Free Printable Mapping Worksheets for Year 12

Ask students to represent the same function three ways: as an arrow diagram, a set of ordered pairs, and set notation. Then have them defend its classification by referring to the behavior of inputs, the outputs reached, and the stated codomain.

Use problems that require students to create and interpret mappings, identify domain and range, and classify functions as one-to-one, onto, or bijective. Include comparison tasks where two representations look different but describe the same input-output correspondence.

The most common mistake is declaring a function onto without checking the stated codomain. Students may also call a mapping bijective after proving only that it is one-to-one, or misread set notation and omit an input-output pair when converting representations.

A worksheet can be hosted as a digital quiz on Wayground or downloaded as a printable PDF for paper-based practice. Every worksheet includes a complete answer key, and teachers can grade printed submissions by scanning or capturing student work in the Wayground for Teachers app.

Mapping reflects the Common Core approach of interpreting functions through their relationships and representations. It builds on domain, range, and function notation, then supports later work with inverse functions, where a one-to-one mapping is needed for the inverse relation to remain a function.

Use wider font spacing or larger text to separate dense labels and arrows in printable versions. For digital work, extended time gives students room to check every input and codomain value, while Read Aloud can support learners who need help processing written directions.

Grade 12 students should be able to interpret and create mappings in arrow diagrams, coordinate representations, and set notation. They should also explain why a mapping is or is not a function and justify whether it is one-to-one, onto, or bijective.
