  • Recognize translations of shapes.
  • Find the objects in the environment that are translations.  
  • Orientation on 4 quadrant graph paper.  Quadrant one (x/y positive/positive), Quadrant two (x/y, negative/positive),  Quadrant three (x/y negative/negative), Quadrant four (x/y positive/negative).

Procedure

Vocabulary: translate, horizontal, vertical, coordinate grid

  • Review with student what it means to translate or slide a polygon on the coordinate grid. 
  • With the student using the Translation Worksheet find the polygon and record, using the student's media of choice, the coordinates of the polygon.
  • Slide (translate) the polygon by the following points (2,4). 
  1. Have the student choose one point to start the slide (translation)
  2. Move the point 2 units along the x axis
  3. Move the point 4 units along the y axis
  4. Mark the new point
  5. Continue until all three points have been translated
  6. Connect the three points
  • If the student is confident, have them then slide (translate) the same figure by the following points (-3, -2) or once again work with the student to slide the polygon.
  • When the student is confident, begin playing the game "Race to Earth".
