Introduction

(5 minutes)
Array PracticeWorking with Arrays
  • Give each student 25 counters.
  • Ask your students to make eight groups with three counters in each group.
  • Direct your students to count by threes.
  • Ask them to identify how many counters there are altogether.
  • Write an equation to show this. For example: 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3.
  • Tell students that today they are going to describe an array, or an ordered display, using number sentences.

Beginning

  • Provide students with eight cups and have them place three counters in each cup.
  • Provide students with the skip counting sequence of 3, 6, 9, 12, 15, 18, 21, 24.
  • Provide the definition of array in English and student's home language (L1).

Intermediate

  • Ask students to explain the definition of array to a partner, using their own words.
  • Have students complete a think-pair-share, defining the vocabulary word altogether.
