Computation

===//Students compute with rational numbers* expressed in a variety of forms. They solve problems involving ratios, proportions, and percentages.// Many students struggle with fractions. Here you will find five resources that are available to every student, and I have reviewed them personally for you.===


 * [|**Dividing Fractions by Fractions (text with practice)**]** This applet is used to emphasis basic fractions as part of a whole and its' value on a number line. This site provides students with an explanation, examples, and places where the students can continue their learning through games and exploration. **Additional Evaluation and Annotation[[image:http://math.pppst.com/banner_math_ratios_proportions.gif width="567" height="283" align="right"]]

 * [|** Fraction Model**]** Explore different representations for fractions including improper fractions, mixed numbers, decimals, and percentages. Additionally, there are length, area, region, and set models. Adjust numerators and denominators to see how they alter the representations and models. Use the table to keep track of interesting fractions. **Addititional Evaluation and Annotation**=====


 * [|** Free Ride**]** Free ride is an applet that provides understanding of ratios and adding and subtracting fractions. Ratios are explored with the changing of gears in the front and back of the bike. The bike moves forward so much based on the ratio between these two gears. Students are given an opportunity to further their understanding of adding and subtracting fractions as well as see how ratios are related to fractions. Practice may also lead to fluency, but initial it takes problem solving skills. **Additional Evaluation and Annotation**


 * [|** Match the Fraction**]**This applet is used to emphasis basic fractions as part of a whole and it's value on a number line. The students are expected to divide the number line of 1 into slices and select the fraction that is presented. The use of slices and fractional bars promotes understanding fractions as division of a whole number. The denominator determines how many "slices" you break the whole into. **Additional Evaluation and Annotation**


 * [|** Math Baseball**]** FUNBRAIN will give you addition, subtraction, multiplication, and division problems. Enter the answer to the problem correct and you will get to swing. FUNBRAIN will decide if the hit is a single, double, triple, or home run based on the difficulty of the problem. If your answer is wrong, you will get an out. The game is over after three outs. **Additional Evaluation and Annotation**
