Find an affine plane of order 4 that includes these two partitions. #math #maths #ProblemSolving #iteachmath #mathsky
Are these two partitions of the dots in a 4x4 grid compatible? (In each grid, the same coloured dots are in the same group) #math #maths #ProblemSolving #iteachmath #mathsky
The largest set we considered yesterday is called the affine plane of order 3. Here’s a representation with each colour indicating a partition in the set. Find a different representation (different set of partitions) of the affine plane of order 3. #math #maths #ProblemSolving
Consider a set of pair-wise compatible partitions of the 9 dots. What’s the largest number of partitions that can be in this set? #math #maths #ProblemSolving #iteachmath #mathsky
Let’s also call two partitions compatible if each group in one partition consists of a dot from each of the 3 groups in the other partition. How many partitions of the 9 dots are compatible with this one? #math #maths #ProblemSolving #iteachmath #mathsky
Happy Monday! This week's problems are inspired by David Butler's post on bsky: buff.ly/wzOUplR Consider all the ways of splitting the following 9 dots into 3 groups of 3. Let’s call these partitions of the dots. How many different partitions of the 9 dots are there?
So I made a video on this week's musings. youtu.be/cEfLzVhZNg8 #math #maths #ProblemSolving #iteachmath #mathsky

Greatest common factor of NON-INTEGERS?
Can a rational number and an irrational number have common factors? Common multiples? #math #maths #ProblemSolving #iteachmath #mathsky
Can two irrational numbers have common factors? Common multiples? #math #maths #ProblemSolving #iteachmath #mathsky
Does the formula GCF(a, b) x LCM(a,b) = axb still work when a and b are fractions? What about the Euclidean Algorithm? #math #maths #ProblemSolving #iteachmath #mathsky
Is there an equivalent of prime numbers when we talk about factors of fractions? Give examples or explain why not. #math #maths #ProblemSolving #iteachmath #mathsky
Happy Monday! This week's problem is inspired by my idle musings. ^^" If we were to extend the definition of factors to non-integers, which of the following would you say is a factor of 2/5: 2? 5? 1/5? 1/10? 2/15? #math #maths #ProblemSolving #iteachmath #mathsky
If we place 4 points on the perimeter of a unit square and add up all pair-wise distances between them, what’s the biggest sum we can get? #math #maths #ProblemSolving #iteachmath #mathsky
If we place n points on the circumference of a unit circle and add up all pair-wise distances between them, what’s the biggest sum we can get? #math #maths #ProblemSolving #iteachmath #mathsky
