Algebraic Expressions (1)
This interactive Java learning tool, which was constructed using the cross-platform open educational resource GeoGebra, allows a teacher to demonstrate and explore evaluating algebraic expressions with students. Choose from four algebraic expressions and use sliders to select the value of the variable (-10 to 10) and any parameters. Show or hide the algebraic expression, the expression with substitution, the notation shown for multiplication or division, and the result. Values range from -10 to 10 and can be integers or intervals of one tenth.
