This resource consists of two interactive excel files dealing with some aspects of construction and geometric proof.
Perpendicular Bisectors...
Golden Ratio
This series of excel interactive sheets look at the golden ratio.
The first two sheets investigate the ratio of each pair of consecutive terms in the Fibonacci series, and what happens to the ratio as the sequence...
Gradient
This excel program contains a series of interactive spreadsheets designed to explore the concept of a gradient of a curve.
The first activity illustrates that the gradient of a function, at a point P, is the gradient...
Gradient
This excel program contains a series of interactive spread sheets designed to explore the concept of a gradient of a curve.
The first activity illustrates that the gradient of a function, at a point P, is the gradient...
Graphical Solution of Equations
This resource is an interactive excel program to enable students to investigate the solution of polynomial equations up to cubics using a graphical method.
The program shows the graphs of cubic equations and the...
Graphical Solution of Equations
This program allows students to solve pairs of equations by drawing 2 graphs and looking at the points of intersection. The graphs can be cubic, quadratic or linear. The 1st interactive sheet allows students to plot pairs of graphs by changing the coefficients of y=ax...
Growth and Decay
This resource is an interactive excel program to enable students to investigate exponential growth and decay. The topics of the interactive sheets are depreciation, exponential growth of bacteria and half life and radioactive decay.
...HCF and LCM
The first interactive sheet shows a table of pairs of integers for students to reveal the factors and sets of multiples. The HCF and LCM can be revealed. New pairs of digits can be shown, either easy or more challenging. Each number is shown as the product of its prime...
Histograms
This is a series of interactive excel sheets that look at histograms.
The first sheet contains a histogram displaying a summary of time spent travelling to work. A new set of data can be generated at the click of a...
Hyperbola
This program begins with graphs of the hyperbola in the form x2/a...
