Number Sense Activities & Worksheets
Big numbers, fractions, decimals, percents and estimation, all built on things students recognize. They test whether a Halloween candy buy-back is a good deal, size up a massive chunk of ice, and track how fast college costs are rising. Every activity comes with a student worksheet, an answer key and the Common Core standards it covers.
