Very exciting to have our new Lego Mindstorms Robot Inventor kits arrive this week. The new Mindstorms program is awesome and our grade 6-8 Robotics Club coached by @MrRCartwright are really enjoying exploration. @DDSBSchools @DDSB_STEM

Made another #MatchMyCL for this month. Exploring the relationship between diameter, circumference and area of circles with some visual feedback. teacher.desmos.com/activitybuilde…

Sketch some parallel lines @desmos #MatchMyCl teacher.desmos.com/activitybuilde…

@ddmeyer 24 m: added all sides and 75m: (6+9)x5

I love what students did on this pre-test for our area & volume unit. We asked for area. ✅ 31% said 30 m^2 ❌ 12% said __ ❌ 11% said __ Those last two answers were both #WrongAndBrilliant. What were they? What were students thinking? 🧦 Des-socks to a couple random replies.

@dwekselgreene @mrchowmath @Desmos This is awesome!

Thanks to @mrchowmath's help, this new @desmos version of 24 Game has a student Challenge Creator, so they can make up their own and solve each others' cards. #MTBoS teacher.desmos.com/activitybuilde…

Please share this video with anyone who says that they're not a "math person." #mtbos #iteachmath

@MrCorleyMath I made this @desmos screen to pick random groups. teacher.desmos.com/activitybuilde… You can adjust the size of your class in the graph and change the labels to student names. I have a copy of it for each class I teach and use it all the time.

Hey #iteachmath ! Who has a good random group generator website they like? Hoping to be able to save classes and adjust group size. TIA!

@mrchowmath Great suggestion. The points now move towards your input instead. Loving how much more interactive the activity now feels. teacher.desmos.com/activitybuilde…

@MrRCartwright I like how it shows me the graph of my response. I'd LOVE to see if my wrong answer ever gives the correct amount.

Here's my November #MatchMyCL challenge: teacher.desmos.com/activitybuilde…. Graphing and rearranged arrays to provide students with some visual feedback if their expression matches the pattern.

@KenClarkson3 @Desmos Nice! Yes, it is a random number 1-12 each time.

Here's my @desmos October #MatchMyCL. teacher.desmos.com/activitybuilde… Some multiples and factors fun!

Student led morning announcements on Google Meet is quickly becoming my favourite part of the day. Thanks, today’s group, for sharing a video recognizing #AsianHeritageMonth @ValleyViewPS

Incredible performances at the 5th annual @ValleyViewPS Slam Poetry Contest. Such an amazing way for students to share their voice

Can you solve this @openmiddle @Desmos clock challenge? #iteachmath #mtbos teacher.desmos.com/activitybuilde…

@mrchowmath Had some cursor fun with this #matchMyCL. Can you swat the fly? teacher.desmos.com/activitybuilde…

Ready for the second #MatchMyCL Challenge of 2021? This month, let's just have some fun. Use currentX and currentY to make your own sketch cursor! Here are a few quick examples: teacher.desmos.com/activitybuilde…

@Errs5 Fun with 9s! 19/2, 29/3, 39/4, 49/5... Very interesting

🧐What do you notice here? #iteachmath #MTBos #fractions

@Errs5 Nice. Same as the numerator in the mixed.

@Errs5 The ones digit of the numerator in the improper fraction is the same as the whole number digit in the mixed fraction.

@ValleyViewPS students using @desmos concept circles and manipulatives. Great conversations and #mathematical #reasoning today. teacher.desmos.com/activitybuilde…
