Strand 3: Number
Strand 3 further develops the proficiency learners have gained through their study of strand 3 at junior cycle.
Learners continue to make meaning of the operations of addition, subtraction, multiplication and division of whole and rational numbers and extend this sense-making to complex numbers. They extend their work on proof and become more proficient at using algebraic notation and the laws of arithmetic and induction to show that something is always true.
They utilise a number of tools: a sophisticated understanding of proportionality, rules of logarithms, rules of indices and 2D representations of 3D solids to solve single and multi-step problems in numerous contexts.
As they engage with this strand and make connections across other strands, learners develop and reinforce their synthesis and problem-solving skills.
