Teacher Resources

Student computer usage for this lesson is: required

In the Lesson Resources folder:

  • Word Play
  • Word Play Rubric
  • Assessment

Lesson Plan

Getting Started (5 min)

  • Ask the students to work in small groups to create pseudocode for the following function:
  • Create a function titled 'is_palindrome' that inputs a word and determines whether that word is a palindrome.  If it is, return True, otherwise return False.
  • As a class, use the groups' pseudocode to create the function 'is_palindrome'.
  • Introduce the projects to students.  They will have a total of 2 sessions to complete their project. 

Independent Activity (40 min)

Students work individually on the Word Play and Assessment which are found in the lesson resource folder.

Wrap up (5 min)

Allow students to continue working to the end of class on their projects; have individual check-ins with students to make sure that they are on track and have a clear idea of what they need to complete the following day.
