Teaching Outlines

Definition, examaples
Order and radicand of a surd
Like Surds and Unlike Surds
Addition and Subtraction of Surds
Multiplication of Surds.
i.Multiplication of Surds having same Order
ii. Multiplication of Surds having different Order
Rationalising Factor of a Surd
Simplifying a surd by Rationalizing denominator of a surd

Concept 1: Definition of surds

Irrational root of rational number. Example: ${\sqrt {2}},7{\sqrt {5}},{\sqrt {x}}$

Learning objectives

know the meaning of surds
recognising radicand and order of surds

Notes for teachers

If you can't simplify a number to remove a square root (or cube root etc) then it is a surd. If it is a root and irrational, it is a surd. But not all roots are surds.

Activities

Concept-2: Like and Unlike surds

Learning objectives

Know the meaning of surd
recognising the meaning of order and radicand
Examples of like and unlike surds
To change surd to simplest form
Addition and Multiplication og surds

Notes for teachers

1.Like surds: A group of surds having same order and same radicand in their simplest form. Example: $3{\sqrt {5}},7{\sqrt {5}},x{\sqrt {5}}$
2.Unlike surds: Groups of surds having different orders or different radicandsor both in their simplest form. Example: ${\sqrt {a}},3{\sqrt {2}},x{\sqrt {5}}$
3.Addition and sustraction of surds. Example: $2{\sqrt {5}}+3{\sqrt {5}}-{\sqrt {5}}$
4.Multiplication of surds. Example: $7{\sqrt {3}}X2{\sqrt {5}}$

Activities

Activity for like and unlike surds click here

Concept-3: Addition of Surds

simplify the surds

$3{\sqrt {45}}+2{\sqrt {20}}-{\sqrt {5}}$

$=3{\sqrt {3X3X5}}+2{\sqrt {2X2X5}}-{\sqrt {5}}$

Assessment activities for CCE

Solving problems with same order and same radicand, same order and different radicand, different order and different radicand also different order and same order. Examples: Surds_CCE_Activity click here
