The mole ratio task cards are an interactive way for students to practice learning mole ratios. The borders of the cards indicate the difficulty level (one line is the easiest, three lines is the most difficult). There are eight cards total. I recommend labeling the backs of the card pages before laminating with some sort of symbol, to make it easier to identify which bag set a card belongs to (for when students leave a card on the floor).
There are two formats of the worksheet, one for interactive notebooks, the other is a standard worksheet format. The interactive notebook pages are useful for students to revisit the problems and study for a test. They write the question on the front of the flap and their work and answer on the inside. Alternatively, these cards could be used with whiteboards, instead of a worksheet.
An answer key is included.
