Focus: Applications of Operations with Rational Numbers

The student will solve single-step and multistep practical problems involving addition, subtraction, multiplication, and division of decimals. 
Essential Knowledge and Skills
  • Solve single-step and multistep practical problems involving addition, subtraction, multiplication and division with decimals expressed to thousandths with no more than two operations.
Essential Understandings
  • What is the role of estimation in solving problems? Estimation gives a reasonable solution to a problem when an exact answer is not required. If an exact answer is required, estimation allows you to know if the calculated answer is reasonable.

  1. Multiplying Decimals (Area Model): Model the product of two decimals by finding the area of a rectangle. Estimate the area of the rectangle first. Then break the rectangle into several pieces and find the area of each piece (partial product). Add these areas together to find the whole area (product).
  2. Multiplying with Decimals: Multiply two decimals using a dynamic area model. On a grid, shade the region with width equal to one of the decimals and height equal to the other decimal and find the area of the region.
  3. Sums and Differences with Decimals: Find the sum or difference of two decimal numbers using area models. Find the decimals and their sum or difference on a number line.
