Peter RowlettHere’s a maze he made. We found there were two ways to get from the start (1) to end (8) in six steps. <a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a>

Tommaths (he/him)(2/2)... If you do Talk about <a class="hashtag" href="https://bsky.app/search?q=%23Maths" rel="nofollow noopener noreferrer" target="_blank">#Maths</a> With Your Kids, maybe post about it so that others can gain from your insights. If you include <a class="hashtag" href="https://bsky.app/search?q=%23tmwyk" rel="nofollow noopener noreferrer" target="_blank">#tmwyk</a> this'll make it easier to find (& the attached feed will grab it, so do pin and share with others! There's not much there at the mo so... put that right?)

Tommaths (he/him)For anyone passing by, I made a <a class="hashtag" href="https://bsky.app/search?q=%23tmwyk" rel="nofollow noopener noreferrer" target="_blank">#tmwyk</a> feed: <a href="https://bsky.app/profile/did:plc:t5yakedpwanytlgnlrsxn6jw/feed/aaajrpbibyo62" rel="nofollow noopener noreferrer" target="_blank">bsky.app/profile/did:...</a> RE: <a href="https://bsky.app/profile/did:plc:t5yakedpwanytlgnlrsxn6jw/feed/aaajrpbibyo62" rel="nofollow noopener noreferrer" target="_blank">https://bsky.app/profile/did:plc:t5yakedpwanytlgnlrsxn6jw/feed/aaajrpbibyo62</a>

Tommaths (he/him)Slightly disappointed that not many people are posting about talking maths with their kids, so I made a feed in the hope that people will fill it up by talking maths with their kids then posting about it including the <a class="hashtag" href="https://bsky.app/search?q=%23tmwyk" rel="nofollow noopener noreferrer" target="_blank">#tmwyk</a> tag. So have *you* Talked Maths With Your Kids recently? <a class="hashtag" href="https://bsky.app/search?q=%23mathstoday" rel="nofollow noopener noreferrer" target="_blank">#mathstoday</a> RE: <a href="https://bsky.app/profile/did:plc:t5yakedpwanytlgnlrsxn6jw/feed/aaajrpbibyo62" rel="nofollow noopener noreferrer" target="_blank">https://bsky.app/profile/did:plc:t5yakedpwanytlgnlrsxn6jw/feed/aaajrpbibyo62</a>

Peter RowlettHe also wrote out the times table to 9x9 and added the entries to get 2025. Here he was very taken that we could get the row sum for 2 by doubling the row sum for 1, then add these together to get the sum for 3, and so on.<a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a>

Peter RowlettI was quite taken with this one: 2025 is the product of the proper divisors of its square root, 45. My son showed me how at school they’d make a factor bug to find the factors 1, 3, 5, 9, 15 and 45, then we worked out 1×3=3, 3×5=15, 15×15 we did as 10×15 plus half as much again to get 225. Finally he did 225×9 by doing 225×10 and subtracting 225.<a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a>

Christian Lawson-PerfectMy daughter got a board game from a relative, which wasn't much cop really, but we've had some great maths chat with the leftover packaging.We had these 2×3 grids. I showed her how you can make a pattern with eight holes by putting two grids on top of each other.I asked which numbers we can make. We did multiples of 2, then I asked if we could make an odd number. Are there any numbers we can't make?<a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a>

Colin the MathmoI've been thinking about this for ages, but never had the time to craft the words around it.People keep saying that "Maths should be fun" ... and I push back with "It should be engaging ... 'fun' is a different thing.So <a href="https://mathstodon.xyz/@rakhichawla" class="u-url mention">@rakhichawla</a> has posted pretty much exactly this, but better than I ever could.I'm copying it here with permission.Please read this, then as it says at the end ... let's have a deeper conversation about this ...1/n(PS: I'd love this to get boosted to get outside my bubble ... you're all amazing, but there will be other opinions, and other thoughts that could be helpful or valuable)Hashtags: <a href="https://mathstodon.xyz/tags/MathEd" class="mention hashtag" rel="tag">#MathEd</a> <a href="https://mathstodon.xyz/tags/MathsEd" class="mention hashtag" rel="tag">#MathsEd</a> <a href="https://mathstodon.xyz/tags/MathEdChat" class="mention hashtag" rel="tag">#MathEdChat</a> <a href="https://mathstodon.xyz/tags/MathsEdChat" class="mention hashtag" rel="tag">#MathsEdChat</a> <a href="https://mathstodon.xyz/tags/MathChat" class="mention hashtag" rel="tag">#MathChat</a> <a href="https://mathstodon.xyz/tags/MathsChat" class="mention hashtag" rel="tag">#MathsChat</a> <a href="https://mathstodon.xyz/tags/MTBoS" class="mention hashtag" rel="tag">#MTBoS</a> <a href="https://mathstodon.xyz/tags/TMWYK" class="mention hashtag" rel="tag">#TMWYK</a>

Peter Rowlett<a href="https://mathstodon.xyz/@byorgey" class="u-url mention">@byorgey</a> excellent! There used to be a hashtag in the other place <a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a> for ‘talking math with your kids’, which hasn’t really taken off here but is a nice idea.

Brent YorgeyI found 7yo drawing on a sheet of paper. He had drawn 8 dots in a circle and was drawing lines between all possible pairs of dots. I told him it was called \(K_8\) (and showed him how to write the 8 as a subscript). He thought that was cool and labelled his drawing. I then asked him to draw \(K_3, K_2, K_1\), and \(K_0\). He did not even hesitate at \(K_0\) but gleefully wrote \(K_0\) labelling a blank part of the paper.He then wanted to draw \(K_{10}\) but I told him it would take too long (we had to leave shortly). I tried to explain something about how the number of lines grew quadratically, though not in those words of course. "Oh yeah," he said, "like how \(K_8\) has eight times seven lines." He double counted them, of course, but I was impressed he thought of a way to count them at all.Looks like we have another budding mathematician on our hands! <a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a>

Colin the MathmoSome time ago ... (A month!) ... there was a thread on Twitter that I think should be shared here. I've been trying to extract and post it semi-automatically, but Twitter just makes it damn near impossible.So I'm copying it "by hand"Here's a chart of the full conversation:<a href="https://www.solipsys.co.uk/Chartter/1856750472826085652.svg" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://www.solipsys.co.uk/Chartter/1856750472826085652.svg</a>Here's the head of the conversation:<a href="https://x.com/TweetingCynical/status/1856750459110986045" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://x.com/TweetingCynical/status/1856750459110986045</a> <a href="https://mathstodon.xyz/tags/MTBoS" class="mention hashtag" rel="tag">#MTBoS</a> <a href="https://mathstodon.xyz/tags/TMWYK" class="mention hashtag" rel="tag">#TMWYK</a> <a href="https://mathstodon.xyz/tags/MathChat" class="mention hashtag" rel="tag">#MathChat</a> <a href="https://mathstodon.xyz/tags/MathsChat" class="mention hashtag" rel="tag">#MathsChat</a> <a href="https://mathstodon.xyz/tags/MathEd" class="mention hashtag" rel="tag">#MathEd</a> <a href="https://mathstodon.xyz/tags/MathEdChat" class="mention hashtag" rel="tag">#MathEdChat</a> <a href="https://mathstodon.xyz/tags/MathsEd" class="mention hashtag" rel="tag">#MathsEd</a> <a href="https://mathstodon.xyz/tags/MathsEdChat" class="mention hashtag" rel="tag">#MathsEdChat</a> I will occasionally update the chart of *this* conversation, and it will be here:<a href="https://www.solipsys.co.uk/Chartodon/TeachingTellingTheTime.svg" target="_blank" rel="nofollow noopener noreferrer" translate="no">https://www.solipsys.co.uk/Chartodon/TeachingTellingTheTime.svg</a> Here is the content ...

Colin Beveridge<a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a> "I noticed that if you take the difference between a cube and the one before it, take away one and divide by 6, you get the triangle numbers." Blooming 'eck, kid.

Tommaths (he/him)(9/13) F. An excellent way to develop your own mathematical positivity is to introduce more <a href="https://bsky.app/search?q=%23maths" rel="nofollow noopener noreferrer" target="_blank">#maths</a> positive people into your life. You're on BlueSky: follow some! (Hi!) Interact with them. Ask them things. Share the mathematical discussions that you have with with your kids (include <a href="https://bsky.app/search?q=%23tmwyk" rel="nofollow noopener noreferrer" target="_blank">#tmwyk</a> )

Colin Beveridge10yo: "the question was 'does every multiple of six have a prime either side of it?', and I said no, because of 0." He's very put out that the teacher disallowed it because it wasn't on the hundred square. <a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a>

Peter RowlettMy son answered a maths worksheet question earlier. It said ‘Sam’ used this method to find a prime factorisation: 18=2x9=2x3x3 Then it asked you to use Sam’s method to answer some questions. The first question was 36. He did this: 36=2x18=2x9x9=…Somehow he saw 9 as made of 3s and 18 as made of 9s. An interesting mistake! <a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a>

Colin BeveridgeAnd now the 10yo has observed that the sum of the squares in the \( n \)th row of Pascal's triangle is the middle term of the \( 2n \)th row. He had a pretty good explanation for why, too 🙂 <a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a>

Colin Beveridge(And I should tag it <a href="https://mathstodon.xyz/tags/tmwyk" class="mention hashtag" rel="tag">#tmwyk</a>, because of the origin story.)
