Learning Objectives

  • CCSS.MATH.CONTENT.4.G.A.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

Guiding Ideas

To begin class show the short video on lines, rays, and segments. Then ask the students these questions

1) What is a line?

2) What is a ray?

3) What is a segment?

4) Compare and contrast lines, rays, and segments?

Student Activities

Step 1 Code the Dropper with the /fill command

Have the students watch the video on the fill command held in the first NPC. It is important that the students build their droppers at least 40 blocks away from each other so their droppers do not overlap, yet do not have them go so far away they can not see each other or have trouble returning to the NPC videos. I like to say build with some elbow room but stay in sight of the example dropper.

Write the fill command in big letters on the board, remember

1) all letters need to be lowercase

2) there is one space between tildas (~)

3) there is no space between tildas and numbers (~19)

/fill ~ ~ ~ ~19 ~59 ~19 sealantern 0 hollow

Step 2 Put in Your Points

Have students watch the video in the 2nd NPC on points. Have students build and label several points inside the dropper.

Step 3 Put in Your Lines

A line is a straight edge that extends to infinity in both directions. Have students watch the video on lines and then send them to their dropper to build parallel and perpendicular lines as obstacles. Lines inside the droppers will extend from wall to wall.

Step 4 Put in Your Rays

A ray is like a line but has one endpoint and will extent to infinity on only one direction. Have the students watch the video on rays and build and label them inside their droppers. Build the ray from a wall to a point the student has put in during step 2.

Step 5 Put in Your Segments

A segment in a line cut off at two points and will not extend to infinity. Have the students watch the video in the NPC. Then they will build and label segments between to points that they made in step 2.

Step 6 Finishing Your Dropper

Have the students build a landing pool at the bottom of the dropper then they will need to put in an NPC to reset the game. Code the NPC with a teleport command

tp @p ~ ~59 ~ make sure the NPC is not under a starting hole so the player has something to stand on when they teleport up. Test the NPC and teleport to the roof.

Once on the roof create a “Start Game” NPC and code it with two buttons

Button 1) Start Game

gamemode 2 @p

spawnpoint @p

Button 2) Done

gamemode 1 @p

The “Done” button will put the player in creative mode so they can fly to another dropper.

Step 7 Play Test

Last once the game has been coded play your dropper until you beat it. If your game is too hard remove some of the obstacles inside. Once a player beats their game it will be open for others to play and the player can try other droppers.

Performance Expectations

1) The student was able to name, define and identify points, lines, rays, and segments.

2) The student was able to code a working dropper.

3) The student was able design a challenging yet beatable dropper game.
