Bidmas Spiders

(19)
I needed something for my top set Year 8 to get their teeth into regarding "order of operations" and since I'm clearly into spiders at the moment this was born. It asks student to place operations and brackets into calculations to make them equal a certain total. There are 4 that get increasingly difficult (no indices involved) and then a challenge (with indices involved). There will also be more than one way to answer some, but I have provided an answer for each.

Rounding Spiders

(13)
A comment from my trainee teacher made me think that rounding to decimal places and significant figures needed an activity, so I came up with this. It should get students thinking and should open up discussion on rounding, which can be a little "dry" but essential to get to grips with. Typo corrected!
Surds SpidersQuick View
alutwychealutwyche

Surds Spiders

(12)
These spiders (there are seven of them in total) take you through simplifying, calculating, rationalising denominators, expanding brackets and rationalising "tough" surds.
Algebraic Expressions SpidersQuick View
alutwychealutwyche

Algebraic Expressions Spiders

(19)
Four "spiders" to help students become comfortable with algebra and manipulating expressions. There is an extension one at the end and the opportunity for discussion about whether there are many answers etc. I have left some blank ones for students to make up their own.
Average and Range SpidersQuick View

Average and Range Spiders

(21)
This should bring about plenty of discussion. Four "spiders" of increasing difficulty asking students to complete a list of numbers to make the average and range properties true. A couple of typos corrected.
Parallel and Perpendicular Lines SpidersQuick View

Parallel and Perpendicular Lines Spiders

(28)
With the new curriculum in mind I did this. Students must use their knowledge of parallel and perpendicular lines to fill in blanks but this could lead to discussions about different ways to write equations of lines etc. Errant negative signs on number 4 corrected (I hope).
Inequalities SpidersQuick View

Inequalities Spiders

(12)
This is designed to make students think about representing inequalities on a number line, listing integers (directly and having simplified) and regions. They are split this way to allow you to start/stop wherever you feel your class needs to. The number lines and graphs are as big as I can make them!
Speed-Time Graphs SpidersQuick View

Speed-Time Graphs Spiders

(22)
Three "spiders" containing increasingly difficult questions moving from just reading the graph through calculating distance travelled to calculating acceleration.
Calculus SpidersQuick View
alutwychealutwyche

Calculus Spiders

(17)
This covers basic differentiation, finding gradients at given x values but could be used to introduce integration plus moves on to negative and fractional powers of x. Could be used at Core 1 (or whatever they are going to call it when it changes) and with the new GCSE.
Expanding Brackets SpidersQuick View

Expanding Brackets Spiders

(22)
This takes students through expanding a single bracket, factorising a single bracket, expanding two brackets and factorising quadratic expressions. Hopefully this should lead them in manageable steps to factorising quadratics, including a few with the coefficient of x squared being greater than 1. When I find errors I have corrected them...
Distance-Time Graph SpidersQuick View
alutwychealutwyche

Distance-Time Graph Spiders

(12)
Three "spiders" involving three different distance-time graphs and questions involving read them and speed. Hopefully this has covered most, if not all possible questions from a distance-time graph.
Surface Area and Volume SpidersQuick View
alutwychealutwyche

Surface Area and Volume Spiders

(6)
Six spiders on surface area and volume (3 of each) and a final "problems" spider. They are of increasing difficulty, moving from cubes and cuboids to prisms to cones, spheres and pyramids. These are designed to avoid students getting into a rut of performing a mathematical recipe by asking a mixture of finding surface area/volume to working backwards. These usually encourage discussion in class.
Multiplying and Dividing Fractions SpidersQuick View

Multiplying and Dividing Fractions Spiders

(8)
Four sheets (two with mixed numbers, two without) to practise multiplying and dividing fractions. This is just a different way of doing some questions and depending on how it's run can involve plenty of discussion.
Trigonometry SpiderQuick View
alutwychealutwyche

Trigonometry Spider

(8)
Four trigonometry spiders: the first two involve right-angled triangles (one for finding sides and one for finding angles), the third involves non-right-angled triangles and the fourth involves 3D trigonometry. They should encourage discussion in class as they get more difficult from "12 o'clock" and moving clockwise.
Proportion SpiderQuick View
alutwychealutwyche

Proportion Spider

(7)
This covers simple direct and inverse proportion, including finding the relationship bewteen x and y as well as using the formula to calculate other values. Some challenge ones involve surds towards the end. Each spider has challenges for discussion when seeking solutions. Designed to encourage discussion.
Percentage SpidersQuick View
alutwychealutwyche

Percentage Spiders

(2)
This takes students through percentage of an amount, one number as a percentage of another, percentage increase and decrease (including multipliers), percentage change, repeated percentage change and the reverse. This should be more challenging as the students go through it and should produce discussion.

Maths Spiders Bundle

All these are available for free but if you want to download them in one bundle then this is for you. The activities ask increasingly harder questions as you go through and are designed to encourage discussion in class. I use them regularly and the students engage well with them.
Bearings SpidersQuick View
alutwychealutwyche

Bearings Spiders

(6)
Just the three "spiders" on bearings, of increasing difficulty. The final spider asks students if they can write the question based upon the information given which may lead to a nice discussion in class.
Indices SpidersQuick View
alutwychealutwyche

Indices Spiders

(4)
Fill in the blanks to simplify using the rules of indices. This should create some discussion in class regarding negative indices and how they could be written.
