Math Animations (Grades 1 vs Colour Tiles by mathies

Great way to "see" how math works! --by Greg Garner Awesomely Effective!!! An absolutely amazing and brilliant way to visually demonstrate basic math principles! Thank you! -- by iPad Dad3 Math Animations : mathematics animations. The animations provide short, sharp, visual explanations of mathematical concepts. Who is it for? It is for everyone interested in mathematics. It is principally designed for upper primary and lower secondary teachers to use in the classroom, but students interested in deepening their understanding of core concepts will also find the site useful. Animations: 1. Addition 2. Addition Table 3. Subtraction 4. Subtraction Table 5. Multiplication 6. Multiplication Table 7. Division 8.

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
