#### Area and prism generator

An interactive geogebra applet that generates most shapes of interest including… ==&gt;triangles ==&gt;squares ==&gt;rectangles ==&gt;parallelograms ==&gt;trapeziums ==&gt;regular…pentagons,hexagons,heptagons,octagons,nonagons,decagons ==&gt;circles …at the press of a button (use the slider to change shape). Good for use with an interactive whiteboard to practice finding the area. This can then be converted into a prism using the ‘add layer’ button so that students can form the links betweeen area and volume. Keep adding layers to generate the prism or use the ‘generate prism’ button to generate a random depth prism. Each layer can be dragged away from the prism to justify mutliplying by the depth. You either need geogebra installed on your machine or use the web link to use the resource within a web browser without the need to install geogebra.

You can hide/reveal the multiplier in each questions as well as the answer. Please ensure you have geogebra installed on your machine or use the web link to show the applet in a web browser without the need of installing geogebra.

#### Interactive pythagoras question generator and solver

An interactive geogebra applet that generates pythagoras questions. Good for use on an interactive whitebaord or projector. You can generate random length problems at a press of a button as well as specific shorter side/longer side questions. You can hide/reveal the squares in each questions as well as the answer. Please ensure you have geogebra installed on your machine or use the web link to show the applet in a web browser without the need of installing geogebra.

#### Dicovering Pythagoras

An interactive geogebra applet that allows the teacher (or students on ipads/in computer room if uploaded onto geogebra website) to create right angle triangles using a set number of standard squares. Students can record their trials and try to spot any relationships between the size of the squares that work. An accompanying worksheet and lesson plan to match. You need geogebra installed (free) or use the web applet that does not require geogebra to be installed.

#### Probability tree generator

A dynamic and interactive probability tree structure generator. Generate questions and create the corresponding tree so students can practice interpreting questions. This is a geogebra applet so you need the application installed or use the web link so you can use within a web browser without the need of installing geogebra

#### Investigating Circumference and Diameter (Discovering Pi)

An interactive geogebra applet that enables students to investigate the relationship between the diameter and circumference by measuring the diameter (drag the blue cross), unrolling the circle and measuring the circumference (drag the red cross). Students can zoom in to inprove the estimation of pi. Please note, you need to install geogebra (or upload onto geogebra site for use without install).

#### Simultaneous equation creator and solver

An interactive geogebra applet that creates and solves two sets of linear simultaneous equations dynamically. Drag the vertical slider to reveal the working. Also shows the graphical significance of the solution in an additional window. You must have geogebra installed on your machine or use the web link to use this without needing geogebra to be installed.

#### Volume of revolution

An interactive geogebra applet that allows the teacher to plot any function and dynamically reveal the volume of revolution around the x-axis. It calculated the volume also.

#### Area of a Parallelogram

Models how to find the area of a parallelogram by linking it to the area of a rectangle. Fully dynamic and interactive examples.

#### Simultaneous equation interactive solving powerpoint

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.

#### Listing outcomes (probability of multiple events)

An interactive PowerPoint that simulates various simultaneous events by systematically listing.

#### Adding and subtracting fractions visually

An interactive and dynamic PowerPoint that models how to add and subtract fractions using pictures. Use the 'fraction' buttons to show the visual representation of each fraction and click on each sector to shade it in. Click on 'add/subtract' once to reveal the common denominator shape and again to visually see the fractions adding together.

#### Constructing Triangles (SSS)

A presentation demonstrating how to construct a triangle given all three sides.

#### Area of a Trapezium

An interactive PowerPoint that models how to calculate the area of a trapezium by dynamically converting it into a parallelogram.

#### 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.

#### Shape transformations (rotations, reflections, enlargements (inc. negative) and translations)

A big PowerPoint that is fully interactive and models both doing and describing all transformations. I have also added in a lesson plan for instruction how to use. Fully interactive with dynamic examples.

#### 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.

#### 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.

#### Creating designs with rotation symmetry

An interactive PowerPoint and worksheets that model how to complete/create patterns with rotation symmetry using tracing paper. Using the navigation buttons...1)Select the example, 2)Show the tracing paper, 3)Trace the design, 4)Rotate the tracing paper to find the missing parts of the design.
