Number Triad Fluency Flashcard

Front

What does it mean for a number to be 'closer' to another number?

Back

A number is 'closer' to another number if the difference between them is smaller than the difference between the first number and any other number being compared.

Front

How do you determine if a number is exactly in between two other numbers?

Back

A number is exactly in between two other numbers if it is the average of those two numbers. For example, the number in between 25 and 125 is (25 + 125) / 2 = 75.

Front

What is the midpoint of two numbers?

Back

The midpoint is the value that is halfway between two numbers. It can be found by adding the two numbers together and dividing by 2.

Front

If a number is 60, how do you find out if it is closer to 25 or 125?

Back

Calculate the difference: |60 - 25| = 35 and |60 - 125| = 65. Since 35 is smaller, 60 is closer to 25.

Front

What is the difference between two numbers?

Back

The difference is the result of subtracting one number from another. For example, the difference between 200 and 0 is 200.

Front

How can you tell if a number is closer to 0 or a larger number, like 600?

Back

Compare the differences: find |number - 0| and |number - 600|. The smaller difference indicates which number it is closer to.

Front

What does it mean for a number to be 'exactly in between' two other numbers?

Back

It means that the number is equidistant from both numbers, meaning the distance to each number is the same.

Front

If 300 is compared to 0 and 400, how do you find out which it is closer to?

Back

Calculate the differences: |300 - 0| = 300 and |300 - 400| = 100. Since 100 is smaller, 300 is closer to 400.

Front

What is a number line?

Back

A number line is a straight line with numbers placed at equal intervals along its length, used to represent numbers visually.

Front

How do you find the average of two numbers?

Back

Add the two numbers together and divide by 2. For example, the average of 10 and 20 is (10 + 20) / 2 = 15.
