## Lesson: Multiplication by Two-Digit Numbers

Developing the Concept

Now that your students have created their own multiplication fact chart and acquired an initial understanding of using the Distributive Property to solve multiplication problems involving multiplying by one-digit numbers, it is time to expand their understanding by having them use the Distributive Property to multiply by two-digit numbers.

**Materials:** model multiplication fact charts from the first lesson.

**Preparation:** Post your model multiplication fact chart where students can see it.

**Wrap-Up and Assessment Hints**

Create several completely solved multiplication problems, including those with money amounts, that show the algorithm with some missing numbers (see below). Ask students to fill in the missing numbers. This activity will encourage your students to slow down and think about each step in the multiplication process.
