Here is a way for beginning chemists to review the skill of multiplying fractions! A segment of the periodic table of elements is presented at the top of the page, from which learners obtain the atomic number to use in six calcualtions. For example, they need to determine which element has an atomic number equal to 5 and 2/5 larger than that of neon. This is ideal for your 5th or 6th graders!
