This resource has the students adding together 3 digit numbers, using the partial product method. The studnts will need to take apart each addend based on their expanded form place value and add together those place values. They will then add together those 3 numbers to answer the equation. There are two examples at the top of the first page for the students to reference. The problems get harder as the pages go along, getting into 4 digit answers. This can be used as a whole group lesson, small group work or homework.
