- Figure It
- By Martin Goldberg
-
-
- Introduction
- ------------
- Figure It is aimed to give an insight into different sorts of number series.
- It explores Prime numbers, Fibonacci Series, Square numbers, Triangle
- numbers and multiples of any number up to 100. All this information can be
- seen graphically on a number grid - the size of which can be defined by the
- user. It is aimed at Key Stages 2, 3 and 4, Attainment Target 5 (Number).
-
- It gives factual information on any individual number; including all of the
- above plus the prime factors of the number, whether it is odd or even and
- whether it is perfect. All of these terms are explained within the program.
-
- All this information can be saved in a variety of ways by the user for
- inclusion in further investigations.
-
- To encourage children with multiplication tables and understanding the
- concept of factors and multiples there is a game of 'connect 4' that is
- played on a 10x10 grid.
-
-
- Screen Layout
- -------------
- After starting the program by double-clicking on the program's icon
- there will be a brief start-up screen followed by the main screen
- layout. The screen is divided into three main sections. On the left of
- the screen is the current menu, which is displayed as a set of icons.
- The middle of the screen is the current number grid. At the bottom of
- the screen is an information bar, showing the current status of the
- program.
-
- The initial size of the grid is 10x10, with numbers running from 1 to 100.
- This can be altered at any time during the program.
-
- The menu system is very straight forward. Each menu has a name which is
- displayed in the information bar at the bottom of the screen. The menu's and
- their associated sub-menus are described below. You may move back to the
- previous menu at any time, by clicking on the "⇦" icon at the bottom of each
- menu.
-
- In order to move around the number grid at any time you can simply click on
- the "⇧" and "⇩" icons at the side of the grid. To make a number the current
- one, simply click on the number on the grid.
-
-
- The Menus
- ---------
- There is one main menu which leads to various sub-menus, in order to control
- the program. The menu options are described below in the order they appear
- on the screen.
-
- GRID
- This option allows the pupil or teacher to alter various aspects of the
- current grid. The first 2 options allows the user to change the width and
- height of the grid respectively. The 3rd icon allows the user to 'jump' to
- a specific number on the grid, making that number the current one. This can
- save a lot of time moving around the grid with the arrow keys. The final
- option clears the displayed grid of all markers and multiples. It does not
- effect the current size of the grid.
-
- NUMBER SERIES
- This allows you to display various different kinds of number series on the
- grid. These can be displayed concurrently or separately and are all toggled
- on or off by clicking on the respective icon.
-
- The series that can be displayed include: Fibonacci, Prime, Square and
- Triangular numbers. A small coloured mark will be displayed on the grid next
- to any numbers that are in the series.
-
- Multiples of any number (2-99) can also be displayed by clicking the (X's)
- icon. These are shown as blue numbers and are toggled on or off in a similar
- way to above.
-
- HELP
- Clicking on any of these icons explains the various mathematical terms that
- are used within the program. Just experiment to see what information is
- given.
-
- GAMES
- See the Game of Fours below for more details.
-
-
- Save to disc
- ------------
- This is a very flexible option that allows the information within the program
- to be saved to disc. The information is saved to the same directory as where
- the program was loaded from. Therefore, if you are not using a hard disc, the
- floppy disc that contained the "!FigureIt" application must be present in the
- drive to avoid any errors.
-
- The information saved is for a specific range of numbers. The default range
- is 1 to 100. This can be changed at any time, the biggest range is 1 to 1000.
- The range chosen is independent from that displayed on the grid.
-
- For example if the range is set at 50-300 and the SQUARE numbers icon is
- clicked, all the square numbers that lie within this range, along with
- general information about each number, will be saved.
-
- In order to save general information on ALL the numbers in the current range,
- choose the INFORMATION icon (i). The facts saved are equivalent to what
- appears in the status box for individual numbers.... see below.
-
- The actual grid (with all its current settings) can be saved as a drawfile.
- This is very useful to prepare worksheets or just to display the pupils
- investigation. The other information is saved as a standard text file.
-
-
- General information
- -------------------
- The information given includes a list of the factors and prime factors of the
- number; plus whether the number is: Even, Odd, Prime, Square, Triangle or
- Perfect.

- The Game of Fours
- -----------------
- After clicking on the dice, you can select whether to play the computer or
- another human player. Once this is done you will be presented with a new
- menu, showing the 4 different levels of the game. Select a level according to
- ability:
-
- Level 1: Multiples of 2,3,4,5 and 10
- Level 2: Multiples of 3,4,5,6,7,8,9,10,11 and 12
- Level 3: As above, but including square numbers
- Level 4: As level 3 with the addition of prime numbers
-
- Each player takes it in turn to have their go. If you have opted to play
- against the computer, it will always go second. The object of the game is to
- place four counters in a row, either horizontally, diagonally or vertically.
-
- On each go you are asked a question. Once you know the answer simply click
- the number on the grid. If you are correct a coloured counter will appear. A
- wrong answer has no effect, simply keep trying until you are right.
-
- The strategy is simply to prevent your opponent getting a line of four,
- whilst trying to make your own line of four. The computer plays fairly
- intelligently, but due to the element of chance in the game, anyone can win!
-
- You can quit the game at any time by clicking on the "⇦" icon. Note the
- game's position is not saved; therefore, if you return to the game later on
- you will have to start from the beginning.
