Body Surface Area and other fun tasks!

24 Mar


One of my absolute favourite websites for practical lesson ideas is teach maths. It is full of free lesson plans across the whole curriculum, more importantly all of the lessons are hands on and practical. So far I have tried two lessons from this site, both of which have been brilliant!

The first of these is on body-surface area, the plan is available here. Basically students have to calculate the surface area of their body. In order to do this they have to split their body into different shapes (I show them the slide above for inspiration) then they take the necessary measurements to calculate the surface area of each shape. This has a lot of real-life applications, the most interesting being calculating doses for things like chemotherapy. Once they have an answer there is a formula which the medical profession use, they can apply this formula to see how close their estimates are.

The second lesson is on discovering the formulae for the volume of a pyramid, the lesson plan is available here. In this lesson students construct six pyramids which they fit together to make a cube. They can then see that the volume of one pyramid is one sixth of the volume of the cube, a bit of algebra later and hey presto the formula for the volume of a pyramid is discovered!



Both of these lessons have worked really well for me, students have been really engaged and more importantly have been forced to think for themselves. Along with these lessons are many other brilliant ideas which I can’t rate highly enough, well worth a look.

Four Pictures One Maths Word

17 Mar

Inspired by Reflective Maths blog here and Mr Collins post here I got my thinking cap on and came up with the following maths versions of the latest craze!


All of these can be downloaded for free, get it here; 4pictures1word

It would be great to hear your thoughts or suggestions on improving the four pictures and/or sharing your ideas!

Exam Warm Up Revision Resources

17 Mar


Only a matter of time till the next exam series and I decided to build in mini-revision to each lesson between now and then. Hence the birth of Number Loving’s differentiated exam warm up resources for both Higher and Foundation students.

Set 1 of the higher exam warm up exercises can be downloaded from here
Foundation; Warm Up F SET 1Warm Up F SET 2Warm Up F SET 3Warm Up F SET4
Higher; Warm Up H SET 1Warm Up H SET 2Warm Up H SET 3Warm Up H Set 4

***Please note these don’t reflect the new 9-1 curriculum!!***

Each set has five warm ups designed to be used in each lesson for that week. As always these are differentiated by colour indicated by the post-it notes; red (easiest), amber (medium), and green (more difficult). The topics remain the same, for example on the foundation set 1, day 1 shown above you will see the green question about missing angles in isosceles triangles. This bottom left hand question is always about isosceles triangles in set 1.

Display one on the board at the beginning of each lesson, giving pupils a small copy to complete as soon as they arrive to class.

I hope you find these resources useful in the lead up to exams!

Easter Mathematical Activities

16 Mar

Last year we blogged about some of our favourite resources to use at Easter time (read the blog post here) a lot of these resources, and others on the web, are aimed at KS2 or lower ability KS3 students. So this time around I have designed four activities aimed specifically at secondary students;

In the first activity students have to use their skills of adding and subtracting fractions to ‘collect the Easter joke’. The questions are increasingly difficult; starting with common denominators to finding common denominators, to adding and subtracting mixed numbers.

In the second activity students have to use angle properties of parallel lines, isosceles triangles and angles in polygons to calculate missing angles and then shade in the grid to create a picture of a basket of Easter eggs.

The third resource pupils have to find the mode, median or range from a list of numbers, final questions require the evaluation of algebraic terms first.



Finally in the last resource students have to rearrange the functions to the form y=mx+c in order to identify the gradient. Again this is a Math At activity and pupils will shade all the squares with that answer.

These could be used with KS3 and KS4 students and could form part of the lesson or be set as a homework task depending on how you get students to approach them. Instructions and ideas for support and extension are given within each resource, the solutions are also given at the end. If you like these resources you can check out our other resources in our TES store here.

Check out Whieldon’s mini mystery here or below is an example of a free Mathematical mystery.
