Today we took a quiz over our measurement unit in class. I think I did okay. However, there were a few questions I wasn't too sure about, and I began to second guess myself. I especially doubted myself on multiplying, dividing, adding, and subtracting significant numbers. In addition, I had trouble with a question asking about a pure substance. So, I went to find more practice questions online that combine multiplying/dividing and adding/subtracting with significant numbers, and a page explaining more about pure substances, elements, and compounds. I plan on looking back at these links as I study for our upcoming exam.

Thanks you for sharing those links Lily! They are very helpful for practicing addition, subtraction, multiplication, and division of significant numbers and understanding pure substances.
