Resource Contents
Over the years we have recommended many mathematics resources which are available on the STEM Website. This post is a list of the resources with links to the appropriate post
1001 Math problems
Area puzzles 
A development of the ‘area maze puzzles’ first introduced by one of the world’s most prolific inventors of logic puzzles, Noaki Inaba 

Primes around six 
This resource has some interesting ideas on how to bring the distribution of primes into the secondary classroom. 

Cryptarithm puzzles 
A series of problems that test for understanding of place value and number properties. 

Geometric progressions 
Geometric progressions are often presented purely as a sequence of numbers but this resource uses graphical representations to bring the topic to life. 
Something in common
Crossbear 
Simple algebraic fractions and problem solving 

Four crescents 
Draws together work on area of a circle, composite shapes, Pythagoras’ theorem and algebra. 

Two crescents and a triangle 
Draws together work on area of a circle, composite shapes, Pythagoras’ theorem and algebra 

Train length

Brings together work on forming and solving equations, working with rates such as speed and manipulating fractions. 
Dy/dan
Marine ramp 
A resource to develop understanding of simple trigonometry 

Nanas Chocolate mix 
A resource exploring ratios 

Pixel Pattern 
This resource contains some interesting ideas on this topic and draws together work on sequences, rates, dimensions, ratio, coordinates and equations 

Bet your coffee 
This activity gives a chance to explore expected value in a context other than the usual ones involving games of chance. 

Domino sky scraper 
The dominos form a geometric sequence, with the dimensions of each subsequent domino increasing by a factor of 1.5. Which domino in the sequence would be sufficient to topple a skyscraper sized domino? 
MARS
Describing and defining triangles 
Recall and apply triangle properties. Sketch and construct triangles with given conditions. Determine whether a set of given conditions for the measures of angle and/or sides of a triangle describe a unique triangle, more than one possible triangle or do not describe a possible triangle. 

Describing and defining quadrilaterals 
The task explores how well students understand the definitions of various quadrilaterals. As an example, one question asks students if ‘all’, ‘some’ or ‘no’ rectangles are squares, and to give a reason for their choice of words. 

Building and solving linear equations in one variable 
To solve linear equations in one variable, collect like terms, expand expressions, and to categorize linear equations according to the number of solutions. 

Interpreting equations 
The resource is intended to help students connect algebraic equations to reallife situations. 

Interpreting and using data: setting taxi fares 
The resource is intended to assess how well students are able to select and use mathematical ideas to solve a problem and then compare and critique alternative approaches. 

Comparing data using statistical measures 
The resource is designed to help students make meaningful comparisons between sets of data. 

Angle theorems 
The resource develops conceptual understanding relating to the interior and exterior angles of polygons. 

Analysing games of chance 
The resource is designed to confront and overcome common probability misconceptions. 

Generalising patterns: the difference of two squares 
The resource is intended to assess how well students are able to work systematically, describe and explain findings, generalise, and explain why certain results are possible/impossible.
