Tape Diagrams
• Can be used in the primary grades, all the way through
high school mathematics courses.
• Useful for helping students dissect word problems
• Can be used as a way to provide a concrete
representation for algebraic equations and
simultaneous equations.
• Fractions can also be incorporated into tape diagrams.
