[Part Part Whole addition/subtraction workmat]

When I introduce addition (even as early as the first few days of school when we do the "houses" for each number, I have my munchkins use these workmats.  It's a great visual and gives them the math talk that they need to be familiar with.  I've used the divided plates, but have found more success with this little workmat.  I give each student one workmat, in a sheet protector, to be stored in their desks to use when they need them.  These are great for those kiddos that still need a visual representation of a number sentence in January because they can pull them out of their desks as needed and can be used for addition and subtraction.  :)
