What is congruency? ***** Understanding congruency *****	Look at the animation and read the text. Click on the menu at the bottom to see more animations and definitions. Click and drag the red points to rotate, translate and reflect these triangles onto each other.
Congruent triangles *****	Click SSS. Make a blue triangle then make a red triangle. Why are they the same? Repeat using SAS and AAS.

Shape:

Cubes Rectangular prisms Triangular prism Hexagonal prism Pentagonal prism Platonic solids See-through solids **	Click and drag each solid to spin it. Count the edges, vertices and faces. Platonic solids have regular faces. In 'See-through solids', choose a solid from the drop-down menu.
Virtual isometric drawing ********	Click on a colour, then click on a line to draw these solids.
Solid shapes in the environment ****	Slide your mouse over the picture to see the solid shape outline. Read the name of each shape.
Rotating houses *****	Rotate the shape until you match the correct view
Line symmetry in 2D shapes *	Can you see a pattern?
Line symmetry *	Click on 'fold' to see how the shape folds.
Rotational symmetry *	Click on 'play' to see the animation.
Print and play (basics) Print and play (diagonals) Name the red figure **	Print this table, then click on red points to move the quadrilaterals. Answer the questions on the paper. Print this second table and play with the quadrilaterals. Answer the questions on the paper. Drag the blue quadrilaterals around. Name each red figure inside them.

Interactive shapes *****	Click on a shape, then click and drag the red points. Answer the questions. Note: The first one takes time to download!)
Floor Tiles *****	Change the square by dragging its vertices, then click 'Tessellate'
What is a fractal? * Koch snowflake ***** Sierpinski's Triangle *** Plant fractals	Look at the pictures. Fractals repeat themselves. Click 'next stage' to see the snowflake change. Read the sentence at the top. Click 'next stage' to see the triangle change. Read the sentence at the top. Draw plants using fractals.

Measurement:

Triangle Explorer **	You can visualise and calculate the area of different right-angled triangles with a grid background.
Area of a triangle ****	Calculate the area of each triangle. Write your answer and check.
Area of a trapezium **	Use your calculator and the formula for the area of a trapezium, then check your answers against the computer.
Area of a circle **	Enter a value, then use your calculator and the formula to check your answers against the computer.
Composite area exercise *	Do these exercises to revise for your test. The computer will check your answers.
Squaring the Triangle *	This is Pythagoras' Theorem. Drag the triangle and use a calculator to check that the areas of the 2 smaller squares add to give the area of the biggest square.
Pythagoras' theorem *	Use a calculator to check your understanding of Pythagoras's theorem.
Area of a rectangle *******	1 Click on 'Only draw rectangular shapes'. 2 Drag the slider to adjust the perimeter. 3 Click 'Draw new shape'. 4 Calculate (or count) the area of the rectangle. 5 Click 'Draw new shape' and repeat. How many rectangles have the same perimeter?
Perimeter explorer *******	Investigates the perimeter of rectangles with the same area. (Click 'only draw rectangular shapes' and then adjust the area.)
Shape Explorer *	This gives you a grid, so you can practise your area and perimeter.
Surface area and volume *****	Click on the prism and drag it around to see each side. Each rectangular and triangular prism has grid lines on it. You can change their dimensions.

The number plane and graphs:

Bar graph sorter **	Can't draw graphs? Try this one! It's easy and fun.
Crazy coordinates *****	Plot and name points in the first quadrant and other quadrants. When you are right you are given a diamond, when you are wrong you get a lump of coal.
General coordinates game **	Name and plot points in four quadrants.
Planet hop game *****	Use this game to become more familiar with naming and plotting points in four quadrants.
y = mx + b *** Slope slider ******	See how the gradient, m, and y-intercept, b, affect the graph. Change the values yourself. Use sliders to change the gradient and y-intercept of a straight line, as you watch the equation change.
Bath time with Archimedes *****	Click on the tap, click the plug, click Archimedes and watch the graph change as you play with the water level.
Graphing program *******	Type an equation you want graphed. Use the carat key (^) to type powers. Click Zoom to change the scale.
Moving man *****	Choose one graph first. Click and drag the man across the screen. Drag him slowly, forward or fast and backwards. Watch the graph. (Choosing two or three graphs is more difficult to understand.)
What is a function? **	End of level 2, or level 3 students, can read this easy-to-understand definition of a function.
Function Machine **	Can you guess the function? Check your answer with the computer.
Conic Flyer *****	Helps you visualise families of graphs when you change various pronumerals. Use the drop-down menu to draw parabolas, circles, hyperbolas and ellipses.
Data Flyer *****	Enter a function, then click 'set function'. Move the sliders to see what happens to your graph when you change parts of your equation. This graphing program also has a trace feature. You can also plot data here. You must use the usual keys such as * and ^ to make operations work.
Winplot*****	Download this free, but very powerful graphing program.
