Calculators

NAEP provides two on-screen calculators, which are available in calculator-enabled blocks in math and science.

  • The TI-108 is provided at grade 4 for math and at all grades for science.
  • The TI-30XS is provided at grades 8 and 12 for math.

Both calculators are sized such that their buttons are 46px tall to ensure they adhere to the minimum size specification for Touch Targets.

Both calculators are accessed by selecting the Calculator button in the System Toolbar. When toggled on, a calculator will appear at the upper-left corner of the content area, regardless of its position when it was toggled off.

Both calculators can be dragged within the visible content area when the test taker clicks and holds or taps and holds the calculator body. (To avoid potentially conflicting actions, calculators cannot be dragged by their buttons.)

Calculators appear on top of all other content. They are not allowed to overlap the Equation Editor, though a calculator and the Equation Editor can be on-screen simultaneously. Calculators are automatically toggled off when the test taker activates the scratchwork tool.
