Subtraction with Regrouping Tip and Freebie

Once my sweeties learn to regroup, they start crossing out every number in sight! So, to slow them down and make them think, we added a step to the regrouping process. Before they cross out anything or subtract any number in a multi-digit problem, they have to answer this question: Which has more: top or floor? When they decide, they put a tiny dot beside the larger number. From there, we follow these rules.

1. If the dot is on top, you don't have to stop.

2. If the dot is on the floor, regroup to get more.

3. If the numbers are the same, then zero wins the game.

Placing the dot comes in handy throughout the regrouping process. Our interventions next week will focus on three digit subtraction. So, you just repeat the process for the tens place. Which has more, top or floor? This simple tip has really helped our struggling mathematicians slow down and think it through.
