7th - 9th Grade
Need some extra material to teach the concept of irrational numbers? This resource is for 8th grade students who are studying about irrational numbers, or it can be used with grades 7-9 as an extra material for math oriented / talented students.
Crossword asks about concepts that are related to rational and irrational numbers and number sets in general. That can be easily used as part of courses 8.NS.A.1 or 8.NS.A.2 with all students.
There is also something about history of irrational numbers and a proof that square root of 2 is irrational. The proof goes beyond standard curriculum for 8th graders, but can be introduced as extra information.
