My daughter, Sophie, on her third birthday: "Mommy let's put three balloons on my chair." After I got one balloon aside from the bunch, I asked her how many more we would need. Sophie: "One, and then one more." Works for me! #iteachmath #tmwyk

A little #math humor. Thanks @vitaminwater! #iteachmath

Filling time at brunch with my 2 1/2 year old. She sorted the sugar packets by color, then counted the amount of each color (including 16 yellow packets!) #iteachmath #tmwyk

When the two pack is not the better buy... #mtbos #iteachmath

My 2 1/2 year old is counting to 20 in her crib, and I don't know if I should be mad that she isn't sleeping or secretly (not so secretly) thrilled. #tmwyk #iteachmath

My 2 1/2 year old will only eat half of what remains of her original bagel each day. She wants to "save the rest for the next day." Too soon for a conversation around the infinite series? #iteachmath #tmwyk

Well... a good day to relate negative numbers to students’ real-world experiences, then? #MTBoS #Iteachmath #silverlining

How am I just discovering Mrs. Maisel? Loving Abe Weissman, the eccentric #math professor, especially his lecture about how the two vectors won't one day decide to get bored of each other and diverge 😂 #mtbos #iteachmath

Come see Eugenia Cheng at @MoMath1 next week! momath.org/civicrm/?page=Civ… #mtbos #iteachmath

Has anyone tried this prompt with students? I'd be really curious to see how some of the students at my school respond. #mtbos #iteachmath #tmwyk Math nyti.ms/2RYcCee

Ah this makes me cringe! Sample solution for a WP, calculating change from a $20. #whataboutnumbersense #iteachmath #mtbos

Hey #mtbos, what student misconceptions do you see most often when teaching finite geometric series? #iteachmath

I think that’s five touchdowns. #iteachmath #mtbos #35to7 #gopats

Okay, some of these got me! But I don't think that SAT question is "the meanest test problem of all time." #mtbos #iteachmath The hardest viral math problems of the year thisisinsider.com/viral-math… via @thisisinsider
