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. mathsplay.org/blog/5-playful… #Maths #Play #MTBoS

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

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.

To celebrate Pi Day, we're posting a brand new game (that has nothing whatsoever to do with Pi)! The Mouse, The Cat & The Cheese is a @surfmaths creation and is a great way explore probability and addition. Please feel free to share with others. Enjoy! youtube.com/watch?v=RAShkqSL…

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.

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: researchgate.net/publication…

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! youtube.com/watch?v=NVH-tPV1…

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 what-if.xkcd.com/58/
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 researchgate.net/publication…

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 researchgate.net/publication…
