WHY: Purpose of Lesson: The purpose of this lesson is for the students to review the concepts of multiplication that they have been learning for the past few weeks. They will be reviewing the concepts of prime factorization, exponents, estimating, rounding, multiplication strategies, and multi-digit multiplication of up to three digit by two digit numbers. This lesson will serve as a review for the students before taking their unit test on multiplication. Common Core State Standards: • CCSS.MATH.CONTENT.5.NBT.A.2: Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10. • CCSS.MATH.CONTENT.5.NBT.B.5: Fluently multiply multi-digit whole numbers using the standard algorithm. Goals/Objectives of Lesson: What do you hope for/expect? • Students will be able to demonstrate their understanding of prime factorization, exponents, estimating, and multi-digit multiplication strategies by completing a review packet with the teacher. • Students will complete problems in their review packet independently after reviewing with the teacher; students will complete problems on prime factorization, exponents, estimating, and multi-digit multiplication strategies. • Students will work in pairs to play a multi-digit (2 digit by 2 digit and extension 3 digit by 2 digit) multiplication
