Instruction Guide: EV3  My Blocks
This lesson introduces students to the concept of My Blocks  the EV3G equivalent of a subroutine. Have students watch the "My Blocks" video from EV3 Trainer.
In this Lesson we have 1 Primary Instruction Resources:
 The resource is an EV3 Trainer lesson on My Blocks.
Have students work through the EV3 Trainer describing My Blocks:
Behaviors > Bonus > My Blocks
Students should be able to answer all the review questions at the end of each step and end up with a solid command of the use of My Blocks
The Task Assessment Sheet for this lesson is open ended. Students are asked to revisit a previous challenge with repeating blocks, and rewrite the program using My Blocks. For example:.

Have students resurrect their program for Sensabot Challenge (in Moving Straight)
 Identify repetitive sections of their program and implement My Blocks to simplify

If students used the Color Sensor to determine both when they reach a line and then when they leave a line, they will have the most elegant solution.
 if students used rotations or time to get off the line, then their program will not be as compact  encourage them to make the change now

Have students resurrect other challenges
 Identify repetitive sections of their program and implement My Blocks to simplify
 Have students develop a new challenge that takes advantage of My Blocks to simplify what would otherwise be an unwieldy program
If students are expected to use Flow Charts to plan/design their program (which is encouraged), it may be useful to also go through the upcoming Advanced Flow Charts Lesson. This lesson introduce the concept of a SubProcess, which is the Flow Chart equivalent of a My Block.
