Colour Tiles by mathies app for iPhone and iPad

Use colour tiles to represent numbers, ratios and percents. Explore patterns and measurement. Create geometric designs.

Mathematical Concepts:
Create visual representations that help explore mathematical thinking related to:
• Exploring number patterns and concepts
• Representing, comparing and ordering numbers, ratios and percents
• Skip counting by 2s, 5s and 10s
• Demonstrating multiplicative thinking
• Using anchor values of 2, 5, and 10
• Modeling operations with numbers
• Exploring rectangular areas and perimeters
• Investigating transformations including: reflections, rotations and translations

Features:
• Select a tile or set of tiles by drawing a marquee around them
• Copy, create mirror images, rotate or change the colour of selected tiles
• Change the size of tiles
• Use the multiplier button to set the number of tiles (1, 2, 5, 10, 100) to drag to the workspace
• Use the Tile Count button (#) to check to see how many of each colour of tile are in the workspace
• Step through a history of your work with the undo/redo buttons
• Communicate your thinking or highlight various features of your representation using the built-in annotation tool
• Insert background images
