We've begun working with fractions. And I mean really working with fractions. We've learned how to add and subtract like and unlike fractions as well as mixed numbers. Now we are moving on to multiplying and dividing fractions. We, of course, are working with these functions in lots of word problems so that students can show that they understand how to apply the algorithms. Check out the recent addition to our Challenges page!
The concept of cross-simplifying can sometimes be daunting, although I've noticed that once students grasp the concept, they work comfortably with it. If you are finding that your student is not quite understanding how to use cross-simplifying, I would recommend some of the online tutorials that are available. Math in Focus offers a 5-minute tutorial on this topic. Students can access this by logging into their Math in Focus account and going to the Library to look for the Interactivities. (If you need reminder instructions on how to do this, please let me know in a separate email.) I also found that Kahn Academy has some good tutorials that pretty much match Math in Focus methodology for multiplying fractions.
In real life, especially with Thanksgiving and all of its food, share with your students how you use multiplying all the time in cooking as you double and halve recipes.
