The first instance of Divisibility 0.5 is under the 4th grade (U.S.) Math Mission. This exercise practices the vocabulary words of multiple and factor and strengthens the relationship between them.

Types of Problems

There are two types of problems in this exercise:

  1. Find the multiple: This problem asks the student to select which of the numbers is a multiple of a given number.
    Ofmult

    Find the multiple

  2. Find the factor: This problem asks the student to select which of the numbers is a factor of a given number.
    Offact

    Find the factor

Strategies

This exercise is easy to get accuracy and speed badges because the problems are predictable, easy to read and fast to answer.

  1. The questions are multiple choice so there is only one correct answer. Once you find it, don't bother checking the other possibilities.
  2. Research indicates that there is no problem in which you are given multiples and factors. Factor questions have numbers that are all smaller than the given number and the multiple problems are all larger. Therefore you can use the list of numbers to infer whether you need a multiple or a factor.

Real-life Applications

  1. Choreographers need to be able to divide the piece they want to perform, into smaller pieces so that everyone will be able to do and give their best, whether they dance or choreograph an orchestra. In the end of the day they need to flow together in harmony and they will use division to accomplish that.
