This product contains problems that pertain to the common core math standards 5.NBT.1 and 5.NBT.3 (decimal place value and reading,writing,comparing, and rounding decimals). It can be used to challenge the higher-level students, as a center activity, for early finishers, or to review the concept. Students locate the first treasure chest that says "Instructions", which they have to scan with a QR reader to read. Make sure that iPads or other mobile devices have the free QR reader app downloaded. The students must then solve various types and levels of decimal problems to complete a scavenger hunt. They will scan the treasure chest hat says "Start" to find their first problem and then locate the treasure chest with the answer that holds the QR with the next question, which they record on their student answer sheets. The kids LOVE these and it's a great way to integrate technology into the classroom.
