Workshop: Multiplication Strategies
Est. Class Sessions: 3Before the Lesson
This Workshop provides opportunities to review and practice efficient computational and estimation strategies for solving multiplication problems. Prepare to observe and assess students' use of these strategies using the following Expectations:
- E1.
- Demonstrate understanding of the place value concepts and mathematical properties involved in operations with multidigit numbers (e.g., making trades in addition and subtraction, using the distributive property to multiply).
- E2.
- Show connections between models and strategies for multiplication (e.g., demonstrate partial products using a rectangle model for multiplication).
- E4.
- Multiply multidigit numbers using mental math and paper-and-pencil methods (expanded form, rectangle model, all-partials, compact).
- E5.
- Estimate sums, differences, and products.
- E6.
- Choose appropriately from among mental math, estimation, and paper-and-pencil methods to find sums, differences, and products.
- E7.
- Solve multistep problems using addition, subtraction, multiplication, and division.
- E8.
- Use multiplication and division strategies to find the area of rectangles or shapes based on rectangles.
- E9.
- Use multiplication and division strategies to find the volume of boxes.
Students will identify their level of confidence with a particular concept and choose problems from Workshop Menus. See the TIMS Tip for more about Workshop Menus.
Use your own evaluation of students' progress to help guide their choices. Plan to organize the class into partners, small groups, or stations based on the problems chosen from the menus. Students may work with different groups or partners as the Workshop progresses.
