The top two images show radial designs created with 21st Century Pattern Blocks. The top-left image features six double hexagons arranged around a central hexagon. In the top-right image, six regular hexagons are added to fill in the gaps between the double hexagons, completing the radial pattern. The bottom two images show the outlines corresponding to the designs in the top images.

The main image in the top left shows a radial design created with 21st Century Pattern Blocks. It was built by arranging six identical double hexagons around a central teal hexagon. Each double hexagon is composed of two heptagons joined together using darts. The gaps between the double hexagons are filled in with regular hexagons made from six teal kites. The first image along the bottom shows the double hexagon made from two teal kites, four gray darts, four blue rhombuses, and four yellow hexagons. The rest of the images along the bottom and on the right show the progression of the design.

Hi there #iTeachMath folks.
Need probability help: If 1 snack jar has 12 cookies & 6 pretzels, 2nd jar has 9 cookies & 8 pretzels, if I choose 1 item, what is P(pretzel)??
Is it (1/2)(6/18) + (1/2)(8/17) bc have to choose jar before item?
Or (6+8)/(18+17) bc pretzel/total? seems wrong bc not 1 jar
In my level 2 and then level 5 class, we are going to be warming up with counting squares and rectangles in the chessboard. #mtbos #iteachmath #mathisfun
Puzzle #1
The isosceles trapezoid/trapezium is composed of seven matchsticks.
Modify the position of three matchsticks to get two equilateral triangles.
This puzzle was published on @nctm.org and on @theguardian.com.
Check the solution in the comments.

We had a lot of #mathisfun at the Chapel Hill #mathCircle for 1st-3rd graders looking at circle constructions. One boy whom I picked to be a ‘tree’ coincidentally had green shirt and tan pants, fitting the role as another held a string and walked around him, forming a circle. #mtbos #iteachmath
Rates don’t have to be rushed.
Help students construct the idea of rates using Problem Strings, motion contexts, and double number lines.

“We cannot separate mathematics teaching and learning from the social and political realities students experience.”
This feels especially important right now The position statement offers language & direction for navigating that responsibility with intention
#MathEquity #iTeachMath #EduSky #Blusky
“Students deserve learning spaces where their identities are affirmed and their experiences are valued.”
a reminder that mathematics classrooms are not just about content
they are about people
this statement speaks to that with clarity and care
#MathEquity #iTeachMath #EduSky #Blusky
“Mathematics education must be a space where students develop agency, voice, and critical consciousness.”
This line stays with me, naming what’s possible when we move beyond compliance & toward meaningful engagement w/ mathematics & the world.

“In times of challenge, we must center healing, political clarity, and resistance.”
There is clarity & courage in this position statement reminding us that the work of teaching&learning math is deeply connected to the world students are navigating every day

math shapes how we see issues like this. math ed matters beyond the classroom. It’s not just about getting answers, its about interpreting claims, weighing assumptions, and deciding what counts as fair.
what mathematics do we need to navigate that well?
#MathEquity #iTeachMath #EduSky #Blusky
Mathematics lives inside our biggest social questions. Data, percentages, and models can inform—or divide—depending on how we see them. What might it mean to develop a shared mathematical lens that helps us reason, question, and find common ground?

Is there a valid reason for having students know the coordinates of the special angles on the Unit Circle?
Is it sufficient for them to just know the ratios of the sides?
Use 16 different factors of 630 in a 4 by 4 grid. The numbers in the top row add to 33. The numbers in the second row add to 46. The numbers in the third row add to 85. The numbers in the bottom row add to 544. The numbers in the left column add to 381. The numbers in the second column add to 37. The numbers in the third column add to 11. The numbers in the right column add to 279. The central four cells contain triangle numbers.
Here's a #yohaku to take you into the weekend. Fill in cells with 16 different factors of 630 to get totals shown in each row/column AND shaded cells contain triangle numbers. #mathsky #iTeachMath

Came across this quote from Project Hail Mary
“Math is not thinking. Math is procedure. Memory is not thinking. Memory is storage. Thinking is thinking.”
Really making me think about teaching mathematics. Where does math become thinking? #iteachmath #MTBoS
