Multiplication Practice Problems

Mrs. Lamorne teaches fifth graders about the standard algorithm for multiplying one-digit and multi-digit numbers. The lesson includes a comparison of partial products and the standard algorithm, followed by practice problems. Students learn to compose new units and apply the standard algorithm effectively.

What is the main focus of today's lesson?

• Division of decimals

• Subtraction of fractions

• Multiplication using the standard algorithm

• Addition of multi-digit numbers
