This product is a collection of worksheets that have students use pictures of base ten blocks to add 3 digit numbers with regrouping of either the ones place, tens place or both. Using manipulatives and drawings helps students build a deep, conceptual understanding of mathematics.
There are 4 pages of pre-made problems, 1 page of a blank template that you can draw your own problems, and 1 page of word problems.
They can be used for classwork, homework, assessments, and practice.
The product was designed for second and third graders, but first graders could use them as well because they are concrete representations.
