Generates a 3D co-ordinate axes by adding an extra dimension onto a 2D gird. Demonstrates how to plot 2 co-ordinates in three dimensions and considers this as the diagonal of a cuboid. Hover the mouse over the pink and orange triangles and press 'play' to see them in two dimensions. Click the covers to reveal the lengths. Extends to generalising the longest diagonal of a cuboid and includes some exam style questions.

Scroll through the first few slides to introduce a cuboid (hover over the pictures to reveal the properties and click on the boy pushing over the rectangle to revel transform a rectangle into a cuboid). Break down the layers of the cuboid examples by clicking on the x, y, z buttons to see the layers separate and questions students on the associated multiplications and the commutative properties of multiplication. When the cubes can't be seen, hover over the faces of the cuboid examples to reveal the cubes and click the covers to reveal the answers.

I've always struggles to show students how subtraction works as a balance as it can't be visulaised, until now!Keep the balance of the scales by adding or subtracting content from both sides. Do this by clicking on the 1's or x's at the top to add on and on each side of the balance to remove them. Pop the balloons by adding weights to both sides (sound effects included!)

Scroll through the examples and press 'start' to start the event scrolling up and down the probability scale. Invite students to the board to click the screen to stop the even in the correct position. Revel the fraction using the buttons and split the probability scale into fractions using the 'fraction' button to see if the even it accurately placed. Includes student activity worksheet.

Initially, click on the lego bricks to break them down into smaller percentage proportions. Once all 6 base blocks are revealed, click on them stack up the required percentage. Scroll through the examples and uncover the base building blocks by cliking on the covers. Once all base builing blocks have been revealed, build the required percentage by clicking on each block to stack them up.

Dynamically change the problems in this PowerPoint using the up/down buttons. Click on the +/- symbol to add or subtract the equations and click on the green area to see the equations combine. Reveal the solutions by clicking the covers.
