Total Eclipse of the Sun

About two years ago, my husband Aaron told me that in August of 2017 there would be a total eclipse of the sun in North America. He told me he wanted to travel to see the full eclipse. I said something like, “Yeah, that would be cool.” Then, I forgot all about it. Forgot about it that is until last May when he brought the subject up again.

When Aaron told me that it would be something like 100 years from now before there would be another solar eclipse in North America, I couldn't exactly say no. Somehow our schedules worked out, and the more research he began to do the more excited he got (giddy is a better word for it). His excitement has spread, and now our whole house is buzzing, looking forward to the event.  So on August 21^st, we will be near Lincoln, Nebraska to witness a total eclipse of the sun. The whole process will take several hours, while the total eclipse will only last two or three minutes.

Since the eclipse has become a big deal in our house hold, I started to wonder if the teachers would have activities for this event. I am delighted to see NASSA has created a special web page that helps teachers incorporate the eclipse into their lessons. Many NASSA lessons relate to math, science, and geography.

 One activity is a printable book called Our Very Own Star Story which encourages students to explore how far the sun is from earth. Another activity in a Layers of the Sun packet has students graph the increase and decrease of sunspots every 11 years. NASSA also has several math challenge activities that would work great for small group problem solving.

This year's eclipse reminds me that as a teacher, we need to be aware of current events—especially events that rarely happen. As my husband has captured my excitement, I too need to excite my students with events going on around us—as well as link them to math. 

Change in Perspective

I had not expected it. When I enrolled in the college class, “Math for Elementary Teachers I” I expected to learn how to teach elementary math. Yet the math in the text book, the math on the quizzes and the tests felt impossibly hard. Why? I would never be teaching these difficult questions to an elementary class. Emotions were on the rise—confusion, bitterness, low self-esteem, and frustration. Had I enrolled in the wrong class? (I actually checked). Was this a large neon sign blinking,

“YOU ARE NOT CUT OUT TO BE A TEACHER!”?

At about 1:30 in the morning, I found myself paging through that evil math text book. What had I missed? I wanted to know why. Why such difficult math questions? Then, that sweet, glorious light bulb moment. My answer was in the preface. You know, that part of the book that no one reads. There was actually a note meant just for me—“To the future teacher.” My frustration at difficult math problems is similar to the frustrations elementary students feel when they struggle at understanding math. This course will hone in on my creative problem solving skills and teach me to explain why math methods work or don't work for certain problems. In this video, a teacher is using questions to aid her students in developing problem solving skills. (The sound is a bit off in the video but it is still very interesting).

In his video, “Stop Teaching Calculations, Start Learning Maths!” Conrad Wolfram points out that there is a disconnect between the way math is taught and how math is used in the real world. There is a new movement in the way we teach math. It is exciting to be a part of that change! But are we ready as teachers to really help students figure out what works or doesn't work to solve problems, and why? It is our job to shape these little beings into future, expert problem solvers.

The level of difficult for that math course has not changed.  However, I'm learning problem solving skill I never mastered in school. By mastering it, I will create new generations of expert problem solvers. And that change in perspective has made all the difference!
