It’s Easter time again, so time for an annual update – some Mathematical Easter treats!

**Also a post for students **– a **puzzle from Mathisfun** which is just an excuse to solve some simultaneous equations (and how to do it on Excel with the neat MINVERSE function!) The post also includes some notes and examples for students on simultaneous equations.

Easter Relay – Chris Smith

From Chris Smith, try his great Easter relay and note the **whole set**. I have used many of these very successfully – have fun whilst doing plenty of Maths!

On Teachit Maths, we have an Easter Chick with** ****Easter Coordinate Pictures** and **Easter Bunny Race**. With Easter Bunny Race, watch a race between the Easter bunnies and determine their speed. I like the questions to check understanding, including some harder questions – watch those units!

**Teachit Maths**, a (very good value) subscription site offers its **entire collection of activities** as pdfs free. I have found many high-quality resources here for all ages, including **older students** (KS5, 16-18).

Look out for **Easter Challenges from Perton School Maths Department**.

…and **here is the first challenge**:

WolframAlpha, of course, can show you some **graphs of Easter eggs!**

- Darth Vader on WolframAlpha – select image

I have noticed whilst using WolframAlpha random suggestions of queries popping up that somebody out there thought I might enjoy (very worrying how right they are!); **this** popped up – typing, for example, Darth Vader curve into WolframAlpha gives you just that! And my favourite **Dilbert and associates** are all there too!

On the subject of Easter eggs, I must return to **this definition. **An updated edition of…

**WolframAlpha – a little fun! **

From an Easter post some time ago, Douglas Butler created this Easter Egg in Autograph, just enter:

x²/4 + y²/4 + 5z²/36 = 1

and: r = z + 3.5

An Easter present for your students – why not give your students a **calendar from Just Maths**, so they can do a little bit of Maths each day…?

Or try these **highly rated TES Easter resources**, including some **countdown to GCSE Maths calendars**.

Happy Easter to educators and their students everywhere!
