Here are five games which situate retrieval practice of number facts and strategies within a bigger, meaningful context. We've enjoyed playing across a broad range of ages levels and can attest to curiosity they spark through play. https://t.co/GaIydEVOYJ #Maths #Play #MTBoS

Exciting times ahead. If you’re a new teacher or experienced teacher or leader looking for a change in 2025, please come along to our Recruitment Information Session. Can’t wait. https://t.co/tkdj478EfM

Australian primary school teachers have strong preferences for using non-digital games over digital games to support maths instruction... and not because they are Luddites :) @tobyrusso @kath_cartwright @mminas8 @helenjwc @leicha @JBayWilliams

To prove this Max says take the example 3&10. Multiples of 3 in base 10 will end in every base 10 digit. From there you can add multiples of 10 to get any other number. You can generalise this to work with any two numbers, if you show it in the base of the larger number.

My 13 y/o had this idea (‘Max’s theorem’). For any 2 co-prime numbers m&n, if you add only multiples of m&n the max number you can’t make is always <mn. Above that you can make every other number. Does it work? Is there a pattern to the maximum number? @littmath @standupmaths

‘Over Under On’ is a super fun & simple game we introduced in our article on different types of whole-class math games. A great way to explore probability and introduce game theory. Check out the full article here:

I’m back teaching a problem-solving type course, this time for primary pre-service teachers. What are some of your favourite problems to help develop skills in thinking and working mathematically? I’d love to encounter some new ones.

Primary teachers: Looking for a whole class place value game focussed on connecting representations and mathematical reasoning. You might want to check out Guess My Number: Two Questions and a Clue @tobyrusso @kath_cartwright @10001angela @helenjwc

In case any teachers in the Melbourne area are looking for some end-of-term (affordable - $35) professional learning focussed on digital maths game @GervasoniAnn and I are running a full day PL at AMCI on Monday 11/9. Register here: https://t.co/Tp6z2fbRIp @tobyrusso @maths_vic

This is a chart of the percentage of 8 and 9 year old students who are still using the count-on from larger strategy when solving addition problems. Two different student groups are being compared. Can you guess the groups? If you’re interested: https://t.co/5LgOuMK6jm

We are going to try and post more games during 2023. The first is Fishing For Tens, which is incredibly easy to play and great way to help kids develop fluency. All you need to play is a regular deck of cards. Enjoy! https://t.co/wT5D4vPaW9

Best thing I learnt today, the ISS travels 1000 miles in the time it takes The Proclaimers song ‘I’m Gonna Be (500 miles)’ to play. Thanks @xkcd https://t.co/b3MZTCsR4V

Oh @surfmaths and @tobyrusso have I got a awesome investigation for you! The new Skittles bag says “3 x bigger!” My girls already have a looong list of ways we will investigate this so stay tuned!! But what questions does this prompt for you?! #noticeandwonder

This pattern revealed itself when I was working with a group of grade 5 students on a fraction problem. It may be obvious to many, but I learnt something new! Can you see what we found? I assume this rule has a name? #iteachmath #MTBoS

An engaging task for exploring prime and composite numbers. Here arrays are not just a 'thinking tool',but are at the heart of the task. How many stones might you ask the old man for? How many gold coins could you earn? @tobyrusso @mminas8 @kath_cartwright https://t.co/ASu93SepaY

Support students to develop a relational understanding of the equals sign through playing the card game 'the same as' in your classroom. The game can be easily adapted for different year levels. @tobyrusso @kath_cartwright @helenjwc @mminas8 @Corovie
