Task 1
collaborative work
using TI-Nspire to
build 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
