Represent and model operations with integers and polynomials. Tiles representing 1, x, x², y, y² and xy along with their opposites can be dragged into the workspace from the scrollable selection panel at the left. Once in the workspace they can be moved, copied, re-oriented, or negated individually or in groups. The tiles can be configured to match the colours of the physical manipulatives commonly available in classrooms. This virtual algebra tile tool also includes 1, x, and y line segments. Unlike the physical tiles, the value of x and y can be adjusted.

The Number Chart tool includes two number charts (0-99 or 1-100), an addition chart (to 12 + 12), and a multiplication chart (to 12 x 12). These charts are an ideal tool to support students as they develop fundamental math skills. Number charts offer versatile ways to explore relationships among numbers and develop math skills such as counting, patterning, problem solving, and using a variety of strategies to perform arithmetic calculations (including using related math facts).

A virtual manipulative similar to the physical ones commonly available in classrooms. Eighteen different types of blocks can be dragged into the workspace from the scrollable selection panel at the left. Once in the workspace, blocks or groups of blocks can be moved, copied, reflected, or rotated. The colour of each type of block can be changed. Blocks can be used to create designs and develop mathematical understanding (e.g., patterning, geometry, whole numbers, fractions and decimals).

Additional features (v 1.0.3 April 2019):

• Added three new rhombus shapes
• Improved undo/redo steps related to images
• Bug fixes

Use the Rekenrek to build understanding of whole numbers, number relationships, and strategic reasoning for counting, addition, subtraction and multiplication. Relate numbers to the anchors of 5 and 10. Use the annotation feature and imported images to communicate solutions.

Additional features (v 1.3.1 December 2018):

• minor bug fixes
• correct links to support pages
• addresses recent changes to the Google Play store

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. Use the annotation feature and imported images to communicate solutions. File Operations (Save, Open, Open from WWW and iTunes File Sharing) are supported.

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 2.1.0 August 2019):

Practise the fundamental skills of 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. At the end of each game, visual representations on the number line provide ways to think about the operation.
