Me; "Hey Kids! Do you know what you get when you add all the odd numbers from 1 to 19?" Me: "100...and, oh by the way, it's in the shape of a square" Probably the least known, but most beautiful idea of "100". #MathRecessChat

1, 2, 3 ... is out! This is a round up of maths stories reported via social media paper.li/GNMH_MathsHub/… Stories via NRICH maths

This week, we used #Numicon to help crack #perimeter with missing information. #whatitaughttoday Oxford Primary

Despite budget cuts, a new member if staff joined the team for next year.

Treats for next year.

Great fun meeting my new class in transition lessons today... feels like a transfer window!

Base 10 cubes are a useful #resource when talking about measure. Helps to address the common misconception of why numbers get smaller as the units get larger #whatItaughttoday

Happy holidays teachers!

What’s the largest even number you can make with these cards? How do you know?

Great fun today moving up and down number lines to explore #negative numbers #whatitaughttoday

Came back round to this idea today. Can’t stress the importance of learners’ #understanding and #coherence of the method to help to use it flexibly. #whatitaughttoday

Drawing on careful #variation within #questioning to help expose what is happening. Draw the attention of your learner to key patterns and concepts this way. #whatItaughttoday

Do not underestimate how careful #variation within teaching can help develop a systematic approach from learners to conceptual understanding. #whatitaughttoday

Using examples and non-examples to help consolidate the language of #fractions today.

Theme for this week's posts: purposeful variation. Drawing attention to specific aspects of the mathematics, helping children to make new connections. Give your thoughts, share your own examples, improve my ideas... Would love to develop a discussion!

Which one doesn't belong? #wodb

Every odd number has the letter 'e' in it.

Now finished I See Reasoning for Y5 and Y6 (both out Sunday). Between them, 758 tasks (compared to 176 from I See Reasoning - UKS2). But more than that, so many new ideas and techniques that I've picked up over the last few years: garethmetcalfe.wordpress.com/2020/08/28/why…

Also important is using non-examples for assessing understanding.
