The Mathenaeum. Exploring number The activities in this section are designed to promote an appreciation of numbers as products, the concepts of factorisation and prime factorisation, and to practice working with fractions. Much use is made of graphical illustrations of number value to help visualise the properties being investigated. Exploring geometry The activities in this section are designed to help in the investigation of properties of triangles, lines, parabolas and general concepts in coordinate geometry. Graphical and algebraic representations are provided where appropriate. By supporting both free and constrained manipulation of curves and objects, families of shapes and curves can be constructed and explored. Exploring algebra The activities in this section are designed to help build an understanding of algebra both as a natural extension of number, and as an efficient way of describing things mathematically.

Exploring chance & data Utilities Some simple and useful utility applications and puzzles. Mathimation | Maths and Animation. Interactive. Mr reddy dot com. Search. Advanced Data Grapher The Advanced Data Grapher can be used to analyze data with box plots, bubble graphs, scatterplots, histograms, and stem-and-leaf plots. Algebra Tiles Use tiles to represent variables and constants, learn how to represent and solve algebra problem. Solve equations, substitute in variable expressions, and expand and factor.

Coin Box Pre-K-2, 3-5 Learn how to count, collect, exchange, and make change for coins by manipulating coins using an array representation. Congruence Theorems Use this applet to prove the triangle congruence theorems by trying to create congruent and non-congruent triangles. Deep Sea Duel This strategy game requires you to select cards with a specified sum before your opponent (also available on iOS and Android). Dynamic Paper Pre-K-2, 3-5, 6-8, 9-12 Need a pentagonal pyramid that's six inches tall? Equivalent Fractions Factorize Dividing Numbers into Two Factors and Building Arrays to Represent Each Factorization Fractal Tool.

MathsPad. GeoGebra. Geogebra resources. Geogebra is a fantastic free piece of software you can use to enhance your pupils’ learning.

It combines the ability of graph-plotting with dynamic geometry. Think of it as Omnigraph and The Geometer’s Sketchpad in one program that is much easier to use, more intuitive and looks a lot better! For a great series of tutorials on how to get up to speed with Geogebra check out the Mathematics and Multimedia Gegebra Step-By-Step Tutorial Series. If you haven’t time to learn how to create your own teaching resources in Geogebra, but would like to use some of mine, please feel free to click on them below: Angle Theorems Angles around a point add to 360 degrees Angles on a straight line add up to 180 degrees Angles in a triangle add up to 180 degrees Angles in a quadrilateral add up to 360 degrees Vertically opposite angles are equal In parallel lines corresponding angles are equal In parallel lines alternate angles are equal In parallel lines interior angles add up to 180 degrees Circle Theorems.

Autograph Activties on Welcome to > autograph activities Welcome to a series of free, online, ready-made activities that I have written on a variety of topics using Autograph. You do not need to have Autograph installed to use these activities, you just need to download the free Autograph Player (full instructions contained within the activities). This means that pupils can use them freely at home, and teachers can use them on their interactive whiteboards or in computer rooms at school. I will be adding more of these activities as the weeks roll on, so keep checking back for more Graphing Co-ordinates and Lines Straight Line Graphs (y = mx + c) Quadratic Curves The Equation of a Circle Spot the Function Transforming Functions Conic Sections Calculus Shape and Geometry Transformations Shapes Angles Circle Theorems Pythagoras and Trigonometry Pythagoras in 3D Constructions Congruency Can you prove it?

Online converter - convert video, images, audio and documents for free. The Monty Hall problem. This program is a simulator for the Monty Hall Problem, as described on the Grand-illusion website . The simulator randomly positions the car and the goats in the three black boxes.

To start a run, click on one of the question marks. The simulator will then open a box with a goat in it. If you have chosen the car, the simulator will randomly select one of the two boxes with a goat. When you have done your second choice the simulator will reveal the content of all boxes and update the statistics to show the results for changing and keeping respectively. You can let the computer run 10, 100 or 1000 runs after each other. By checking Cheat the boxes will be marked with C and G to show where the Car and the Goats are. The clear button will reset the statistics to zero. Gdaviesmaths INDEX. Mathematics TopicBox. Interactive Maths - The Interactive Way to Teach Mathematics - Home.
