Conditions and Branching

Fourth graders use IF, ELSE IF and ELSE to choose between many paths, learn that the first true condition wins (so order matters), trace nested decisions, and test every branch, including the boundaries between branches.

  • 4 lessons
  • About 85 minutes
  • Branching check: 8 questions
  • Ways to answer: choose an answer, trace code, highlight a text, match pairs, type a number and sort into groups

What learners will discover

  • Use IF, ELSE IF and ELSE to choose between more than two paths, checking conditions from the top.
  • Put conditions in the right order so that ranges work, because the first true condition wins.
  • Trace nested decisions: an IF inside another IF.
  • Test every branch of a program, including the boundaries between branches.
