Mathematics: Geometry and Spatial Sense
- describe the relative locations and the movements of objects on a map
- draw simple maps of familiar settings, and describe the relative locations of objects on the maps
Geometry and Spatial Sense vocabulary and concepts
These lessons provide opportunities for teachers and students to gather evidence through teacher, peer, and self-assessments; and learning goals and success criteria. See Growing Success: Assessment, Evaluation, and Reporting in Ontario Schools, Chapter 4 for more information
This is the minds on button.
  • Review the prior knowledge.
  • Discuss mathematical vocabulary of location (e.g., beside, in front of, behind, to the right of, above).
  • Ask the class what they can share about an obstacle course. What is the purpose of an obstacle course? What kinds of obstacles might there be?
  • Explain that the students will be creating their own obstacle courses on Scratch Jr. in which the character they select will move from one location to another.
This is the action button.
  • Distribute the iPads and open up the Scratch Jr. app. Students may work in partners.
  • They will choose a character from the character library.
  • Provide the task list for students (e.g., the chosen character must complete the obstacle course; the obstacle course includes at least one physical obstacle; use three or more of the math vocabulary discussed to describe the movement of the chosen character).
  • The students are encouraged to look for incorrect or insufficient movements, then work to debug their program.
This is the consolidation button.
  • Brief gallery walk to allow students to view the work of their peers.
  • Guide a discussion regarding successes/challenges and what could be improved or added for next time.
Challenge students to include less or more tasks for the obstacle course (e.g., including more than one character, more than one obstacle, more than three movements and locations).
After completing Lesson 4 of the Scratch Jr. Animated Genres Curriculum, students can add backgrounds to their obstacle courses.
