Resharing this video just in case someone wants to know how to divide with this "new" way

[Howie Hua @howie_hua]

What's with this "new" way of dividing?

[Dorothy Matheson Dalton @DoMathDifferent]

Enlightened. Every. Single. Time. @pwharris Renaming 2/5 as 2 x 1/5 to solve problems more efficiently 🙌🏼 #ReachMoreStudents

The ending 🙌🏼

[Howie Hua @howie_hua]

Do you think about rectangles when multiplying? If not, I highly recommend it, and here's why!

[Howie Hua @howie_hua]

Why is seeing math as a creative subject important when algorithms work every time?

@alisonmellomath “The other F word” 🤣🎯🙌🏼

[Dorothy Matheson Dalton @DoMathDifferent]

@alisonmellomath @BuildMathMinds You’re welcome, and thank you for sharing!!

[Dorothy Matheson Dalton @DoMathDifferent]

This session was awesome! I love how @alisonmellomath explained how tricks place a lot more “cognitive load”on our kids.🙌🏼@BuildMathMinds

[Alison J. Mello Ed.D. @alisonmellomath]

Day 1 of the @BuildMathMinds Summit is in the books! So many great sessions, great people, and great learning!
Let's do it all again tomorrow! Join me at 11:00 Eastern as we discuss ways to upgrade our instruction by replacing tricks with thinking. Hope to see you there! 😀👇

[Dorothy Matheson Dalton @DoMathDifferent]

@alisonmellomath I totally agree! I felt so validated watching your session!🙌🏼 I also teach my 5th graders not to move the decimal and not to add that zero & am still learning to stop the insanity😉. I appreciate your session!!💗

[Dorothy Matheson Dalton @DoMathDifferent]

Today, my 5th graders explored finding the GCF using the Euclidean algorithm (as shown by the fabulous @howie_hua ) with both tactile & pen/paper versions. So empowering!🤩🎉@hickoryschools #numbersense #greatestcommonfactor #MTBoS

[Dorothy Matheson Dalton @DoMathDifferent]

My kids had so much fun exploring this today!

[Howie Hua @howie_hua]

I wish I was taught this way of finding the greatest common factor when I was in school

[Dorothy Matheson Dalton @DoMathDifferent]

@howie_hua They loved it!! My girls are finding the GCF of 30 & 40 (I think they added an extra step at the very end, b/c they already had the GCF of 10), and he is finding the GCF of 26 & 12. Thank you so much! They will explore more tomorrow!👏🏼🎉

[Dorothy Matheson Dalton @DoMathDifferent]

@howie_hua Will do!!
