Description
Exercise Name: GCF and LCM word problems
Math Missions: 6th grade (U.S.) Math Mission, Pre-algebra Math Mission, Mathematics I Math Mission
Types of Problems: 2

The GCF and LCM word problems exercise appears under the 6th grade (U.S.) Math Mission, Pre-algebra Math Mission and Mathematics I Math Mission. This exercise has word problems that concentrate on finding the greatest common factor and least common multiple of numbers

Types of Problems

There are two types of problems in this exercise:

  1. Least common multiple word problem: This problem provides a situation where the least common multiple is the solution to a story problem. The user is asked to find the solution and write it in the space provided.
    Lagwp1

    Least common multiple word problem

  2. Greatest common factor word problem: This problem provides a situation where the greatest common factor is the solution to a story problem. The user is asked to find the solution and write it in the space provided.
    Lagwp2

    Greatest common factor word problem

Strategies

This exercise is easy to get accuracy badges because the types of situations in the stories repeat often. This also makes the speed badges easy as it is possible to recognize the type and immediately proceed to calculate the answer.

  1. The LCM type problems involve shopping for smallest possible number of hot dogs....(and others).
  2. The GCF type problems involve splitting a group of objects into smaller collections...(and others).

Real-life Applications

  1. Hot dogs and buns are an example of GCF and LCM in real life. For example, LCM can be used to solve this problem: "Hot dogs come in packages of 10, while rolls come in either 8 or 12. What's the smallest number of each one has to buy to have the same number of each?".
