• More numbering options! Label the number line with fractions or decimals. Hide or show negative numbers on the line. • Jump to locations on the number line that can’t be reached by scrolling: tap the Go To button next to the scrollbar at the top of the workspace. • Label the top of a custom tick mark, not just the bottom: just drag the tick mark’s text box to the top of the number line. This is great for showing equivalence or comparing values with numbers below the line. • When entering fractions with the text tool, they automatically convert to the stacked fraction format.

Many new features and enhancements: • More number line types: choose an open number line with or without tick marks. • Custom tick marks: add a custom tick mark to an open number line and enter your own values. • New option to label jumps with custom values when working with open number lines. • Jumps flip when moved below the number line for better display when comparing sequences of jumps. • Easier object selection: select multiple jumps or text by lassoing them with one finger on the background. Use two fingers to scroll or use the new scroll bar at the top of the workspace. • Expanded drawing and text tools: a new straight line tool and more color choices. • Duplicate tool: duplicate jumps, text, or custom tick marks.
