|-

|-
|[[Image:TA-setxy.png]]||Setyx (xcor, ycor)||move turtle to position (xcor, ycor) [(0, 0) is in the center of the screen.]
|-
|[[Image:TA-seth.png]]||Seth (heading)||set the heading of the turtle [0 is towards the top of the screen.]
|-
|[[Image:TA-text.png]]||Text (size)||draw text next to the turtle

|-
|[[Image:TA-xcoor.png]]||X coordinate||holds current x-coordinate value of the turtle (can be used in place of a number block)
|-

Turtle state values (can plug into a parameter):
* X, Y – Zeros for each are at center screen. Negative values are left and down; positive values are right and up.
* Heading – Zero is pointed up. Heading is in degrees clockwise.
* Angles are degrees from 0 to 360 (for larger values and smaller values all multiples of 360 are subtracted or added to get the value into the range 0..360).
::Examples: 90 means a right angle (90 degrees), clockwise; –30 means a 30-degree angle, counterclockwise
