This Part-Part-Whole Write ‘N Wipe Mat can be used to help students learn the critically important relationship between addition and subtraction.
Making use of multiple representations allows students to access this inverse relationship in several ways – through the use of physical modeling with real-life objects, through the use of numbers in a number sentence (both addition and subtraction), and through the use of visual modeling with the part-part-whole graphic. In these ways, students can build on their prior knowledge of addition in order to develop their understanding of subtraction.
I use Write ‘N Wipe mats with students by placing them in a sheet protector, plastic pocket, or job ticket holder. You can purchase any of these items from a school or office supply store or site.
Write 'N Wipe mats make great morning work, math center tasks, or tools for instruction.
