What is a factor for teaching the 4s multiplication using the doubling method?

• A. Doubling Once
• B. Doubling Twice
• C. Finding Corresponding 10s Fact
• D. Adding Another Factor

Answer: (B)

The answer relates to the technique of teaching multiplication by leveraging the concept of doubling numbers. When teaching the 4s multiplication using the doubling method, the idea is to show students that multiplication by 4 can be understood as doubling a number twice. For instance, if you want to compute 4 times 3, you can first double 3 to get 6 (which is 3 x 2) and then double that result to get 12 (which is 6 x 2). Hence, 4 times 3 equals 12, and this method highlights the connection between multiplication and addition through repeated doubling. This doubling method is particularly effective in helping students visualize and understand the concept of multiplication as repetitive addition. Each doubling reveals a straightforward path to the answer, reinforcing the relationship between these mathematical operations.
