This LGBTQ+ History Month, we recognize the importance of ensuring LGBTQ+ stories and voices are included in the classroom. Every student deserves to see themselves reflected in what they learn.

Calculus was one of my banned books growing up! 😂 Many students feel the same way and don’t see calculus as accessible! Calculus should not be a sorting mechanism, it’s an opportunity of discovery! #calculus #bannedbooks

Students ask "Who does math?" more than we think. Lathisms features a Latinx or Hispanic mathematician every day of Hispanic Heritage Month. My students pick one and share what surprised them. Who do you introduce to your class? #MathSky #HispanicHeritageMonth

Nearly 1 in 4 people in the U.S. speak a language other than English at home. 🌎 My new data talk turns real Census data into a MS math conversation that builds to one question: Who is missing? 👥 Tag a math teacher who would use this. Comment "HELLO" to get the resource 👇 #iteachmath #MathSky

Area models are my go-to for teaching multiplication and division. They help students see the inverse relationship between each operation.

Try this shady #yohaku. Fill in cells with 9 different integers to get products shown in each row/column AND sum of 4 shaded cells is -2. #mathsky #iTeachMath

Use 9 different integers in a 3 by 3 grid. The numbers in the top row multiply to -42. The numbers in the middle row multiply to 55. The numbers in the bottom row multiply to 54. The numbers in the left column multiply to -66. The numbers in the middle column multiply to 63. The numbers in the right column multiply to 30. The sum of the integers in the 2 by 2 square at the top left of the grid is -2.

One way to make a task harder to hand off to AI: students collect their own data first. No chatbot knows how long the line is at OUR cafeteria. What's your favorite AI-resistant task? (Article link in the comments 👇) #EduSky #MiddleSchool

#ALevelMaths Looking at iterative solutions to equations today, so I wrote this root finder in @desmos.com, utilising the Newton-Raphson method. r(a, n) uses n iterations starting at x=a to identify a root. #MathsToday www.desmos.com/calculator/4...
