Introduction

Use these assembled OER to see if you can master the CXC CSEC Specific Objectives for Number Theory

Specific Objectives:
01 | 02 | 03 | 04 | 05 | 06 | 07 | 08 | 09 | 10

Specific Objective 1

The CSEC Mathematics, Number Theory curriculum has a specific objective (#1) that students should be able to…

‘distinguish among sets of numbers; Set of numbers: natural numbers {1, 2, 3, …}, whole numbers {0, 1, 2, 3, …}, integers {…-2, -1, 0, 1, 2, …}, rational numbers (qp:p and q are integers, q ≠ 0), irrational numbers (numbers that cannot be expressed as terminating or recurring decimals, for example, numbers such as π and √2), the real numbers (the union of rational and irrational numbers); sequences of numbers that have a recognisable pattern; factors and multiples; square numbers; even numbers; odd numbers; prime numbers; composite numbers’.

In this module we have compiled a number of Open Education Resources (OER) to help you achieve this objective.

1. CK-12 – Classify and order real numbers
2. Open High School – Find factor pairs of given numbers
3. OpenAlgebra – Real numbers and the number line
4. CK-12 – Subsets of real numbers
5. Open High School – Classifying real numbers

‘order a set of real numbers’.

In this module we have compiled a number of Open Education Resources (OER) to help you achieve this objective.

1. CK-12 – Classify and order real numbers
2. Open High School – Compare decimals
3. Open High School – Order decimals
4. Open High School – Order decimals from least to greatest

Specific Objective 3

The CSEC Mathematics, Number Theory curriculum has a specific objective (#3) that students should be able to…

‘generate a term of a sequence given a rule; Sequences of numbers that have a recognisable pattern’.

In this module we have compiled a number of Open Education Resources (OER) to help you achieve this objective.

1. Everything Maths – Number patterns
2. OpenStax – Number patterns
3. millaismath12 on YouTube – Generate a sequence given a rule
