** Fraction Strips ** Use Fraction Strips to represent, compare, order, and operate on fractions. 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.


 * Mathematical Concepts:**

Create visual representations that help explore mathematical thinking related to: Take a screenshot of your work to share with your teacher or add to a portfolio. You can insert pictures into the Tool using the button. top
 * Understanding part-whole relationships
 * Representing, comparing and ordering fractions
 * Iterating a unit fraction by copying
 * Exploring the relationship between the number of equal partitions in a whole and the fractional unit (denominator)
 * Exploring equivalent fractions
 * Modelling operations with fractions
 * placing pieces beside or between each other, to combine fractions (addition)
 * removing pieces from trains (subtraction)
 * aligning trains to compare fractions with or without using comparison bars, including to find differences (subtraction)
 * copying strips or trains to model repeated addition (multiplication)

 **Examples** Represent unit, proper and improper fractions. Combine pieces into a train to model operations.
 * Representing**

Align trains using the built-in snapping. Zoom in for more precision. Rulers, when shown, will illuminate ticks in red if a piece ends exactly in that spot. Create a vertical comparison bar to track a position down from train to train. Adjust the height of the tower using the double-arrow button beneath it; use the scroll bar to access hidden fractions. Reposition the fraction tower by dragging using the dark blue area at the top.
 * Comparing**

The equivalence bar in the tower can be dragged to reveal equivalent fractions in the tower. The ruler can be shown, with steppers that change the fractional unit (e.g., from thirds to sixths), to assist with renaming fractions.
 * Exploring Equivalence**


 * Operations**
 * place pieces beside or between each other, to combine fractions (addition)
 * remove pieces from trains (subtraction)
 * aligning trains to compare fractions with or without using comparison bars, including to find differences (subtraction)
 * copying strips or trains to model repeated addition (multiplication)

Colours can be changed to match physical manipulatives, like Pattern Blocks. Images, like the one below of a shape created by the Pattern Blocks tool can be imported. Strips can be removed from the tower. Pieces can be made more or less transparent (Settings). Annotation tools to select, draw, erase, and create lines, arrows and shapes are available from the Pencil icon at the top of the screen. Add text using the text box tool. Change the appearance (thickness, transparency, colour, size) of objects created with the annotation tools. Copy any image or annotation object, just like you would a piece or train.
 * Customizing the Tool**


 * Ribbon Problem**

The grade 7 class is making decorations. They have 5 meters of ribbon to use. Each decoration takes 2/5 of a meter of ribbon. How many decorations can they make? Note: The video below was created with a previous version of the Fraction Strips Tool. media type="youtube" key="d_DvcE6IxAQ" width="560" height="315"

Multiple comparison bars can be created. The length of a bar, its colour and its thickness can be modified. || Zoom out to see more of the workspace. The fraction pieces will look smaller. On mobile, you can use the pinch-to-zoom gesture to zoom in and out. || Zoom in on selected pieces. The fraction pieces will look bigger, which is useful for more precise comparison, especially when working with small fractions. To pan the workspace use the scroll bars (desktop) or gesture with two fingers (mobile). || Re-orient the workspace so that all fraction pieces are on the screen. ||
