Learning objects Arrays: word problems with products from 10 to 30

TLF ID L2054

Read a number problem and think about how to solve it. For example, when 13 is divided by a number, the answer is 6 with a remainder of 1. Write the problem as a multiplication or division number sentence with a missing number. Think about multiplication or division facts to find the missing number. Test your answer by making an array of equal rows and columns to show the multiplication or division fact and the remainder. This learning object is one in a series of five objects.



Educational details

Key learning objectives
  • Students apply knowledge of factors of numbers to solve problems with products up to 30.
  • Students apply the commutative property of multiplication.
Educational value
  • Students develop and consolidate knowledge of basic number facts that underlie effective multiplicative thinking.
  • Students interpret word problems to construct equations.
  • Provides opportunities to consider the relationship between multiplication and division.
  • Automated array construction provides a visual model to support understanding of the multiplicative relationship between factors and the additive nature of the remainder.
