A number story is a short story that illustrates a math equation, making it easier for young students to understand the equation involved. For example, the equation 5+2=7 can be told as a story about five birds sitting on a tree that were joined by two more birds.
Know MoreTeachers sometimes ask students to describe simple equations in the form of a number story. Besides increasing the child's understanding of the equation and encouraging creativity, the activity can also be used to improve a child's drawing skills by illustrating the story. Number stories are typically written or drawn for simple arithmetic operations such as addition and subtraction. Some examples of number stories include:
In mathematics, the term "interval" usually refers to a statistical confidence interval. Confidence intervals describe the likelihood of a statistical estimate being correct. Higher confidence intervals mean better chances that the estimate is correct, while lower confidence intervals mean better chances that the estimate is incorrect or flawed.
Full Answer >In mathematics, a prime number is any whole number greater than one that has no positive factors other than one and itself. For example, the number 17 is prime, because its only factors are one and 17.
Full Answer >Prime numbers are important in mathematics because they function as indivisible units and serve as the foundation of several mathematical disciplines. Because a prime number is a natural number greater than 1 that can only be divided by itself and 1, all non-prime numbers, which are called composite numbers, can be factored into a unique set of prime numbers. Computer security programs and cryptology are two fields that have made use of prime numbers to code and decode sensitive information.
Full Answer >In mathematics, the short word form is created by writing a large number using a combination of numbers and words. For instance, the short word form of 785,000 is 785 thousand.
