Yes. Although it was years ago as I have not taught straight geometry for many years. I gave been teaching remedial math for seniors who did not pass our state graduation test and one of our proplems we give (based on a previous state problem) has to do with areas of a quilt and quilt block. So I do add it in. Used to think you could do a whole basic math couse around building a model railroad. Am now thinking whether that could also be done around quilting. Haven't been quilting long enough to have it all clear yet but I'm thinking about it.
