Resource description 
Given the function and the input, find the output. Given the input and output, find the mapping.  
Given the nth term create the sequence and vice versa. Positive and negative linear sequences. Given a multiplier, create a sequence. Investigate the second difference. Quadratic sequences either create given the nth term or find the nth term.


Quickly generate linear sequences. Good to use as a starter with whiteboards  
Substitute with positive and negative numbers into expressions  
Substitute with positive and negative numbers into expressions with brackets and squares.


Substitution grids with a range of expressions including using negative numbers  
Substitute into expressions with brackets, squares and cubes. Identify what happens when you square and cube negative numbers.


Simple substitution into formulae for perimeter and area of a square, surface area of a cube and perimeter of a rectangle. 

Collect like terms in the pyramids  
Collect like terms in the pyramids  
Collect like terms in the pyramids  
Simplify expressions by multiplying together. Expand and factorise with a single bracket. Collect like terms with single letters.


Expand double brackets using the grid method. Questions with positive and negative numbers. Can also be used in reverse for factorising. 

Factorise quadratics with positives and negatives  
Solve equations of the form ax+b=c. Use flowcharts to solve problems with fractions and brackets. Solve equations with negative and fractional answers. Solve equations with unknowns on both sides. 

Solve equations by splitting up to find equal parts.  
Solve equations by balancing method  
Solve equations by balancing method  
Solve equations by balancing method  
Solve equations by trial and improvement. Involves equations with squares, cubes and roots  
Solve simple equations such as x+y=n and xy=n. Solve simultaneous equations using the same, subtract, substitute method when you always eliminate the x first.  
Solve simultaneous equations by elimination  
Solve quadratics that factorise into a single bracket, double bracket and the difference of two squares. 

Simplify expressions by multiplying, dividing and with brackets 

Calculate the value of k and the formula when y is inversely proportional to x and x squared  
Tables of value and graphs for lines x=n and y=n. Find the coordinates for equations y=x+c, y=mx and y=mx+c, or given the coordinates identify the equation. Given a pair of coordinates, calculate the gradient and the equation of the line.  
Find the equation of a straight line by identifying the gradient and intercept. Integer and fractional gradients  
Creates graphs and inequalities for students to identify the correct region.  
Creates multiple straight lines for pupils to solve by looking at intersecting points.  
Identify which straight line you must draw to intersect the curve to solve a quadratic equation.  
Use the graph drawn to identify the equation of the graph. Graphs in the form y=mx+c, y=x square and y=x cubed.  
Input numbers into tables of values for x squared, x cubed and 1/x. The graphs will be drawn as the numbers are input. Also table for quadratic graph.  
Identify equations of trigonometric graphs by looking at how the graph has been transformed  
A 3 stage distance time graph is displayed for question and answer session with a class. A 5 stage journey graph is also available.
