- Topics: Addition, Graphs, Time: Book: Get Up and Go! by S. Murphy.
- Topics: Logic, Venn Diagrams: First, we did our standard Venn diagrams activity using fairy tale characters. The two problems we did were “Animals” and “Magic”; and “Scary Things” and “Girls”. Then I shuffled up the cards and flipped over sets of 4 (later 6) cards, and the kids had to come up with as many different ways to group the cards into two groups, with explanations.
- Topics: Simulation, Charts: I introduced “Star Wars battles”. The idea is that you have two characters, each with a certain amount of Attack and Health. Each simultaneously deals damage to the other, and when you get to zero health you are knocked out. The battles end in a tie if both are simultaneously knocked out. They also can have armor, which reduces the damage received by one each time. I designed 6 characters (we happened to have figures for all of them): Kylo Ren (4 attack, 4 health), Rey (2 attack, 8 health), BB-8 (1 attack, 12 health), Flame Trooper (6 attack, 1 health), Finn (6 attack, 6 health), and Phasma (1 attack, 9 health, 1 armor). We used glass beads to keep track of health, and the kids took turns setting up and running the battles. We started with the first 4 characters and played all pairs; I kept track of the results on a chart (see picture). Then we added Finn, did all the pairs with him; and then Phasma. Then we figured out the win-tie-loss records for each character and compared them. Finally, I asked them whether they could make a character that tied with Finn.
How Did It Go?
We only had two kids this week; as usual things were easier with such a small group.
Get Up And Go!
A straight-forward book about getting ready in the morning, adding up the time for each individual activity in order to get the total time to get ready. I gave each of the kids a worksheet to take home and fill out for their own routine.
It’s been a while since we did Venn diagrams, one of the kids remembered them pretty well but the other was rusty. The fairy tale Venn diagrams is always fun because the kids have to decide what’s an animal, what’s magical, what’s scary, etc. This time, the gingerbread man wasn’t magical, for Pinocchio: Child: “Is this magical?” Me: “It’s a living puppet.” Child: “Ok, no. Wait, yes?”, ogres and trolls are animals.
Grouping the cards is also fun. I stumped them once by grouping a cat, bear, and wolf together vs. a dragon, goose, and frog. They often went for very small bits of color when grouping cards. My favorite was “bent legs”, when “legs” would have accomplished the same split.
Star Wars Battles
Our son has been doing something similar outside of circle on his own, so naturally he loved it. The other kid also liked it quite a bit. It took a bit of time for the other kid to catch on, but by the end both kids could run the battles smoothly using the glass beads. With the stats I picked, it’s pretty interesting because it’s quite non-transitive: Finn has the best record (4 Wins, 1 Tie) while the Flame Trooper has the worst (2 Ties, 3 Losses), yet Finn and the Flame Trooper tie. For the final question about tying Finn, our son was able to figure out that he would tie with a character with 1 attack and 36 health, because 6 * 6 = 36 damage from Finn. Pretty nice!
Reading the chart was somewhat tricky, so only one of the kids followed the second part about calculating the records for each character and comparing them.
