## Area and Perimeter Follow Me Cards

If you have never seen www.mrbartonmaths.com then you are seriously missing out! Mr B’s website is packed full of great maths teaching resources. These include some excellent ‘follow me cards’ for area and perimeter of squares, rectangles and triangles. I took this resource and slightly changed it so that the question and answers are not adjacent to each other on...

## It all began when a line met a circle…

I got a bit nervous this week. I had to teach my high-flying year 11s how to solve simultaneous equations algebraically when one is a circle and another is linear. This was the first time I’d taught this topic and one I foresaw as having many potential obstacles to them gaining a good understanding. It links so many areas of...

## Reality’s Riddle

How about watching this video presented by the great Marcus Du Sautoy in end-of-term Christmas lesson? Nice to let the kids see something a bit deeper than line and rotational symmetry. Broaden their horizons etc…

## Circles are awesome!

Circles are awesome! That is certainly true but it is also the name of a fantastic website showing how circumscribed circles can be constructed. You can also move around the points and see the effects on the circumscribed circle in real time. Visit the Circles Are Awesome website here. Why not work your way through the steps in the presentation...

## Stickman Angles!

I honestly cannot remember when or where this idea came into being but I do think it’s a good one! Check out the worksheet below which features stickmen drawings. The pupils have to measure all the angles in the drawings and then unleash their creative side by producing their own stickman drawings and measuring the angles.

## Angles in 2D shapes

Checkout this worksheet for a nice investigation activity into angle properties of 2D shapes. A nice way of managing this one is to get pupils looking at different 2D shapes and then to share their findings with the class. You can have a whole lesson following where pupils share their angle property findings. For example “what did the people who...

If you haven’t seen the SMILE resources you certainly should have! SMILE (Secondary Mathematics Individualised Learning Experiment) resources were produced and used from the 1970s onwards but don’t think that because they are old that their time has passed. There are some wonderful activities and worksheets in the collection. You can now download every one of the SMILE resources from the...

## Cartoon starter for conditional probability

There are some jokes that only true mathematicians get. My personal favourite is “why did the chicken cross the Mobius Strip?” Answer: “to get to the same side”!!! I tell this to all my top set classes and love it when you see about a third of the class get it, another third pretend to get it because the peer...

## Do the nonagon…

Do the nonagon? It’s a dance! Yes, a dance! Check out the video below to view an excellent lively song about the names of polygons. I’ll leave it up to you to decide what the dance moves are to go with it…

## Tangram Constructions Fun

A huge thank you to Mr S for this wonderful idea! Make a lesson on triangle constructions much more interesting by getting the pupils to create triangles that form parts of a tangram puzzle that they then go on to solve. Wonderful idea! Click here to download the resource

## Making 3D Shapes- Net this great resource!

Having a collection of quality 3D shape nets is vital if you are going to teach a topic about 3D shapes. Making 3D Shapes that features 12 nets of common 3D shapes. You can use these resources to teach lots of shape topics including nets, surface area, volume and also Euler’s famous formula F + V – E = 2. A...

## Making teaching units of measurement a little more interesting!

It’s interesting to find out what pupils already know about units of measurement. Many seem to have an intuitive feel for them through everyday experience but don’t necessarily understand the difference between metric and imperial units. As a useful AfL tool for finding out what they do know and to give them an engaging activity that promotes thinking skills you...

## Are your pupils creative enough to solve this one? How fast are the trains?

I’ve yet to find a pupil that can solve the problem below but what is lovely about this problem is that most pupils can access it and have some ideas about how to solve it. It hooks them but provides a real challenge to solve it. There are many methods you can use to solve the problem and it is...
