**Task 1**

**collaborative work**

using

*TI-Nspire*tobuild your foundation on the key concept using examples presented in a collaborative environment.

========================================================

**Task 2**

**Pair work**

based on the activity in task 1, reflect on the processes involved and write it down on your worksheet 5.

Identify at

*least 2 points*for consideration for 'Change of Subject'.You may discuss with a partner in class.

Submit this at the end of the lesson.

reference:

Worksheet 5, ACE learning.

========================================================

**Task 3**

**individual work**

**Extension of understanding on Change of Subject**

Identify a formula in other subject areas (other than Mathematics)

- define which subject area the formula is applied and what the formula is about

- define all the variables used

- identify a variable (other than the one presented) to make a subject.

(ensure that this is possible)

[post this as a comment - do not include your solution[

*example:*

Subject: Physics

This formula is about the motion (movement) of an object

v = u + as

v - final velocity

u - initial velocity

a - acceleration of object

s - displacement

Question:

Make a the subject of the formula.

Arithmetics Error - division

ReplyDeletetransfer error - plus/minus sign

Task 2

ReplyDeletetransfer error - positive/negative indication

arithmetics error - division of the incorrect terms

1) Try to avoid arithmetic errors such as failing to multiply or divide correctly, resulting in deriving the wrong answer.

ReplyDelete2) When carrying signs (+,- etc.) to the other side of the equals to sign, change the symbols

Done with Ada.

Subject: Physics and Astronomy

ReplyDeleteThis formula is about the amount of energy is the amount of mass a body has.

E = mc^2

E - Energy

m - Mass

c - Speed of light

Question:

c=√E/m

1) There is an error about the misconception that x+4=q (q) is actually q+4=x.

ReplyDelete2) The second error is actually an error about dividing error of incorrect terms

Arithmetic error-division

ReplyDeleteTransfer error-forgot to change the sign when transferring to the other side.

(Done with Kang Xiong)

E=mc^2

E=energy

m=mass

c=speed of light

Task 2:

ReplyDeleteArithmetic error division of the wrong terms

Transfer error: plus/minus sign is confused

Task 3

Geography

R/r

R=Rise

r=run

Task 2 (Sylvia)

ReplyDeleteTransfering error - negative and positive places

Task 2

ReplyDeleteArithmetic errors like the incorrect division and the wrong results from a certain equation as well as errors such as transferring of wrong signs as well as positive and negative signs.

Done with Desiree

Task 2

ReplyDeleteEsther Tiey:

Transfer error - plus/minus sign

Suppose to divide but multiples.

Task 3

ReplyDeletePhysics

Distance = Speed x time

Fine Speed

Task 2

ReplyDeleteWhen dividing, make sure that you also divide the other side of the statement.

When transferring subjects, make sure that you change the signs.

Transfer errors. (-) Negative and (+) Positive.

ReplyDeleteArithmetics Error. Division, Multiplication, etc.

Errors:

ReplyDeleteTransferal Error: For example: x=3b+4

x+3b=4 (When the person transferred 3 over, he forgot to switch the sign to minus.)

Arithmetic Error: Some people are just careless and does some of the operations wrongly.

Task 2

ReplyDeleteTransfer errors. (-) Negative and (+) Positive.

Arithmetics Error. Division, Multiplication, etc.

Done with Daniel.

Task 2

ReplyDeleteDone with Jasmine

1) Miscopied

2) Left out alphabets

3) Forgot to multiply/divide

4) Wrong usage of signs

5) Moving mistake, instead of +/- becomes the other way around

Adil, Mateen, Kenneth

ReplyDelete2 Considerations/Errors:

1. Arithmetic error, eg. Forgot to divide both sides by the same value

2. Transfer error, eg. + was not converted to - when changed sides

Task 3

ReplyDeleteDistance = Speed x Time

Make Time the subject

Task 3

ReplyDeleteChemistry:

CO+O₂=CO₃

Make O₂ the subject

Boon Pin & Boon Pin Task 2:

ReplyDeleteCrossover:

1) + ➔ -

2) - ➔ +

3) × ➔ ÷

4) ÷ ➔ ×

Remember to factorize and group like terms, it helps

Physics

ReplyDeleteG = mgh

G - Gravitational Potential Energy

m - mass

g - gravitational field strength

h - height

Make the subject the height.

Task 3:

ReplyDeleteGravity: mgh

mass × gravity force × height

High Score + Mr Johari = Starbucks for free =)

Task 3:

ReplyDeletePhysics:

KE=(1/2)(m)(v^2)

KE=Kinetic Energy

m= mass

v=velocity

Find the velocity

Phsyics:

ReplyDeleteMoment

FxPerpendicular Distance = M

Task 3:

ReplyDeleteEnergy

KE=(1/2)mv^2

make v the subject

Speed of an object is Distance/time

ReplyDeletemaking speed as the subject

Speed = Distance / Time

ReplyDeleteMake time the subject.

Physics

ReplyDeleteG = MGH

Mass x gravity force x height

Make mass the subject

Distance = speed x time

ReplyDeletemake time the subject
