EASYTEACHING.NET

Overview:

This worksheet extends the double-double strategy to solve larger multiplication sums. Students learn to apply the strategy to bigger numbers for more efficient problem solving. Designed for middle years students.

Learning Objectives:

Apply the double-double strategy to solve larger multiplication sums.
Strengthen mental math skills for more complex multiplication problems.
Develop problem-solving techniques for multiplying by 4 with larger numbers.

How the Activity Works:

Students use the double-double strategy to solve larger multiplication problems, such as 4x30 or 4x150. They first double the number, then double it again. For example, to solve 4x30, students double 30 to get 60, then double 60 to get 120. This strategy helps students handle more complex multiplication problems and improves their ability to solve them mentally.
