INSTRUCTIONS FOR USING MOREGRIDS.LGO


1.  If you are reading this using Windows Notepad, make sure you have activated Word Wrap (from the Edit menu).


2.  The file MOREGRIDS.LGO contains a number of logo procedures for use with MSW LOGO.  If you haven't got MSW LOGO then you are missing out on a very good package which is completely free.  
    It can be downloaded at
		www.softronix.com


3.  Start MSW LOGO.  From the File menu select Load.  Go to the location where you have saved MOREGRIDS.LGO, select the file and click on Open.


4.  The file contains procedures which produce a blank co-ordinates grid on the screen.
    Three different sizes of grid can be produced.
    Use the grid which fits appropriately on your screen.
    This will depend on the screen resolution you are using and the size of your monitor.
    To produce the grids, type one of the following in the Commander window and press Enter.
        SMALLGRID
        MEDGRID
        BIGGRID


5.  Once the grid is displayed on the screen you can plot any co-ordinates by typing in things such as
        plot 7 5
        plot 4 0
        plot 2.5 6.5
        and so on.


6.  The main purpose of these procedures is to enable the teacher to use LOGO as a teaching resource i.e. they are designed to teach pupils about co-ordinates, not to teach them about the LOGO language.  Use the procedures to introduce, demonstrate and discuss co-ordinates with the whole class (this is possible, even with only a 14 or 15 inch monitor, but a bigger monitor or projector is even better).

  
7.  Here are a few examples of the sorts of things you could demonstrate and discuss with the whole class.

    Produce a blank grid on the screen.
    Ask pupils what they think the numbers mean.
    Point to a location on the grid and ask pupils how we could identify or label it.
    Discuss the concept of a pair of co-ordinates.
    Use language such as 'axis', 'co-ordinates', 'vertical', 'horizontal', etc.
    Type the co-ordinates (e.g. plot 5 2) into the Commander window and press Enter (or get a pupil to do it).
    Repeat this by pointing at other locations on the grid.
    Also work in reverse i.e. call out a pair of co-ordinates and ask a pupil to come out and point at that location.
      


I hope you find these procedures valuable in your maths teaching.
Let me know how you get on.
