Description
This is an interactive web-based resource that challenges students to factor numbers by illustrating on a graph the dimensions of a square that has the area of the number they are trying to factor.
Factors are numbers that when multiplied together form a unique product. For example, 2 factors of 15 are 3 and 5 because 3 x 5 = 15. Every number has at least 2 factors, 1 and the number since 1 multiplied by any number is itself (though when finding the factors of 1, those two are the same number). A number that only has two factors, one and itself, is called a prime number. However, some numbers have many factors. For example, the factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.
Students can use the Exploration Questions to guide their investigations.
