Content: To gather information on this topic, visit the following web sites
Name of site: Ratios and Proportions Distance, Rate and Time
Brief description of site This site gives a description of distance, rate and time problems, examples, and has interactive questions for the students to answer.
Name of site: Problem Solving: Distance, Rate and Time
Brief description of site This site provides an interactive graphical/visual way to solve a distance, rate and time problem. It also shows how to solve the problem using formulas. The students just need to follow the directions for the graphical method. They can then enter in different information for distance, speeds of each car, and if the cars are traveling in opposite or same directions.
Name of site: Distance, Speed and Time
Brief description of site This site has three different categories of interactive problems that the students need to complete. Their work must be written out on the back of this sheet where they solve the problem and then they can check their answer on the website. They must do three problems from each category, they can do more if they wish.
Assessment/Evaluation:
The students’ answers to the learning web will be collected as will the problems they completed with the learning web. The students will have homework which we will go over the next day in class. If there is a projector and computer hookup in the classroom, the website with the graphical solving tool can be pulled up and used to go over any problems from the homework. The student who has the question can come up to the computer and enter in the correct information and the class can see visually how it is solved and then figure out how to solve the problem with the formula.
Homework:
There will be homework assigned from a worksheet with these types of word problems.
