With Identify Fractions with Circle Models you can design fractions examples that use circle models to demonstrate the meaning of numerator and denominator.
The denominator tells the number of equal parts that make up a whole. The numerator tells the number of chosen parts. If you input 3 for the numerator and 4 for the denominator you will get a circle that is sectioned into 4 equal parts, 3 of them will be colored(chosen).
You can input any fraction with value a equal to or less than 1. The denominator must be between 0 and 100. Press the <OK> button and the chosen fraction will appear.
On the left is a <SHOW COLOR> check box. Uncheck the box to turn off the red selected part of the circle. This will allow the learner to select the fraction.
Uncheck the <EXPLAIN> check box to turn off the answer and the explanation.
With <SHOW INPUT> unchecked, the numerator and denominator input boxes will act the same as password input boxes so learners will not see the numbers you input.
With <SHOW INPUT> unchecked and <EXPLAIN> unchecked, the student can identify the pictured fraction.
With <SHOW COLOR> unchecked and <EXPLAIN> unchecked, the student can shade the indicated fraction.
Demonstrate numerator with 3/5 and then 4/5. This will show that the fraction will increase in size as the numerator increases.
Demonstrate denominator with 3/5 and then 3/6. This will show that the fraction decreases in size as the denominator increases.
