Lowest common multiple and highest common factor (LCM and HCF)

Lowest common multiple and highest common factor (LCM and HCF)

An interactive PowerPoint that uses prime factor trees and Venn diagrams to model how to calculate the LCM and HCF. Uncover the end branches by clicking on the covers, click on the end branches to select the prime factors, show the Venn diagram and click on the selected factors to place them in the Venn diagram.

Placing probabilities and fractions on a probability scale (Interactive)

Placing probabilities and fractions on a probability scale (Interactive)

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.

Balancing Equations with subtraction (interactive balancing)

Balancing Equations with subtraction (interactive balancing)

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!)

Interactive Percentage of a Quantity building

Interactive Percentage of a Quantity building

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.

Cuboid volume (interactive layering)

Cuboid volume (interactive layering)

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.

Pythagoras and trig in three dimensions

Pythagoras and trig in three dimensions

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.

Solving by iteration (trial and improvement). Fully dynamic and interactive.

An interactive PowerPoint to model solving quadratic and cubic equations using trial and improvement. Use the +/- buttons on each row to change the input and click on the x number shown to watch it dynamically substitute. Click on the blank parts of the table to reveal the substituted parts evaluated. Using the +/- button on the next row, modify the input and substitute again by clicking on the number shown and repeat the process. If more table is needed, click clear.

Lowest common multiple and highest common factor  using prime factors (interactive PowerPoint)

Lowest common multiple and highest common factor using prime factors (interactive PowerPoint)

Starts by finding LCMs and HCFs by listing and extends to using prime factors and Venn diagrams to calculate LCMs and HCFs. Scroll through the PowerPoint using the navigation buttons. Reveal the covered factor trees by clicking on the covers and click the end branches of each tree to select the prime factors. Once all end (prime) numbers have been found use the show/hide button to reveal the Venn diagram. Click on the prime factors again to place them into the Venn diagram. Click on the LCM or HCF to reveal the answers.

2D views of 3D objects

2D views of 3D objects

An interactive PowerPoint that models the three views of a 3D object. Use the navigation buttons to scroll through the examples and use the plan, side and front buttons to show the object rotate into the correct position. Before revealing, invite students to the board and ask them what the views might look like by clicking on the square grid. I have attached some questions also.
