### Note:

The HTML5 version of this tool was developed in August 2021. There are some differences between the newer HTML5 version and the version available for download from the App Store or Google Play Store but the core functionality remains the same. This support page was developed based on the downloadable App version of the tool so the images and instructions may not match the HTML5 tool perfectly, however, it still contains many useful examples.

## Mathematical Concepts

Represent various money amounts by dragging realistic images of Canadian coins and bills from the cash drawer to the workspace.
Use this tool to:
• estimate and count a collection of money
• skip count using the value of one of the coins or bills
• represent relationships between coins and bills (e.g., there are 8 quarters in a toonie)
• understand composing and decomposing numbers by building various representations of the same amount
• compare representations of different amounts of money
• develop operational sense
(e.g., add and subtract money amounts by making simulated purchases and providing change)
• explore place value and unit conversions

The cash drawer multiplier and multi-select copy features support students in
demonstrating multiplicative thinking and using anchor values of 2, 5, and 10.

Bank notes images used with the permission of the Bank of Canada.

Access a wide variety of Annotation tools to communicate thinking.
Insert pictures into the tool.
Work created in a mathies tool can be saved and opened. A saved file can be shared with peers or submitted to a teacher. The file will contain all solution steps from start to finish.

Take a screenshot to use as part of a portfolio, presentation, web page, etc.

### Connecting Fundamental Math Concepts with the Money Tool

Fundamental Concepts and Skills (Link #4) Tool Connections
Working with numbers:
Understanding and using numbers (e.g., being able to read, represent, count, order, estimate, compare, compose, decompose, and recompose numbers).
Money can be used to:
Recognizing and applying understanding of number properties:
Understanding how numbers behave in operations and drawing on that understanding to master math facts and perform calculations.
Money can be used to:
• demonstrate the commutative property of addition by combining groups of currency in different orders
• demonstrate the commutative property of multiplication by arranging currency in different arrays (e.g. 2 rows of 5 toonies vs 5 rows of 2 toonies)
• reinforce the associative property of addition as students represent and count currency in various ways (e.g. group all the currencies of like denomination then determine the total)
Mastering math facts:
Understanding and recalling math facts, using a variety of strategies.
Money can be used to represent math facts and illustrate various strategies.
Developing mental math skills:
Doing calculations in the mind, with little or no use of paper and pencil or calculator.
Using visual tools when learning to perform mathematical operations allows students to draw on these mental models and visualizations to perform mental calculations.
Money can be used to:
• demonstrate various addition and subtraction strategies
(e.g., to determine \$6.55 - \$1.95, add 5 cents to each value and determine \$6.60 - \$2)
• demonstrate various multiplication and division strategies
(e.g., to detemine 3 x \$5.18, represent three groups of \$5.18 then determine the value of each type of currency 3 x \$5 + 3 x \$0.10 + 3 x \$0.05 + 3 x \$0.03)
Developing proficiency with operations:
Performing calculations with ease, precision, and consistency and with a general understanding of number and operations, number properties, and their appropriate application in problem solving.
Students might use the money tool to represent and then solve various problems.

## Features of the Tool

(Note: The HTML5 version of the tool includes many, but not all of these features and employs a slightly different user interface.)

Button Description

### Labels

Show or hide the labels indicating the value of each currency.

### Change Units

Set the units of these labels to indicate dollars or cents.

### Choose Currency

Determine which currencies to place in the cash drawer.

### English / French

Switch between English and French text and currency formatting.

### Currency Size

Decrease / increase the currency size.
On mobile devices, pinch to zoom is also available.
On some desktop browsers, the mouse wheel can be used to change the currency size.

It is helpful to begin by setting the desired size of currency.

### Annotation Tool

Hide / Show a wide variety of Annotation Tools which can be used to communicate thinking.

### Insert Image Button

Insert images into the tool. More details.

### Undo / Redo

Step backward or forward through the actions taken with the tool.
This feature is not only useful for backtracking when a misstep is made, it enables a student to demonstrate their work from the start to the finish. The student can press Undo until they are at the start of their solution and then press Redo repeatedly, explaining each step.

Note: Undo / Redo is not available for annotation objects.

### Reset

Delete all work and return the tool to its starting state.

### Information

Shows a dialog with a link to this support page, a feedback form as well as copyright details and version number.

### Settings

Shows the settings dialog.

The Auto Size Annotation setting is selected by default. This means that if the currency size is changed, any annotation in the workspace will be scaled to match.

Use the Restore Defaults button to restore all the settings, including labels and which currency is available in the cash drawer.

Open, Import and Save files (see File Operations for more details)

### Currency Count

Check to see how many of each type of currency are in the work space.

### Number of Copies to Drag

Set the number of copies to drag from the cash drawer.

### Recycle

Click to remove selected items from the work space;
click again to clear the entire work space.
Alternatively, drag items to the recycle bin to remove them.

### Copy

Make a copy of the selected objects.

### Multiple Select

To selected currency draw a marquee rectangle around it.
Hold down the SHIFT key when drawing a marquee rectangle to add to the previous selection.

Click a coin or bill to add to or remove from the selection.

Selected currency can be moved, copied, or recycled as a group.

## Keyboard Shortcuts

On the desktop version of this tool, all of the standard Keyboard Shortcuts have been implemented.
 + increases the currency size - decreases the currency size

Video Transcript

Video Notes:
• This video was recorded using version 1.0.0.
• The above "How to" video does not include information about how to use the cash drawer multiplier, undo/redo, currency count, copy buttons, multiple select, image import and language features.
• The overlap setting has been removed. Currencies no longer mysteriously bounce back to the cash drawer.
• Coins and bills can be placed anywhere in the work space, even directly on top of each other.
• Increase / Decrease currency size buttons have been changed from left / right arrows to standard up / down buttons.
• The annotation video referred to in the above "How to" video is currently in development.
