Differentiate this resource to meet your needs with the included editable task cards!
You will find these task cards to be a very versatile teaching tool. They can be used for practice with white boards, quizzes, partner or group work, or as an assignment in place of worksheets. Once they are cut out and laminated they will be a resource that can be used for years to come.
This packet includes sixteen task cards. Questions include calculating percent composition of compounds, calculating empirical formula from percentage composition or from mass composition, and calculation of molecular formulas. There are editable task cards included so that you can replace a card or add questions of your own.
Differentiate these cards to meet your needs. You may even want to make two sets of cards for two different classes. That’s what I do. I have a set for my standard class and another set for my honors & advanced honors classes.
Three sets of task cards are included, one with a colorful background, and two black and white choices. Also, you will find a set of edible cards (with color or B&W) that can be used to add cards to the set, or replace a card that you don’t want.
