Valentine’s Day, send Mobius Hearts our Way!

4 Feb

Valentine’s Day, not everyone’s favourite day, we show our numbers love and respect everyday of the year. However we will celebrate and share the number love with our students in class this week too.

Mobius Hearts

Great way to introduce topology and the idea of mobius strips to pupils, finishing the lesson of with these fantastic mobius hearts. The 360blog here gives a step by step guide to making your mobius hearts. Take a good look round 360’s blog and don’t miss the pop-up Sierpinksi Valentine’s cards here, all about fractals.

Heart Constructions

Follow this instructional video to construct a perfect heart using a compass and pencil, not for the feint hearted!

Choose your words carefully!

Mr Buffington explains why we should beware telling loved ones they’re one in a million.

Wow check out this blog What Teachers Want by a teacher called Rachelle and Natalie, this post has some great valentine maths ideas. Rachelle and Natalie’s blog is jam packed with free printables, not all mathematics activities.

Here you will find the Valentines Math pack, great for key stage 2 pupils.

TSM have given us the equations to our hearts to create this graph. It is worthwhile having a look at the TSM website here, it’s full of great resources and links to some of the best websites in the world. We are honoured to be part of the list TSM, thank you very much!

Create your own beating heart using matlab, guide here on Walking Randomly’s blog, or check out the demo here. Why not display this on your interactive whiteboard and see who takes an interest.

Your best ever investment – A puzzle box

2 Feb

The best gift I have ever received (from numberloving co-author Sharon Derbyshire as it happens) is my puzzle box. And yes, this is exactly what you think, a box full of puzzles.

This little box is a life saver at the end of term if like me you refuse to put on Miss Congeniality, or for all those times when for whatever reason you end up having a twenty-minute lesson, or only ten students in the class, or your IWB goes into melt down and you’ve got no board pen… I could go on.

Students love playing with these puzzles and it is time spent well for lots of reasons, so here’s the numberloving wish list for your very own puzzle box

1) Tantrix

This is my favourite puzzle game, you have to fit together hexagonal shaped pieces so that they form loops of different colours. The pieces are very tactile and there are lots of options for play depending on the difficulty you want, these are well worth the investment.

2) Impuzzable cubes or the Bedlam cube

These are loved by students and they will be surprisingly patient in their approach, they basically have to fit some 3d shapes together to make a cube shape. This is great for their spatial awareness and understanding of volume.

3) Rubix Cube

This is obviously a favourite of the students but they will spend forever twisting it around and not getting anywhere so to make it worthwhile teach yourself how to solve them (there are lots of websites with simple methods – I use the layer method) and then you can teach the students the strategy.

4) Sudoku

Print and laminate and allow students to solve using whiteboard markers. If you are really organised then print them onto different colours depending on the ability. Check out our archives for a blog all about Sudoku and beyond!

5) Frog Puzzle

We have all heard of the puzzle where the three frogs on the left have to swap places with the three on the right, print and laminate instructions and some frog pictures (or I bought some little frog toys off ebay). You can even get them to find the pattern as the number of frogs increase and work out the nth term!

6) General Number Puzzles

This is a brilliant set of general number puzzles, I can’t remember where I picked it up. Print and laminate and away you go. You can even use these as starters or weekly form time puzzles.

7) Pentominoes

Print and laminate these pentominoes and get students to try and fit them together in a rectangle, there are lots of potential solutions but it may be worthwhile printing sections of some solutions to help them get started.

8) Wooden puzzles

These and lots of others can be found on www.puzzleguru.com where they are classified by difficulty which is very helpful!

Ebay is also a great place to find some of these puzzles for those of us on a budget. Any other ideas for additions to my own puzzle box would be much appreciated, get puzzling! Get in touch @numberloving and check out our TES NumberLoving Store for free and premium resources.
