Description: The "All About Ratios" activities are designed to introduce ratios in a concept-building way. The activities can be done on computers with Internet access or be printed. The author suggests that pairs of students work together at the computer talking to each other about the activities. Exercises and quizzes are checked on-line, and teachers can record the results. Practice answers are hidden under a tab so that students can easily check their answers. Problem solving answers are submitted and both the students' and the correct answer are returned. Teachers can circulate and record the students' responses.

Comment:This is a good way to get the whole class focused on how ratios describe a number of objects compared to another amount of objects.
