Instead of jumping straight into my height, I figured I would go a different direction and have students estimate my age.
Day 1 #teach180 who would have thought estimating my age would produce great number talk after giving my DOB. #mtbos pic.twitter.com/IR2IVq3qoD— Martin Joyce (@martinsean) August 25, 2017
About 95% of students overestimated my age and I told them it takes a lot to offend me. As you can see from the bottom left of the tweet image above, I honored all responses for my age, after giving them my birth date.
The most common method was students adding 16 to 1984 to get to 2000, and then adding 17 to get to the current year 2017. Then most students who did that added 16 and 17. So, many thought I was 33. I waited, and a couple students reasoned I am not 33 YET, because it's not my birthday yet. On september 4th I'll be 33.
I asked for alternative methods, and students mentioned the subtraction algorithm of 2017 minus 1984.
I then passed out the name tents that offer 5 days of feedback. I've blogged about this before, if you've never heard of it, google Sara Vanderwerf name tent. It's a game changer and most of #MTBoS (math teachers on twitter) are doing it with great results.
Then we read the Chapter 1 intro and had students find the 3 other people in the class that had the matching graph. They glued it on and some started their stories.
With 2 minutes to go, I had students write a comment or question and then collected their name tents at the door.
On Day 2 I had students estimate my height. This time 95% of students underestimated my height. I measured myself at my daughter's doctors appointment and I'm 6'0.5" with shoes on, so I said I'm 6'.
I joked with students that they all think I'm really old and short, when in fact, I'm young, for a teacher, and taller than average people.
Then students finished their graph stories, and then did the 4 coordinate graphing. I'll post photos of these next week. They turned out great. I also have a TA 5th period who is hanging them for me around the room, in preparation for back to school night.
I then found out that Staples was doing their graph paper composition books for a buck each, for the first 30. I got a deal and got all 130 for a buck each.
