PRODUCT DESCRIPTION

Teaching how to count atoms in chemical formulas is made easier with this power point and foldable. Foldables are a great way for my students to categorize and process formulas, and I thank Dinah Zike for inventing them. However, in my large classes of 35-40, it is easy for 5 or 10 students to fall behind. So, a foldable with a power point, on the PSEC strategy helps my classes explore the mathematics of chemical formulas. Each student makes their own foldable.

There are several introduction slides with water and a snowman (this is the time of year when we are looking for snow). After the introduction, you pass out three pieces of paper, and show students how to make a "Layered-Look" book. (It's worth the paper, give a classroom participation grade, too). Each student is allowed to use their own foldable on quizzes, and tests, too. Include a title, and their name. Next, have your classroom helper advance the power point to a slide with a cougar. It will be the first part of PSEC, parenthesis. This cougar let's the students know they must copy what is on the slide. Next, they decide on the number of atoms, and by advancing the slide, the answer is revealed. Wait for the class to finish their foldable page, then advance to the next PSEC strategy (subscript). Continue until all slides are finished. This may take two or three days with some classes, but that's ok.

Note: I show a completed book to the class before they begin. I make it by printing off the power point. I then cut and paste the parts into the foldable. I also tape it onto the board, or share it with students who fall behind. If a student is absent, giving them the foldable to copy is easy make-up work. I also make several foldables with my first few classes, and then show each subsequent class what the blank foldable should look like. If there are special students who need more help, the foldables started go to them. If there is a talented student who finished quickly, that student(s) helps others having difficulty, or may make blank "layered look" foldables.

This may sound complicated, but its an easy, effective lesson, and if an observer comes knocking, your observation score should be great!
