This week's PoT features a few great resources for formulae, a superb blog about basic practice and racing snails...

This is the first Sunday I've been at my computer since my last Pick of Twitter, so there's a bit of backdating going on here. 

It's been a while since I last did a Pick of Twitter, which is personally quite annoying because it's my only way of chronicling all the good stuff I see on there - I'm going to try and get back into the habit on Sundays from now on!

It seems that we all do a bit of reflection at the end of the year. For me, my targets are a bit like New Year's resolutions - I start off well, but most things have fallen by the wayside by October half term. This year, I vowed to keep my room tidy and organise my equipment better... that didn't happen, and I must have bought about ten new boxes of pens from Tesco as pupils just wander out of the classroom with them. My first SBPC post was about just this - my What Went Wells and Even Better Ifs for this academic year.

As the staggered start to the summer holidays means that we all finish at different times (and yes, I am one of the lucky ones!), I'm reading a few great posts at the moment along just these lines. So today's post is a link to some of those.

Lots of brilliant stuff this fortnight! I'm adding all the fantastic lesson ideas and resources to the Resources by Topic index, but it's a very slow process. I'm hoping to get all the pages done for September 2015. I particularly enjoyed this week's #mathsTLP - I managed to miss the previous one as the bank holiday confused the days for me.

As I was away in London last weekend visiting a friend and completely not thinking about school, here's a fortnight's worth of Twitter picks!

• @Nat_Numeracy posted a great puzzle using Pythagoras' theorem for those people who found Cheryl's birthday too easy. 
  
• @PardoeMary posted a link to Visual Patterns, a site with a huge amount of scope for use when teaching sequences.
• @StudyMaths reminded me how useful the site is for quick practice questions, particularly at this time of year for exam revision!
• @solvemymaths made some great resources for geometric sequences following my plea for resources for new GCSE topics, and also provided me with a link to Euclid's Game (warning, it's addictive!).
• @DrBennison posted his mathematical journey, which I enjoyed reading very much. I am going to do my own at some point!
• @mathsjem posted this great joke for this week's #mathschat on "Funny or Punny Maths", with a reminder to subscribe to @aap03102's newsletter. 

• @mrbartonmaths posted a link to a fantastic BIDMAS murder mystery activity via the TES - I can't wait to try this one!
  
• This cute little rhyme from @CmonMattTHINK:

• And finally, I was really pleased and quite humbled to get a mention in @mathsjem's Gems #28, which also lead me to discover @Stacy_Maths's website, Miss Brookes Maths - resource addicts need to check her site out!
  

• @missradders ~ Link to a blog post from Disappointed Idealist about the issues with SATs resits; a very thought-provoking piece from a parent/teacher. Given that a significant number of pupils get to secondary school in Year 7 with real confidence issues with maths, I can't see that getting them to resit a standardised test is really going to improve that problem.

• @Kris_Boulton ~ Link to Tom Bennett's article on the TES about evidence based education research and the inherent issues with this. I found this really interesting to read on the back of last Wednesday's #mathschat "How to bring research mathematics and other research into the classroom?". 

• @srcav ~ Blog post about using incorrect examples of prisms and the problems this can cause. I admit, this had me checking some of my resources this morning! His posts about incorrect teaching of BIDMAS and rounding are also really good.

• @aap03102 ~ Interesting facts about Pythagorean triples, which reminded me that I need to do this similar investigation again at some point this year.

• Finally, this cute little comic from @spikedmath made me giggle a lot. I wonder if this could be the key to getting A Level pupils to stop mixing up sine and cosine graphs...

Got a whole fortnight's worth of stuff to fit into this post as Easter holidays mean I've had a little break from frequent Twitter checking! Here are my picks from the last two weeks:

Predictably, lots of the blog posts I've read this week have been about the third Maths Conference last Saturday. Having said that, it's great to read other people's perspectives and get an idea of what went on in all the workshops I didn't attend. Here's a few I've enjoyed:

• @BodliUK ~ 3 Techniques You Should Know, Mastery Assessment and Tricks and Tips.
• @DrBennison ~ Sticky Studying, Johnny Ball, Tricks and Tips.
• @Just_Maths ~ Interesting thoughts about thinking critically about teaching techniques.
• @naveenfrizvi ~ 3 Techniques, The Hows and Whys of how and why, Bar Modelling.
• @mathsjem ~ First blog post about her Tricks and Tips session with all the notes.
• @workedgechaos ~ Full summary of the day; his report on the Great Mastery Debate is really worth reading.
