2. Private Computer

If instead you want to use TheNumberLine.jl then proceed as follows.

1. Download TheNumberLine.jl
2. Open a terminal window go to the TheNumberLine.jl/src/ folder
3. Start Pluto.jl e.g. via julia -e "using Pluto; Pluto.run()"
4. In web browser window, select and open standard_number_line.jl

• To use TheNumberLine.jl on your own computer, you'll need to download Julia itself beforehand.
• to close the session you want to go back to the terminal window and Press Ctrl+C

1. Use a Slider

In the first code cell of standard_number_line.jl, where values are entered, you can use a list of a slider or multiple choice instead.

To do this, replace the line that says

` Type value : ` $(@bind b html"<input type=text>")

with

`Select value of x from the list : ` $(@bind b Select(["4","3","2","1","0","-1","-2","-3","-4"],default="0"))

or

`Choose value of x using slider : ` $(@bind b aSlider(-10:10; default=0))

2. Integers Only

To restrict the number line to using integers (as opposed to reals), try changing TestType in standard_number_line.jl.

To do this, replace the line that says

TestType=Number; NumberLineType=Float64; "Number LineType = $(NumberLineType)"

with

TestType=Int; NumberLineType=Int; "NumberLineType = $(NumberLineType)"
