Circle 6: Equations and scaling – March 7, 2020

Attendance: Bel (7), Tuh (7), Tari (7), Nia (4), Bab (4), and Dil (4)

We did two activities. I didn’t have much time to prep for these activities and was losing momentum on ideas.

Equations.

I put the following equations with hearts, stars, and drops on the screen. The ones with yellow background were for the preschoolers; the ones with green background were for the 1st grader. 

We did 4 sets in total. 

It was too difficult for the preschoolers. They were also not very focused. After a couple of minutes, Dil said she had to got to the bathroom. This meant that Nia had to go too. After a little bit of coaxing, they did figure out that, if two hearts makes 4, then one heart is 2.

The first graders figures the first three ones out, but not the last one. In the ones they solved, they could figure out what one of the values were and work backward. For the last one, they guessed a few combinations of numbers but unfortunately did not come up with the correct one.

Scaling.

I drew some simple forms on graph paper and asked the kids to make one twice as big.  

The preschoolers did a little bit but it turned out to be too hard for them. I was still very happy that it practiced their skills at copying pictures.

The first graders immediately declared that it was too easy, but then they did spend time doing it. Some of them had small difficulties.

There was about five minutes left, so I finished with …

A riddle.

A little girl lived on the 15th floor of an apartment building. Her mother let her take the elevator alone. But the way she used the elevator was somewhat odd: when she went down, she went all the way down; when she went up she only took the elevator as far as the 7th floor and then took the stairs. 

But when she grew a bit, she started to take the elevator to the 9th floor then took the stairs. 

I asked them why?

The kids said that she wanted to have some exercise. But then I pointed out that she is getting less exercise when she is older.

Dil said that “The problem was ridiculous” and left it at that. Tuh told me that older people can’t walk as much so maybe that’s why the girl went to the 9th floor when she got older. I asked if that was the case, if Tuh couldn’t walk as much as she got older then left it at that.
