Fractions cut and copy 2

The  exercise appears under the Arithmetic Math Mission and Pre-algebra Math Mission. This exercise has a unique tool that allows users to better identify and understand the relationships among fractions.

Types of Problems
There is one type of problem in this exercise:


 * 1) Cut and create the fractions: This problem has a bar drawn that has a certain given length. The student is asked to cut this initial bar into pieces, and then tell how many of those pieces are needed to make two additional bars of specific lengths.Fcac2-1.png

Strategies
Knowledge of fractions and the processes to create common denominators is important to ensure success on this exercise.


 * 1) The first step should be to determine the common denominator of the fractions bars that are going to be created.
 * 2) After this, the original given bar should be cut into enough piece to create a unit of those fractions.
 * 3) Then the fractions bars can be created by providing enough blocks to make each fraction in the common denominator form.
 * 4) When several blocks need to be provided, rapid clicking can sometimes miss one copy, so it is important to continue to look at the picture and make sure that it is correct.

Real-life Applications

 * 1) Fractions can be a source of weakness for many students but are important in measurement, science and economics. The strengthening of fractions via geometric models will increase proficiency with fractions.
