At #ATMNE25 we are mathematizing with @mrkitmath.bsky.social
The purpose of stories is to build rapport w/Ss and build reason to do the math.
#iTeachMath #MTBoS
Mr Kit Math standing in front of slide "Stories as Mathematizing Out Lives" Mathematizing... -makes math knowledge useful -situates math in context of learner's world -solves problems -is a human activity -is a VERB, an ACTION

Hello #iTeachMath #MathsToday folks... these Yohaku puzzles from Mike are an excellent thinking task for students at many levels. Enjoy!
mikejacobs.bsky.social Mike Jacobs @mikejacobs.bsky.social · 26d
Start your day with this #yohaku. Fill in cells with 9 different factors of 384 to get totals shown in each row/column. #mathsky #iTeachMath
Use 9 different factors of 384 in a 3 by 3 grid. The numbers in the top row add to 34. The numbers in the middle row add to 121. The numbers in the bottom row add to 13. The numbers in the left column add to 32. The numbers in the middle column add to 120. The numbers in the right column add to 16.
