This case stumped me when I was first exploring this problem. I sat there staring at my scrap paper with my face all scrunched up going "Isn't that an odd number? Aren't these same coloured squares? What am I missing?" Those are the moments that make this fun. #MathSky #StorySaturday

f. Find a path from A to B that goes through each cell exactly once moving only vertically or horizontally at each step.

#hottake: People underestimate the time problem solving takes. It's normal to not know how to solve it at first glance. It's normal to not know after days. The point is to keep trying things when you don't know. That persistence is more important to teach our kids than the solutions. #MathSky

d. Find a path from A to B that goes through each cell exactly once moving only vertically or horizontally at each step.

#hottake: It's not the math teachers' job to come up with good math problems outside of the textbooks, just as it's not the English teachers' job to write all the stories and not the music teachers' job to compose all the songs. That's a separate profession we need for math. #MathSky

Sorry I was gone for 4 months when I said I was only taking a month-long break. 😅 I now have my ducks in a row with a (hopefully) more sustainable posting schedule. Stay tuned starting this week. 😉
#MathSky

I just realized I do the pokemon thing but for math problems. 🤔 I catch them and "train" them until they evolve into a book or a video. 😅

I made this week's problem into a video too.

Sorry to take another break from the posting schedule so soon, but we have a family trip coming up. See you again in a month or so. ☺️

f). How many different arrangements of the name cards for n people (where n is odd) are there that have this property?

e). Prove or disprove that no arrangement of name cards work for even numbers of people.

d). Prove that the reverse order arrangement of name cards always work for odd numbers of people.

c). How many different arrangements of the name cards for 4 people are there that have this property? 6 people? 7 people?

I made these books for my own kids. If you're a math problem enthusiast and have a child in your life with whom you want to share that love of math, feel free to check them out.

b). How many different arrangements of the name cards for 5 people are there that have this property?
#math #maths #ProblemSolving #iteachmath #mathsky

Happy Monday! This problem is inspired by the 1975 CMO Q6ii
Here are 5 people at a meeting. Notice if we place their name cards in reverse order, no matter how we turn the table, only one person will have the right name card at any time.
a). Find a different arrangement for 5 people like this.

So I made a video on this week's problem too.
