## Description

Help students to develop a conceptual understanding of factors, multiples, comparing numbers, and multiplication of multi-digit numbers with this multiplication unit!

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

The multi-digit multiplication resource includes four weeks of math instruction with detailed and easy to follow lesson plans. The hands-on lessons are designed to give students a solid foundation with factors and multiples, prime and composite numbers, multiplication word problems, and multiplicative comparison. The other emphasis of the unit is multiplying 2-digit, 3-digit, and 4-digit numbers by 1-digit numbers, as well as multiplying 2-digit numbers by 2-digit numbers. Students use area models and partial product to solve these multi-digit problems.

In this multiplication unit you will find highly engaging and relevant math activities that can be taught in any math class.

### 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.
