  • Ask students to brainstorm different types of puzzles they have worked with (e.g., jigsaw puzzles, tangrams, and word puzzles).
  • Tell students that today we are going to work with a type of grid puzzle called KenKen puzzles.
  • Explain to students that while working with puzzles is very fun, they are also a great way to practice our math skills such as logic, problem solving, addition, subtraction, multiplication, and division.

Beginning

  • Provide a student-friendly definition of the terms "puzzle," "grid puzzle," "logic," and "problem-solving" in students' home language (L1) and English (L2). Include a picture or the real object of the various puzzle types.

Intermediate

  • Tell students to talk to a sympathetic partner regarding their experience with puzzles before sharing out in the whole class brainstorm session.
