Step one toward the standard multiplication algorithm
Area model multiplication – also called open array multiplication – is an important step in the mastery of the standard algorithm. In this packet you'll find a PowerPoint to show your students and six worksheets that will guide them through understanding this method.

The worksheets include single-digit times two-digit problems, to double-digit times double-digit problems…story problems, too! Of course I provide a complete answer key.
“What a student-friendly/user-friendly resource. A great tool for helping students understand and apply the area model. Thanks.” ~Eric F
The worksheets include a gradual-release, step-by-step process – perfect for encouraging independent mastery of open array multiplication.
Common Core Focus: Math
- Measurement and Data CCSS.Math.Content.3.MD.C.7b Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.
- Measurement and Data CCSS.Math.Content.4.MD.A.3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
