Games
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.
Learning Tools
Represent numbers, ratios and percents. Explore patterns and measurement. Create geometric designs. Tiles can be squares, circles or rounded squares. Users can change colours, create mirror images, rotate, and copy selections.
Additional features (v 2.0.1 April 2018):
- New annotation drawing objects (rulers, number lines, grids, hops and polygons)
- Annotation is scaled as tiles are resized, by default
- Save your work to files on your device (more details on Support Wiki)
- Open files stored on your device or from the web, including several example files
- Opened files contain all the tool steps performed; use Undo and Redo to review these steps
- Opened files contain the final annotation step which is not affected by Undo and Redo
- Switch between English and French

Represent fractions by dragging pieces from the fraction tower into the workspace. Pieces can be placed in a line to form a train. Manipulate the pieces and trains to compare and order fractions or to model fraction operations.
Additional features (v 0.8.0 May 2017):
- available for mobile devices
- includes annotation and image tools
- pieces snap to align; create vertical comparison bars
- pan and zoom the workspace
- move and resize the tower
- save work to a file and open from a file

Write solutions, sketch diagrams, import pictures, create graphs and record your mathematical thinking. Use one of four backgrounds: grid, isometric dot, lined or blank. Use built-in line, shape and text annotation objects, including number lines, rulers, grids and polygons. Copy and rotate any annotation object.
Additional features (v 2.0.0 December 2017):
- Save your work to files on your device
- Open files stored on your device or from the web, including several example files.

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 tools and imported images to communicate solutions.
Additional features (v 1.3.0 November 2017):
- new annotation drawing objects (rulers, number lines, grids, hops and polygons)
- copy and rotate all annotation objects

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 2.0.0 February 2018):
- New annotation drawing objects (rulers, number lines, grids, hops and polygons)
- Annotation is scaled as rods are resized
- Opened files contain the final annotation step which is not affected by Undo and Redo

Sets of objects can be generated randomly or designed by the user.
- Sort and classify objects.
- Organize objects using number frames (ten frames, five frames, frames of tenths).
- Create patterns.
- Represent, compose and decompose whole numbers, tenths, and fractions.
- Randomly scramble objects to new positions.
- Randomly create new sets of a particular size with specified attributes.
- Explore experimental probability.
Additional features (v 2.0.3 March 2018):
- Five frames
- Objects will snap into number frames
- Number frames can be moved, copied or rotated (along with all of their objects)
- The Auto Arrange button organizes objects into groups of 5 or 10
- Randomize Attributes buttons allow configuration of the attributes to change
- New annotation drawing objects (rulers, number lines, grids, hops and polygons)
