SOL 3.12 Measurement

Content:

- 24 hours in a day
- 7 days in a week
- 365 days in a year
- 12 months in a year
- Misconceptions- not all months have 31 days so not all months have 4 weeks and not all months start on a Monday

Pedagogy:

- Hands on approach and visual manipulative along with class lecture and discussion

Technology:

- Large calendar
- Small blank paper calendars
- Paper circles

Lesson:

I would start with asking my students what they knew about the calendar and then would put on a large calendar that everyone would be able to see and have everyone observe the calendar and make observations as a class. This is where I would start talking about the misconception that not all months actually start on a Monday and not all months have 4 weeks. I would then ask if anyone could think of why not all months start on a Monday, then I would have them writing at the top of their circle Monday then the rest of the days in order around the circle (like a clock) then would explain how weeks work like a cycle just like time and always go in the same order. So, each month has to pick up where the other left off so if the 31^{st}was on a Thursday the 1^{st}of the next month would then be on Friday Then we would talk about how not all the months have 31 days and I would explain how this is because a very long time ago they realized if the calendar followed the moon cycle there would be 29.5 days in each month of the calendar which would be years of 354 days but the orbital period of the Earth is 365 days. This made the calendar out of sync with seasons and this was bad. Then I would have them all think of their own calendars and they would make them on the blank calendars. Then I would have them share what they came up with for their calendars. After I would explain how back then they too tried to change the calendar and add a 13^{th}month but that was just too confusing so Julius Caesar reformed the calendar by ordering the year to be in 365 days so it would be set up to follow the seasons; this forced some days to be added to some of months to bring the total number of days from 354 to 365. Then I would teach them knuckle trick where the months that land on your knuckle have 31 days.

Technology, Content, and Pedagogy all work together to make an effective lesson because it helps the teacher stay organized and map out their lesson and how they are going to integrate technology in their lesson. By integrating technology into the lesson it enhances the students learning. They will be a lot more engaged in the lesson and have better chances of actually grasping and remembering the information.
