Product Description
An easy step by step unit plan of 4-5 days (one hour of math class per day) that has students learning how to solve for an unknown in a multiplication equation--Common Core Standard 4.OA.A.2--by starting with the multiplication table and the concept of a balanced multiplication equation, and ending with the ability to interpret and demonstrate the multiplication equation with an unknown number as a verbal representation of a real life comparison. Students learn from modeling, guided practice, a motivating group activity, and by teaching others. An assessment for Standard 4.OA.A.2 and the focus of this unit is included. Students will:
1. Learn how to solve for an unknown number in a multiplication equation, based on the multiplication table from 1x to 12x
2. Practice their skills solving these problems by solving and creating multiplication equations with unknowns
3. Learn how to explain a multiplication equation having an unknown number as a verbal statement of comparison
4. Practice their skills explaining a multiplication equation having an unknown number as a verbal statement of comparison

Key vocabulary, concepts, and questions include: Multiplication, equation, balanced equation, factor, product, solving for an unknown in an equation, substitute, substitution, (multiplicative) comparison
Materials in this packet contain everything you need for Instruction, Guided Practice, Individual Practice, Group Activities, and Assessment of Concept Attainment for the unit, including Instructional Presentation Materials for the Teacher, Student Worksheets, a step by step guide for the Teacher, and a final assessment covering the material taught.
The procedure delineates how, and the order in which, I use each of the teacher and student pages I created to build toward the understanding of Common Core Standard 4.OA.A.2 Multiply to solve word problems involving multiplicative comparison, e.g. by using equations with a symbol for the unknown number to represent the problem. A final assessment is included on p. 14.
