The mechanism : The green outer ring with 5 primary partitions and and 300 smaller partitions gives 59/300 turns per minute counterclockwise: 11.8 turns per hour. The planetary gear of the seconds, in green color, is driven by the outer ring and gives 59 rph counterclockwise. And in turn, the axis makes a complete turn clockwise, rolling on the inside of the crown of the minutes, by hour.

The hand of the minutes, in blue color, turning on the central axis and linked to the axis of the planetary gear of the seconds, makes a complete turn every hour. The wheel that rotates clockwise integrally with its base and with the hand of the minutes, make to spin counterclockwise two blue planetary wheels.

Simply Fractions 2 is designed for second grade to fourth grade elementary students to further their understanding of fractions, it is the next step from the Simply Fractions app.

Kids will learn about mixed fractions, equivalent fractions, fractions on a number line, a fraction of a collection whose size is greater than the denominator, compare fractions with different numerators and denominators, but can be compared to either 0, 1/2 or 1. We use a scaffolding approach, where the concept is introduced visually first, later there will be games without visual aid to strengthen the concept learned. The full version has eight different mini activities.

The lite version has 2 mini activities, no ads are served in either versions.Here is a summary of the activities:1. 6. 7. 8. No kids should feel dumb because they don't understand math, many times we fail them because we let them learn the next concept before they grasped the first concept.

The wheel that rotates clockwise integrally with its base and with the hand of the minutes, make to spin counterclockwise two blue planetary wheels.

These two planetary wheels spins counterclockwise a third planetary gear. The third planetary wheel rotates one turn per hour clockwise and transmits the rotation to the fourth planetary wheel.

Camera patchwork. The application allows true 360 degree views:The program builds the image using a projection of the sphere similar to Mollweide. (Like COBE spacecraft images) From the beginning of the picture, you can get up to 180 degrees left or right.Beyond this limit, the images are placed in the right place.You can also reach up to 90 ° up or down.Along shooting, you can move the starting point dragging on the screen. (Be careful with this) The images are constructed from 300 small images.The camera takes a picture when it detects a new spin 8 degrees in either direction.Move the camera slowly.You can stop it before it has taken 300 pictures.We recommend vertical sweeps, moving to the right or the left.The created images (*.jpg of 3840px * 1920px) are stored in the SD folder: /CameraPatchwork/ Cinemice - Nummolt - MathCatsCamera Patchwork gallery: Cinemice - Nummolt - MathCatsCaméra galerie Patchwork:
