This example demonstrates the low temperature in degrees Fahrenheit (°F) on Monday, Tuesday, Wednesday, and Thursday in one town during a week, visualizing temperature data on a number line. The core math concepts involved are inequalities and data visualization. It is constructed using GeoGebra commands/objects like stepMax, stepper, steps, counter, text0, xmin, xmax, ymin, ymax, Randomized, button1, R1rel, R2rel, R3rel, R4rel, R1, R2, R3, R4, Problem, Monx, Tuesx, Thursx, Wedx, Monday, Tuesday, Wednesday, Thursday, text1, text2, text3, text4, text5, text6, text7, R1word, R2word, R3word, R4word, etc. It is suitable for middle school and above, teaching temperature data representation and inequality applications.
