Multiplication and Skip Counting

Front

What is multiplication in terms of repeated addition?

Back

Multiplication is a mathematical operation that represents the total of adding a number to itself a certain number of times. For example, 4 multiplied by 10 can be expressed as 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4.

Front

What is skip counting?

Back

Skip counting is the process of counting forward by a number other than one. For example, skip counting by 4 means counting 4, 8, 12, 16, etc.

Front

If a student skip counts by 4 starting from 4, what is the 5th number in the sequence?

Back

The 5th number is 20.

Front

What is the formula for finding the nth term in a skip counting sequence?

Back

The nth term can be found using the formula: nth term = starting number + (n-1) * skip count.

Front

What does the equation 10 × 10 × 10 × 10 represent?

Back

This equation represents multiplying 10 by itself four times, which equals 10,000. It cannot be used to find the answer in a skip counting sequence.

Front

How can you express 4 multiplied by 10 using skip counting?

Back

You can express 4 multiplied by 10 as 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, where the 10th number is 40.

Front

What is the difference between multiplication and skip counting?

Back

Multiplication is a single operation that combines groups of equal size, while skip counting is a method of counting that involves adding a fixed number repeatedly.

Front

How do you determine the total when skip counting by a number?

Back

To determine the total when skip counting, multiply the skip count by the number of times you count. For example, skip counting by 4 for 5 times gives 4 × 5 = 20.

Front

What is the significance of the starting number in skip counting?

Back

The starting number is the first number in the sequence and determines the entire sequence of numbers generated by skip counting.

Front

Can skip counting be used to solve multiplication problems?

Back

Yes, skip counting can be used to visualize and solve multiplication problems by representing the multiplication as a series of additions.
