Circle 3: Which one doesn't belong? January 4, 2020

Attendance: Bel (7), Tuh (7), Tari (6), Nia (4), Bab (4), and Dil (4)

I started this math club with the activity "Which one does not belong?". I put images with 4 things on the monitor and asked the kids "which one doesn't belong?". There is not one answer to the question. The important part was that they justified why the one selected was different from the other. Then we tried to find a reason why each of them was different from the three others. I got most of the pictures from https://wodb.ca/shapes.html but a search for "which one doesn't belong" gives a ton of images too. 
  • The kids took to it. They were engaged and could describe their reasoning well. Even the younger kids were excited about this and Bab, who did not talk much before answered a lot of them.
  • Sometimes, they just said “this one does not belong because it is the only one with my favorite color”.
  • There were a lot more discussions about the houses and they found many more details.
For the next activity, I prepared a discussion on Definitions and the need for them. Previously, we talked about whether we wear umbrellas ("Noooooo"). I tried to prompt it by telling them how sometimes, mom and dad ask them to be quiet and even when they are whispering, it is not quiet enough and it's confusing. It was because we attach different meaning to words. 

It didn’t seem to get through. With the math club, I try really hard to let the kids think and explore. But they do need definitions. I can’t expect them to conclude that squares are rectangles if they don’t really know what is a rectangle. I am not sure how much they understood. There was some disagreement over whether one “wears a purse”.

Sudoku (part 2): I gave each of the younger kids a white board with 4 out of 9 squares of a 3x3 grid filled. I told them that there should be one circle, one square, and one triangle in each row and column and asked them to fill the rest. The older kids had a 4x4 grids with squares, circles, triangles, and stars (sudoku 4x4 are very easy to find online). 

The group with Nia, Bab, and Dil figured out the 3×3 puzzle. I then gave them a 4×4 but they did not like it. The problem was that they could not draw stars (something I did not anticipate) and were much happier when I replaced the stars with smiley faces. They can do it one step at a time with help but not string it all together if there are too many many steps.

Tari, Bel, and Tuh quickly finished their puzzles. I had prepared more and they had to copy them onto their white board first. But they decided to create their own, so the first kid declared she would do a 5×5, then the next kid a 6×6 and it escalated to 8×8 with a lot of craziness (drawing on sleeves with markers) and giggling while I was helping the other group. Unfortunately, this is when the parents showed up to pick up their kids so it looked… chaotic. I think I will print out worksheets next time and give them harder puzzles.
