California Math Standard 6.NS.3
Students can practice all four decimal operations while also having the added rigor of know how to write expressions (using sum, difference, product, and quotient). Students participate in a scavenger hunt as they search for answers. I have had my students do this activity in partners or small groups of three, though I believe individuals could do this, too. Students can go through at their own pace and check with you as you monitor their progress. It's a fun way to do a review of decimal operations!
