Number Line, by MLC4.2.0 - App Store

Number Line helps students visualize number sequences and demonstrate strategies for counting, comparing, adding, subtracting, multiplying, and dividing. Choose number lines labelled with whole numbers, fractions, decimals, or negative numbers. Or use a blank number line, with or without tick marks.

Describe intervals between points on the line using forward or backward jumps above and below the line. Jumps can be labelled with their values or left blank. Add custom tick marks to the number line to show equivalence or compare number values. Show strategies with drawing and annotation tools.

Hide elements of the sequence shown on the number line, which challenges students to use what they know about number relationships and computation to identify those missing elements.

This virtual number line is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use iPads.

FEATURES

. Mark the number line with multiples of whole numbers, fractions, or decimals. In addition, set the starting value of the line, including using negative values.

. Add and manipulate forward and backward jumps, above or below the line.

. Label jump bars, manually or automatically, to show intervals or hide labels altogether.

. Add custom tick marks and values to blank number lines.

. Hide and reveal numbers on the number line.

. Hide and reveal jumps, numbers, and other elements with resizable covers to create your own problems and model strategies.

. Use the drawing tools to annotate work and show understanding.

. Add equations, expressions, and descriptions with the math text and writing tools.

. Share your work by saving an image or providing a share code to others.

Version History This version introduces a fixed palette with additional drawing and annotation tools: highlighter, rectangular and round shapes, variable line thickness, and arrowheads. 4.2.0 12/02/2023 4.1.0 Includes improved line setting customization of start and increment values, as well as support for up to 100 segments on the workspace. 4.1.0 08/04/2022 New features in Version 4:

• Share your work by saving an image or url, or providing a sharing code to others. Great for creating the initial setup of an activity, then sharing it with students so they can explore it further.

• Enter text directly from your keyboard with the new writing tool. Add labels, descriptions, or instructional text to your work.

• More easily edit equations and other math text using a traditional text field.

• Drawings on the workspace stay visible when the drawing palette is closed.

• Hide and reveal jumps, numbers, and other elements with resizable covers.

Version 4.0.1 includes a number of improvements and bug fixes. 4.0.1 09/09/2020 New features in Version 4:
• Share your work by saving an image or url, or providing a sharing code to others. Great for creating the initial setup of an activity, then sharing it with students so they can explore it further.

• Enter text directly from your keyboard with the new writing tool. Add labels, descriptions, or instructional text to your work.

• More easily edit equations and other math text using a traditional text field.

• Drawings on the workspace stay visible when the drawing palette is closed.

• Hide and reveal jumps, numbers, and other elements with resizable covers. 4.0.0 11/11/2019 More symbols added to the math text tool for writing equations and expressions.

Minor bug fixes. 3.1.8 01/26/2017 Minor bug fixes. 3.0.2 09/16/2016 • 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. 3.0 05/03/2016 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. 2.0 08/13/2015 1.0 11/22/2013
