Wordless Wednesday

Today I'm linking up with Miss DeCarbo for Wordless Wednesday.  

Here's my picture for the week!

We've been using these work mats for regrouping and my kids are rocking it... they really get the concept behind regrouping and I couldn't be prouder!!  One of my kiddos said to me "Regrouping is hard but it's a lot of FUN!"  My teacher heart melted!!  I can't wait to hear what you use for regrouping!

What materials do you use to introduce and practice regrouping?
