Anyone for a block party? If you had to estimate how many pieces are in this pile without counting every one, what strategy would you use? 🟧 🔷
Sometimes the best problem-solving starts with organizing what you notice.

🐸 Spring is tadpole time! These pond critters are giving “not a baby, not yet a frog.” So how old might they be? If you were building a tadpole timeline, what clues would help you make a reasonable estimate? #WeekendWondering

🧸 End-of-year classroom cleanup can spark some critical thinking. Take this stuffed guest, for example. Is it behind the desk, beside the desk, under the desk, or all of the above? Even the quietest classroom friend can create a math moment!

'The over-explaining trap'

🎓 It’s graduation season in the US. As students walk across the stage one by one, their names are called, usually in alphabetical order. But what if you were invited to rethink the tradition? Would you arrange students in a new way? #WeekendWondering

✨ On International Women in Mathematics Day, we’re celebrating the girls who see STEM as a place where they belong and the teachers who support that. When girls have opportunities to be recognized for their thinking, they begin to see new possibilities for themselves!

🎨 This artwork is full of bold shapes going in different directions. If you picked one color at random, do you think it would be a vertical or horizontal shape? What makes you think so? Sometimes taking a closer look helps us see the whole picture! #WeekendWondering

🔢 Numbers have a way of showing up in the most interesting places. "20" might mark an address here, but it could also represent many other things depending on what you notice and how you count. Where else could you find twenty in this scene? #WeekendWondering

Take a look at this ceiling. You might notice a simple grid, but with closer inspection, patterns begin to appear. Larger rectangles are made up of smaller ones, and shapes overlap. How many different rectangles do you think are hiding here? #WeekendWondering #MathIsEverywhere

🐘 It's National Animal Crackers Day! You reach into a box without looking and grab a handful. Some animals show up more than others…or do they?
If you wanted to predict which one appears most, how many would you need to check? #WeekendWondering #MathIsEverywhere
