This number sense lesson focuses on multiplying decimal numbers. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students multiply the bottom factor with each digit of the top factor, regrouping if needed. Then, they count the total number of decimal places in the two factors and place a decimal in the product that many places to the left. In addition to the lesson, there are four pages of Independent Practice and Periodic Reviews with questions modeled after current adaptive testing items.
