Money, Measurements and Mensuration :D

Units of mass, time, area and volume
Length: cm,m Mass: g,kg Time: am,pm(minutes,hours&seconds) Area: cm2 Volume: cm2 (by Jing Jie)

Duration of time interval
hours, minutes and seconds.(by Grace)

Four operations with money in decimal notation
money $3.30+$4.50=$7.80,$5.60-$1.10=$4.50,$5.10*4=$20.40,$6.60 divide by 3=$2.20 (by Harsh)

Four operations with length, mass, time and volume
Addition, Subtraction, Multiplication and Division (by Jing Jie)

Conversion of measurements from a smaller unit to a larger unit in decimal form, and vice versa
grams converted to kilograms must divide by 1000. kilograms convert to grams times 1000. (by Grace)

Perimeter of rectilinear figures
figures:length+length+breadth+breadth=perimeter (by Harsh)

Area and perimeter of a square, a rectangle and a triangle.
Square: Length x Breadth Rectangle: Length x Breadth Triangle: 1/2 x Length x Height (by Jing Jie)

Area and perimeter of a circle, a semicircle and a quarter circle.
circle is pie x radius x radius. semicircle=pie x 2x radius x 1/2. quadrant= pie x 2 x radius x 1/4 (by Grace)

Area and perimeter of a figure related to - square, rectangle and triangle
length*breadth=area for square and rectangle,
-length*base divide by 2 =area for triangle,
-length+length+breadth+breadth=perimeter for square
-length+length+length+perimeter for triangle (by Harsh)

Area and perimeter of a figure related to- square, rectangle, triangle, circle, semicircle and quarter circle.
-circle: radius*radius*pi=area,diameter*pi=circumference
-semicircle:radius*radius*pi divide by 2=area,diameter*pi divide by 2 + diameter=perimeter
-quater circle:radius*radius*pi divide by 4=area,diameter*pi divide by 4 + diameter=perimeter(by Harsh)

Finding
-one dimension of a rectangle given the other dimension and its area/perimeter
area ÷ other dimension OR (perimeter - other dimension2) ÷ 2 (by Grace)

- the length of one side of a square given its area/perimeter
square root area OR perimeter ÷ 4 (by Grace)

Volume of liquid
milli litre , litre (by Grace)

Volume of a solid made up of unit cubes
length of unit cube x breadth x height x no. of cubes. (by Grace)

Volume of a cube and a cuboid
length x breadth x height (by Grace)

Finding
-the length of one edge of a cube given its volume
cube root the volume (by Grace)

-one dimension of a cuboid given its volume and other dimensions
volume ÷ other dimensions (by Grace)

- the height of a cuboid given its volume and base area
volume ÷ base area (by Grace)

- the area of a face of a cuboid given its volume and one dimension.
volume ÷ one dimension (by Grace)

Part 2 : We could apply these skills and knowledge in real world applications such as counting money, measuring the length or width of an object(table). Besides that, it could also help us keep track of the time and weigh yourself to make sure that you are fit. (by: Jing Jie)

  1. Dear Team

    Thanks for sharing & elaborating the topics with the quick summary of content that you learnt in Primary school.

    Could you share, for example, how you could apply these knowledge and skills in real world applications. E.g. "How is the knowledge of the different types of units used to measure Volume of Liquid" being useful in real world application?

    Please look through again... You need not handle the sub-topics individually. Give a few examples to illustrate how you have applied the skills/knowledge would suffice :D

  3. Hi Jing Jie

    Thanks for the further elaboration.
    Could you get Grace to weave this input into the main write-up?

    :D
