  • Draw an array on the board with two rows of six dots. Facilitate a think-pair-share by instructing students to think about how they would describe the image on the board.
  • Have students talk to a partner and describe what they see. Then, call on students to share with the whole group. Listen for the vocabulary students use, and note whether they mention any of the tiered words you'll go over in this lesson.
  • Tell the class that you drew an array on the board, which is an arrangement of the dots in columns and rows. Point out the columns and the rows to provide a visual for students. Tell them that this is a visual representation of a multiplication problem (2 x 6).
  • Go over the student-friendly Language Objective and share that students will be exploring the similarities and differences between arrays during this lesson.
