Equal Groups and Arrays

Four plates with 3 cookies each: learners make and recognise equal groups, find totals by skip counting and repeated addition, and organise objects into arrays of rows and columns (up to 5 by 5). They write repeated-addition equations by rows and by columns and discover that both give the same total, the foundation for multiplication in Grade 3.

  • 3 lessons
  • About 55 minutes
  • Equal groups and arrays check: 8 questions
  • Ways to answer: fill in the blanks, choose an answer, count, match pairs, type a number and share out one each

  • Make and recognise equal groups and find the total by skip counting or repeated addition.
  • Describe an array with up to 5 rows and 5 columns and find the total, writing a repeated-addition equation.
  • Match arrays to equations by rows or by columns, explain why both give the same total, and solve array problems.
