#### Learning Objectives

Students will be able to apply logic and their knowledge of addition, subtraction, multiplication, and division to solve KenKen grid puzzles.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

#### Introduction

(3 minutes)
• 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.
