Product Description
Gradual-release worksheets and a PowerPoint presentation make introducing partial-product multiplication easy! The partial product multiplication algorithm is a foundational piece of math in the fourth and fifth grade. This is where we move from an area model for multiplication made of decomposed numbers to a traditional algorithm.

Check the preview to see every page of the packet, and look below for a link to view a sample of the PowerPoint.

The partial product algorithm is a way for students to deepen their understanding of place value while multiplying. Once this is mastered, students are ready for the standard algorithm for multiplication.

• A PowerPoint presentation that walks students through the Partial Product Algorithm. It provides step-by-step models as well as practice slides. I use this in my class during Whiteboard Math so students can follow along and practice every step.

• Three PDF worksheets with 12 items each:

~ Worksheet 1 has simpler numbers to multiply and maintains all columns and rows to support students as they learn the pattern for solving these multiplication algorithms.

~ Worksheet 2 is the same as worksheet 1 except the numbers are a little more challenging.

~ Worksheet 3 removes some of the scaffolds for students as they grow toward mastery.

My students always enjoy partial product multiplication because it makes sense to them. They have mastered their basic facts and they are ready to tackle larger numbers. Kids like following a pattern and partial product multiplication algorithms fill that bill!
