Thought about mapping activity

I was reading a few teachers talking about teaching their students to use maps and analyse the changes as well as using GPS and geocashing to use latitude and longitude. Correct me if I'm wrong, but you guys are science teachers?

Based on that assumption, I was thinking it would be neat to incorporate a corresponding math project involving graphing. Maybe the students first learn about it with the science teachers. They do the project based lesson with maps and GPS. Then they could come to my math class and create their own map including cordinates. They could use slope and find distances between locations on their map. They could even hide their own treasures around the school campus and then trade their maps with other students to find each others' "treasures." They could use the concept of slope to tell students how to find the treasure. Maybe they have to start at a certain latitude or longitude and then go a certain direction with a certain slope, and they would actually have to walk the number of steps up and over.

If I'm confused, and you guys are actually math teachers, then I want to steal your lesson : ) If you are science teachers, I still want to steal your lesson and see if some of my science teachers will use it so we can create a math/science combined project.

God and Classroom Management

Ezekiel 20:11-13 "I gave them my decrees and made known to them my laws," (God gave clear and consistent expectations. I would bet he made sure they were available in multiple formats so people could both read and hear them.) "for the man who obeys them will live by them." (I have way more wisdom and knowledge, not to mentioned a fully developed frontal lobe. I know the results of those bad choices already, so seriously, listen to me for your own good...) "Also I gave them my Sabbaths as a sign between us, so they would know that I the Lord made them holy." (Here I imagine God feels like I do when I spend hours planning a hands-on lesson that would make me curious and excited as a student. I bet he looked forward to the Sabbath because he imagined how excited he would be as a human to have this day to rest and appreciate what a great and loving God they have. He wants us to know he loves us and wants what's best for us, just like I want my ...

Second Chances

I've been thinking about second chances constantly lately. As an adult, think about all the times you've been given a second chance. I am not a perfect wife, but my husband gives me second chances all the time.  I tried to make cookies once with baking soda that was 2 years expired. They didn't turn out so great, but I have had other chances to bake things and I learned a value lesson about baking soda : ) I tried out for my church praise team and didn't make it. It was embarrassing and for a while I didn't feel like singing or playing the piano, but I can try out again and if I don't get so nervous next time, maybe I'll make it. I'm not banned forever because of one audition. I took the ACT twice when I was in high school, and my highest score was the only one colleges cared about.  My first year of teaching, I struggled quite a bit with classroom management. I needed more time and unfortunately first-hand experience to just begin lea...

School vs. Real Life

I read a post on facebook today about things in the real world that students don't learn in school. It got me thinking about how we spiral everything in Geometry and Algebra 2. Here's how it works... We teach a brand new unit for about 2 weeks. During that time, we review something from a particular previous unit each day so that by the end of those two weeks, they have learned all the new material a little bit each day and reviewed all the "spiral" material a little bit each day. Then we give two tests, one over the new material and one over the "spiral" material. By doing this, they will experience all material once as new and a second time as spiral. This will allow them to take two tests over every unit. Their first test score affects their grade, but if they score higher on the second test, they get to keep just the higher score. If they score lower on the second test, we average the two test scores. Most students score higher on the second test becau...
