@cravenscience1 @adamboxer1 @MrARobbins @Mr_Raichura @MissBird90 Printed hard copy with space to complete. 4 fluency questions on the front, fifth conceptual question on the back. Students collect on the way into the room. Minimal faff time. Vary answer collection based on q's, vibe & class. I have tried most approaches. Hard copy for the win!

@adamboxer1 This reminds me of this idea. I don't love talking about schools as markets but I feel there is certainly aspects of this across a school environment. Creating 'social proof' is so key, for teachers to come on board. Typically that social proof is 'bang for buck' in terms of time

@howie_hua Double 90, take 3

@howie_hua @MikeFlynn55 I'm seeing it as a mean problem and picturing stacks of cubes. Break off 2 from 15 and add it to the 11, break off 1 from 14 and add it to 12. Then you have 5 stacks of 13. 13*5 =65

@TheAlexFenton @mtngry @sage_stage It's called the deferred salary scheme or more colloquially called 4 for 5..

@StudyMaths I've been using bar models for a while but still 🤯

@mtngry @sage_stage I was just about to jump on here to say the same thing....

@adamboxer1 I'm sure you have answered this before but rather than scroll through the many many posts on this. I find One Note tools visible on the screen distracting and literally just want the question and a blank screen for me to write on. Is this possible in OneNote?

This is a very cool thread...

What's your favourite thing about Pascal's Triangle?

[Sally Cassilles @SCassilles]

@ddmeyer 13th. Get students into routines through learning maths, hopefully with a good hook.

@howie_hua 3 yellows and 4 'other'

@misterwootube @KirstDy @ImpactWales Am I reading this right? Your hand writing is so good that it could be an actual font?! That is impressive...

Thanks to the amazingness that is the Riverina Network of Mathematics Teachers!

[Sarah Warry @warry_sarah]

What a day! Representatives from 15 schools all coming together to network and learn more about teaching mathematics! I love my job! @_thomas_pollard @SCassilles @MathsGrowthTeam

Looking for a video by @howie_hua demonstrating how to do the problem of a 10 digit number where the first digit is divisible by 1, first 2 digits concatenated divisible by 2 etc. using digits 0-9 only once. Can anyone help me with finding the video please? TIA

@ryannoonan5 @mcgrathnicol Congratulations! Still sad we lost you but no doubt you are on to bigger and better things!

@MarianaPT_OCT @pwharris You must either live in my brain or we both listen to too much (is there such a thing?) #MathIsFigureOutAble 🤣

@aliceleung I was never a morning person. New outdoor gym opened in town 6yrs ago & I started doing a 6.15 class. Progressively got earlier over 6 yrs & now the alarm is set for 4.39am. I love it. It's actually amazing just how many people are up at crazy o'clock doing the same thing!
