It is nearly Pi Day, March 14th (3.14), so to celebrate try some of our resources from the seasonal Pi Day bundle. This bundle consists of three resources described below.

**Pi Day Relay Race**

A set of 16 relay race questions suitable for able KS4 pupils. The questions are progressively difficult, starting with the basics (see picture) to solving problems involving area, circumference or volume.

Print one set of questions for each group on different colours. Each group has a team captain, they retrieve the question from the front , taking it to the team to answer. Once they are confident they’ve got it correct they return it for marking. If correct they get 10 points and the next question. If they are wrong they can have a second attempt for 9 points.

**Pi Day Collect a Joke**

The pupils must calculate progressively difficult fractions of amounts (suitable for KS3 pupils), each answer gives a letter spelling out the punchline to the Pi Day joke. This resources includes ‘red herrings’ for quick self and teacher assessment. This resource is free to download as part of try before you buy!

**Pi Day Mystery**

Pupils are challenged to use the clues to plot all five circles and find the point of intersection. They will need to use and inverse the formulas for the area and circumference of a circle, as well as some Pythagoras’ Theorem.

Each resource includes instructions, ideas for support/extension and solutions.

All three are available in our Pi Day bundle

Like a lot of teachers I spend a fair amount on things to support my teaching. For example, the smelly stickers from PTS are a favourite of mine for using as rewards. However, without a doubt the best buy I’ve made so far is my Hue HD webcam. This may seem expensive at £39.90, but considering I use it every day it has paid for itself time and time again!

It’s basically a webcam, but it has a weighted base and an adjustable arm so it works really well as a visualizer. You install the software (this takes a couple of minutes) and then simply plug in via the USB connector. I use this on a daily basis and it really is brilliant! Here are some ways I use it:

- Pick a student at the end of the lesson and display their work. Get the class to assess it and feedback. This is an instant plenary, it exposes misconceptions, promotes discussion, encourages good presentation and much more!
- As an extension get a student to write an exam question on the topic you’ve been doing. Then just put their question under the webcam and you’ve got your plenary sorted.
- Display an exit ticket from the previous lesson and get students to find the mistake as a starter.
- Display students’ exam responses and get pupils to mark them.
- Use after marking books to showcase really good work or a mistake lots have made.
- Use when teaching constructions (or measuring angles etc.) so pupils can physically see you doing it.
- Use to display a nice question in a book which you only have 1 copy of.

The webcam also has a little button on the top which takes a picture, so you can save their work, tweet it, email it to a parent – whatever you fancy!

**‘<3’ Is a HEART,**** composed of two parts. **

**In Mathematics, **** this means “less than three”.**

**Because in real life, LOVE has no space for a third,**

**Love is only you and me!**

It is that time of year and both NumberLoving authors are feeling the love with two weddings to plan, so here are some more math Valentine’s Day activities!

**Mathematical Valentine Rhyme Challenge**

Challenge your pupils to write a mathematical rhyme including a set number of mathematical terms. This is a great idea I found on Craft Moms share blog here and the example on the left is taken from their blog and includes 7 maths terms. I will be challenging my pupils to come up with their rhymes for homework! Check this one out, not by a pupil but still a great poem!

We have a number of Valentine and love themed mysteries, in which pupils use the clues to solve the question. Mysteries are a thinking skills activity in which pupils use the clues to solve problems. Check out our post Pi Day

**Also not to be missed;**

Check out these blogs for great valentines maths ideas;

Googol power bring a wide variety of activities, I love this activity finding the area and perimeter of hearts. Pupils estimate and for extra challenge ask them to calculate. Even better get pupils to use Desmos as described in Colleen Young’s blog here to create their own heart, math-o-gram. Then ask pupils to find the area and perimeter.

One of my favourite activities making heart shaped mobius strips and other great ideas in our blog “Valentine’s Day, send Mobius Hearts Our Way” for other valentine maths activities.

Make Sierpiński sieve pop heart with instructions from 360 (don’t be put off by the dinosaur).

Speed dating with data collection in this blog we describe how to set up a speed dating activity allowing for data collection.

So who will be your math-en-tine?
