Apps

Practise addition, subtraction, multiplication or division. For single operation games the unknown value is the result (e.g., 3 + 5 = ?). For mixed operation games the position of the unknown value changes (e.g., 3 + ? = 8). Players determine the unknown value and drag the glove to the correct answer on the number line.

Represent numbers, ratios and percents. Explore patterns and measurement. Create geometric designs. Users can change colours, create mirror images, rotate, and copy selections.

Represent, compare, order, and operate on whole numbers, fractions or decimals by dragging rods from the tower into the workspace and manipulating them. The colour scheme of the rods can be customized, including to a traditional and a primary palette which are similar to physical manipulatives.

Relational Rods+ includes:

• Relational Rods - rectangles of various lengths where each rod can be evenly subdivided by the smallest square rod, plus
• Whole Number Rods - rectangles of lengths 1 to 10 with numeric labels and dashed divisions on each rod, plus
• Decimal Number Rods - rectangles of lengths 0.1 to 1.0 with numeric labels and dashed divisions on each rod.

Additional features (v 1.2.5 June 2017):

• Save and Open files. Files contain all the steps performed; use Undo and Redo to see all the steps. Use iTunes File Sharing. Information about File Operations on Support Wiki.
• Traditional colour palette is now the default to be similar to physical manipulatives.
• Installers for Windows and Mac available for download.

Sets of objects can be generated randomly or designed by the user. Sort and classify objects. Create patterns. Represent, compose and decompose whole numbers, tenths, and fractions. Explore experimental probability.

Users can:

• organize objects using ten frames or frames of tenths
• scramble objects in the workspace
• create new sets while conserving count and the selected attribute options
