Adding Fractions with Different Denominators

Course Module

Tanya McDaniel

SLM521

Goals-

Students will examine a set of online links that are developed to enhance their knowledge of mathematical concepts. Student will use and develop strategies to solve math problems.

Overview-

When I was in school I always disliked the days my teacher would stand up in front of the class for what seemed like hours and explain a concept to me. Maybe my teacher thought that each time he repeated the explanation, I would retrieve the information. If you are like me in anyway, I like to study and learn math through visual and physical means. I can study a visual example and can demonstrate how to solve a math problem. The internet has a wide range of tutorials and online examples that explain mathematical concepts, in such a way that you can understand. You will get a chance to examine several websites that explain how to add fractions with different denominators. You will use these websites to create your own explanation and example on how to add fractions with different denominators.

Reading-

View the links that explain how to solve adding fractions with different denominators. Study the examples and decide which site you would pick as having the best example. The following questions should help guide your decision:

How do the graphics help me to understand how to solve problems with fractions?

How does the arrangement of the steps help me to understand how to solve problems with fractions?

Do the steps use language that I can understand?
