Shape : Area and Perimeter

Shape : Area Builder by PhET, Colorado University

This simulation allows pupils to explore the concepts of area and perimeter. There are two distinct modes to this game.

The first is great for exploring and teaching and allows squares to be dragged onto a grid and gives numerical values to both area and perimeter.

The second mode provides students with a set of challenges or puzzles to solve by setting targets for shapes with specific area and perimeter. It allows instant checking and feedback.

There are six levels of difficulty and most pupils will gain something about area and perimeter by using this simulation.

The higher levels encourage arriving at an area or perimeter by using calculations – an on screen calculator is provided.

This shape, area and perimeter project is created using HTML5 and as such will play on desktops and tablets equally well, including iPads.

Shape : Creating Squares

In this game, each player takes it in turn to put a dot on a grid. Whoever manages to deploy four dots that can be connected to complete a square is the winner.

The game can be for two players or a single player can play against the computer.

Once you’ve played the game a few times (and lost!) against the computer you begin to look for the strategies the computer is using to beat you and use them against your opponents.

Who knows, you might even beat the computer one day?

This game works well on tablets – even on my old iPad! A great activity to fill a few minutes at the end of a session or at the end of the day in the couple of minutes before the bell rings…

2d Shape : Shape Maker

2d Shape : Shape Maker

Suitable for all tablets. this game allows pupils to experiment and learn the names of a variety of 2d shapes. The game comes in two parts. Firstly the ‘Shape maker’ names a 2D shape and asks children to draw it on the virtual pin-board – immediate feedback is given.

Secondly there is the ‘Builder’, a simple drawing package that enables children to create images using provided 2D shapes. Each 2D shape can be resized and rotated and have its fill colour changed.

As a bonus any images created can be printed as well as named and saved as a .PNG file.

This works really well on my ancient iPad and would probably be suitable for pupils learning about 2D shape in the 5-9 age range.

This interactive activity explains the difference between 2D and 3D shapes. It allows them to explore 2D and 3D shapes and consider their properties.

There are 9 2D shapes in all and 11 3D shapes. There is also a simple worksheet in MS Word format that can be downloaded and printed.
