Input to program the amount of time that RVR+ will execute a movement like a roll or a spin in seconds.

Input to program how quickly(or slowly) a Sphero robot will move, usually in centimeters per second.

A sensor that measures RVR+’s x-axis, y-axis, and total distance from its point of origin, in centimeters.

1. A sensor that checks the light intensity from 0 - 100,000 lux, where 0 lux is full darkness and 30,000 to 100,000 lux is direct sunlight.

1. A sensor that measures the numerical RGB value of any color that is directly underneath the sensor on RVR+.

A sequence of characters that combine letters, numbers, and other characters in a computer program.

Allows you to define conditions by comparing two values (usually a sensor to a number).

Calls the “if” blocks if the given condition is true, otherwise calls the “else” blocks. These are known as the If/Then or If/Then/Else blocks.

1. The action of repeating over and over again, either indefinitely, for a set number of times, or until a condition is met.

Conditional logic called when the color sensor reads a given RGB value, defined as 0 to 255 for the red, green, and blue channels. The color for this block is set using the color sensor on the Sphero RVR+.

If Math is after Science,

and Science is after Social Studies,

then Science is between Math and Social Studies.

If Wendy's sells spicy chicken nuggets,

and McDonald's sells spicy chicken nuggets,

then spicy chicken nuggets are sold at both Wendy's and McDonald's.

If my dog goes for a walk before breakfast,

and my dog eats breakfast before playing with toys,

then my dog goes for a walk before playing with toys.

If I have a dentist appointment on Monday,

and I have have a haircut appointment on Wednesday,

then my haircut appointment is after my dentist appointment.

If December is colder than November,

and November is colder than October,

then November is the coldest.

If the blue blanket is warmer than the red blanket,

and the red blanket is warmer than the green blanket,

then the red blanket is the least warm.

________________ allow you to define a reusable group of blocks, and then call those block from anywhere within the main program.
