@cjshore @blatherwick_sam Lesson for year 11 today. All lessons will follow this structure and students can access before/after class.

Maths teacher friends. If you can, please can you take a picture of your lesson plans / lesson planning (so long as no pupils mentioned etc). I’d love to see what your looks like ‘in reality’ to show PGCE students.

@MathsCirclesOz 3/16 + 1/4 = 3/16 + 4/16 = 7/16 just under 1/2

It's Maths Talk Monday! Choose any 2 fractions in this square. What fractions can you make? Share your approach, or one you find interesting! For fresh, new maths teaching ideas to your inbox, sign up at ➡️ loom.ly/o0Dfxqg

@nomad_penguin Starter question to work through (sometimes individually, sometimes collaboratively), a kahoot/blooket etc. For my older students in revision time I'm currently doing timed practice questions.

Hello folks. I’m looking for blog posts / “tweets” / thoughts on how you start your (secondary) maths lessons. Thank you! #MTBoS #iTeachMath

Thanks to @UniMelb for your workshop today with some Year 7 and 8 students. An engaging task looking at symmetry and patterns.

@DavidKButlerUoA - loved using your stick figure cards in class today. Students worked in pairs to choose variables and 20 'people' to base their investigation on. Engagement high, allowed for targeted clarification + feedback, + additional real life considerations.

@jillbrown_AUS Thank you for the session Jill. Extremely practical and left feeling inspired 🙂

Great sessions on Wednesday at the Mathematics Discipline Day, great to see so many teachers of mathematics F-12 ... so keen to work to improve the teaching and learning of mathematics in Victorian schools

@pwharris I know both of those numbers have 7 as factors 14 and 35 then becomes 2 and 5 There are 100 parts in a percentage so 100/5 = 20 2 x 20 = 40 Therefore 14 is 35% of 40

@MathsCirclesOz Thanks for sharing Michaela! We are currently looking at embedding 'predicting' in maths. This is a perfect example.

Check out "What's the question?" It's great for strengthening mathematical reasoning. How it works: 1. Take a standard problem from the current topic 2. Present Ss with only the answer to that problem. Ask: What's the question? 3. Invite Ss to solve one another’s questions

@mathsplay_org I notice the number of sections in each circle increases, and wonder if there is a pattern we can find to describe what is happening

Maths in the wild! What do you notice? What do you wonder? What's happening here? #MathsPlay #Maths #Play

@pwharris I know 100 x 36 = 3600, therefore 25 x 36 is 900. 900-36 = 860 + 4 = 864

@pwharris 5 x 32 = 160 5 x 160 = 800

Digits... was thrilled to hear about this game from a student today who challenges her friends each day. nytimes.com/games/digits

@MathsCirclesOz We had a play around with this today. One student ordered the numbers from smallest to biggest to figure out that -2 would be a good fit for the middle

Can you make each line add to -1? Use the numbers shown. What other combinations are possible? How do you know when you've found them all?

@mic_epstein @MathsCirclesOz Oooo good pick up! It seems that up until, n/0 is the point which the increasing pattern switches to a decreasing one. Interesting... reminds me of gradients.

@s_hellessey @MathsCirclesOz This is interesting. One edit to what you've got: n/0 is undefined. Does that change what you're thinking?

The fraction in this triple are all in size order. Does this work for all fraction triples with the same structure? How do you know? Share your strategy! For great maths teaching ideas straight to your inbox, sign up at: mathsteachercircles.org/sign-up/ #MTCoz #MTBoS #iteachmath

Happy International Day of Mathematics! Students enjoyed creating maths jokes, a scavenger hunt, decimal place and free hand circle competition, and telling us some Pi facts for a party pie.

Me listening intently to Colin below. Stepping back into the classroom today and instantly thinking how I can adapt and enhance my practice.

@DavidKButlerUoA I love it too! Thank you for the awesome activity that is now in our problem solving lessons at my school.

We got to play Digit Disguises at #100factorial yesterday. Gosh I love this game so much! blogs.adelaide.edu.au/maths-learning…

@MathsCirclesOz I'm noticing a spiral pattern and am wondering how we might make the spiral more evident. Maybe we can continue with the patterns of squares or look at drawing curved lines inside the squares from corner to corner

Take a look at this grid of squares... What do you notice? What do you wonder? What are you motivated to do next? For great maths teaching ideas straight to your inbox, sign up at: mathsteachercircles.org/sign-up/ #MTCoz #MTBoS #iteachmath

@DavidKButlerUoA Sorry, two student for each learning area.

@DavidKButlerUoA Yeah, pretty awesome! I believe this is the third year we have had them. Yes, there is one for each learning area.

Related to this, if you’re a school teacher, what would you hope kids got from a maths activity at a university / provided by a university? #mtbos #mathschat
