This worksheet is formatted in the way they may see the question on a state exam. The answer choices are all equations they must count atoms to in order to determine with both sides of the equation are equal. There is a coloring key for a hello kitty picture I drew attached to their answers. If students circle the correct answer, their picture should be colored correctly. For example, if the answer to #1 is "A" then they have to color all parts of the picture labeled "A" red. It's tiered for level and advanced students!
