Activity
Translate (Slide) that Polygon
This CCSS-aligned math lesson makes translating polygons accessible to students with visual impairments.
- 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).
- Race To Earth Game Board
- Cardstock Paper
- Space Craft Template (print on cardstock paper)
- Coordinate Cards (print on cardstock paper)
- Rules of the Game (attachment)
- Translation Worksheet
- Dots, Markers, Tape to Connect Dots
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).
- Have the student choose one point to start the slide (translation)
- Move the point 2 units along the x axis
- Move the point 4 units along the y axis
- Mark the new point
- Continue until all three points have been translated
- 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“.
