Lesson notes

Learning Objectives

Indicator: B7.1.2.3.1 - Illustrate with examples the meaning of repeated factors using counting objects such as bottle tops or bundle sticks.

By the end of the lesson, learners can:

Identify repeated factors in a multiplication expression such as 3 × 3 × 3 and state the value of each factor.
Build concrete models of repeated factors using bottle tops or bundle sticks to show the total value.
Explain that a power of a number is a shorthand way of writing repeated multiplication of the same factor.
Read and write powers using correct vocabulary, identifying the base and the exponent or index in expressions like 2⁵ and 3³.
Calculate the value of simple powers such as 3³ = 27 and 5² = 25 using concrete or symbolic methods.

Exemplars (from the NaCCA curriculum)

E.g.1: Model repeated factors using counters or bottle tops.
i. 3×3×3, is repeated factors, and each factor is 3.
E.g.2 Explain what is meant by a power of a number.
i. 2×2×2×2x2 = 2 5 =32
E.g.3 Explain the features of the power 2 3 The 2 in 2 3 is the base, while the 3 in 2 3 is the exponent or index
