Question

Write the steps for how to use a number line to multiple a 2-digit number by 20. Give an example.

Answer 1

In a time long long ago, people were able to multiply a number by 20 in their heads.

To use a number line to multiply a 2-digit number by 20, follow these steps:

Step 1: Draw a number line with increments of 20. Label the starting point as 0, the first increment as 20, the second increment as 40, and so on.

Step 2: Place a dot on the appropriate number on the number line that corresponds to the given 2-digit number. For example, if the given number is 35, place a dot on the number 35 on the number line.

Step 3: Count the number of increments from the starting point (0) to the dot you placed. Each increment represents 20. For example, if the dot is placed on 35, count the number of increments to reach 35, which in this case is 2.

Step 4: Multiply the number of increments by 20. In this example, since there are 2 increments, multiply 2 by 20 to get the result, which is 40.

Therefore, the result of multiplying a 2-digit number, such as 35, by 20 using a number line is 40.

Note: This method can be used for any 2-digit number by simply adjusting the placement of the dot on the number line.
