Brush up on your multiplication, division, and factoring skills with this interactive multiplication chart. Three levels and timed or untimed options are available.

This activity was used in addition to the EngageNY.org Grade 4 Mathematics Module 3, Topic H, Lesson 36 . This lesson was used with a tier 3 fourth grade math intervention group to help students visualize and build understanding of multiplying a 2 digit by 2 digit number using partial products. I modified the lesson by designing a worksheet that would help the students use an area model to visually represent the partial products. My students were proficient in expanded notation, however, they needed the visual representation to build the understanding of where the partial products came from and represented. This helped them move from a pictorial representation to abstract representation. To help solidify place value, it was helpful to have the student shade, in different colors, the rectangle that represents the ones, tens, and hundreds. We also continued to write out the expressions used to find each partial product.
