4th Grade Math – Multiplication Unit

Description

Help your students to develop a conceptual understanding of factors, multiples, comparing numbers, and multiplication of large numbers with this four week multiplication unit! Fourth Grade Math Unit 3

This individual unit is also available in my 4th Grade Math Bundle.

This product includes four weeks of math instruction that is written in an easy to follow format. The lessons are written to give students a solid foundation in finding factors and multiples of numbers, multiplicative comparison, and multiplying 2-digit, 3-digit, and 4-digit numbers by 1-digit numbers, as well as multiplying 2-digit by 2-digit numbers. Students will learn to multiply larger numbers through box models, area models, and partial product. In this unit you will find performance tasks to conceptually teach new skills through the workshop model, as well as work station activities and games for review.

Standards Taught

4.OA.1-Interpret a multiplication equation as a comparison, e.g., interpret 35= 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.

4.OA.2. Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison

4.OA.4. Find all factor pairs for a whole number in the range 1–100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1–100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1–100 is prime or composite.

4.NBT.5. Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
