Measurement Games for 3rd Graders

Grade-3 measurement games for SplashLearn unleash the kid’s computation skills and visual observation of geometrical shapes. Previous grades develop a clear understanding of length measurement and units. Now, the measurement of other physical quantities like weight and capacity is introduced. With customary and metric units, kids learn to weigh the solids and liquids. Also, reading and recording time helps the kids to easily tell the time and solve the time-based problems.

What is “measurement”?

Definition of measurement at this level is classified as per the quantity. “Measurement” in the practical aspect refers to the defined magnitude of a quantity or figure in globally accepted standard units. It evaluates the size (distance, height or length) and weight/mass and volume/capacity for analysis.

Other measurable quantities are time, area and perimeter. Each quantity has different instruments to measure in standard units.

Types of measurement

Learning & outcome

The comprehensive knowledge of measurement is an absolute math essential. With the cognizance of physical quantities (such as length, height, weight, volume and others), the measurement units allow the kids to understand their practical aspect. 

SplashLearn educational games for the grade-3 aim of enhancing knowledge about other measurable attributes of the geometric figures (regular and irregular).

The learning games anticipate the following outcomes:

• Estimating and selecting the correct customary and metric unit to measure physical quantities (length, height, weight and capacity/volume)
• Measuring general objects (solids & liquids) using suitable instruments and units
• Understanding the concept of reading and recording the current time and intervals
• Representing the data on a bar graph and line plot for interactive graphical representation and solving word problems
• Calculating the area and perimeter of the geometric figures by visual observation, counting, and graphical interpretation

Required math skills

Formal counting and understanding of day intervals as the morning, afternoon, evening and night are helpful in learning the utility of a clock. With these skills, kids can interpret the relevant time by reading an analog clock. As the kids learn about length estimation and measurement and conservation of a measure; learning about weight and volume is easier. Other basic math skills like addition, subtraction, division, and multiplication are a mandate to calculate the area and the perimeter of the geometric figures.

Engagement

SplashLearn content strictly adhered to the curriculum of common core math standards to align the learning with school. Calculation of elapsed time, reading and recording time are other skills which are instrumental in learning time measurement. With the knowledge of different units to measure weight, capacity and time; kids start establishing relationships between day-to-day math problems.

Calculation of area and the perimeter hones the organizing skills in kids to arrange their books, clothes and other objects on the table or in the cupboard. SplashLearn educational games are acclaimed for their learning-oriented and interactive interface to engage a child. With significant improvement in the math skills and building of reasoning skills by solving math puzzles; worksheets help the kids to excel in math.

Time measurement

Time measurement is used for evaluating the time interval or the duration required to perform a task. Contemporary time measurement devices are wall-clocks, wrist-watch, stopwatch, and calendar.

Each analog clock has 12 equal divisions. Each division has 5 minutes. A usual analog clock has 3 hands. These hands are second, minute and hour hand. The hour hand is smaller than a minute hand. Whereas, the second hand is a relatively thinnest hand on a clock. Also, it has a continuous motion.

        

Reference images: An analog clock with hour, minute and second hand. Regular 12 hour analog clock. The markings outside the circle denote the minutes for each division. Inner markings denote the hour.

 

Reference image: 24-hour analog clock. The numbers from 1 to 24 denote the hours. Numbers on the inner circle denote the corresponding minutes covered. Minutes reset to 0 at the 12th-hour count.

The other time-measurement instrument is a calendar. The English calendar has 12 months from January to December. These months have approximately 52 weeks in total, classified from Sunday to Monday. SplashLearn fun games on time measurement are curated for curious kids resulting in an active and alert mind.

Units of measurement

Standard time measurement units are:

Reference image – Time measurement units

• Second
• Minute (has a definite magnitude of 60 seconds in 1 minute)
• Hour (has a definite magnitude of 60 minutes to complete 1 hour)
• Day (has 24 hours)
• Week (has 7 days)
• Gregorian month and year (commonly used 12-month calendar)

How to read and record time?

The three hands on an analog clock complete the rotations in the defined magnitude to display the correct time. Starting from number 12, the following is the rotation cycle:

• The second-hand moves from right to left till number 6 and left to right till number 12 to complete a minute. 60 divisions, each of 1 second complete 1 minute
• With each rotation of “second” hand, “minute” hand moves further by 1 minute
• A “minute” hand moves from right to left till number 6 and left to right till number 12 to complete 1 hour
• To calculate the number of minutes elapsed for the respective hour, multiply the number pointed by the “minute” hand to 5
• With each rotation of “minute” hand, “hour” hand moves from one number to the proceeding number

To record a time, check the numbers pointed by each hand.

For example, if hour hand points to number 2 and minute hand points to number 3, then the time will be calculated by multiplying the number 3 to 5. It will be written as:

• 2 hours, 15 minutes or a quarter past 2.

If the “hour&rrdquo; hand is pointing to the number “4” and the “minute” hand is pointing to the number “6”, then the time will be written as:

• 4 hours, 30 minutes or half past 4

If the “hour” hand is pointing to the number “6” and the “minute” hand is pointing to the number “9”, then the time will be written as:

• 6 hours, 45 minutes or quarter to 6

If the “hour” hand is pointing to the number “8” and the “minute” hand is pointing to the number “12”, then the time will be written as:

• 8 o’clock

Application

Time recording and measurement is useful in day-to-day events. The overall routine of the day is scheduled by suitably dividing the time slots.

In the events like sports activities, matches, athletics and similar events, recording of the time is an essential as per the rules.  

Instruments to use

• Analog clock
• Wrist watches
• Stopwatch

Terms to remember

 

• There are 2 systems of reading & recording time as follows:
• 12-hour format – the system is commonly used in households and offices to read and record time
• The clock cycle starts at 12 midnight and runs through noon
• Read as AM (After meridian, covers the night and morning hours)
• The hour count starts from 0 to 12
• Clock cycle continues again until midnight 12 to complete a day
• Read as PM (Post meridian, covers afternoon and evening hours)
• The hour count starts from 00 hours and continues till 2400 hours
• 24-hour format – the system is widely used for navigation, military time reading and scientific purpose to prevent any confusion
• The clock cycle continues for the complete 24 hours to mark a day
• The time is read and recorded in 4 numbers, for example, 02:00 PM will be written as 1400 hours. After 12:00 noon, time appends to 13 instead of 1.

Weight & Capacity

• Weight/mass measurement – The amount evaluated to weigh an object which is solid in shape. It determines how heavy the object is?
• Volume/capacity measurement – The space an object (in liquid form) takes up is the volume. For a hollow object, the volume is the amount of liquid that object can hold.

Thus, the measurement units for the weights of solids and volume are different.

Application

Weight and volume measurement are widely used to portion the food items. Different weighing scales are used to weigh human body weight for the general and medical purpose. Measurement of food items as per recipe directions is applied in the preparation of gourmet foods.

Volume measurement is used to measure liquids such as juices, syrup, oil, water, and gasoline. With defined capacity, the suitable volume is filled in the containers to hold the liquid. For example, a full carafe measures 750 ml or 25.3 U.S. fluid ounces. A lemonade drink requires one glass of water or 250 milliliters of water.

Weight and volume measurement are highly useful in maths and applied sciences. The instruments for measurement are used in laboratories to conduct tests and scientific research as well. Also, the simple weighing scale (generally with a weight limit up-to 5 kilograms) is used to weight postal mail and luggage for courier purpose.

Terms to remember

• Metric units
• US customary units

Data representation?

To comprehend a large set of data for easy interpretation, graphical presentation methods such as the bar graphs and line plots are used.

Different bars (vertical or horizontal) corresponding to figures and different categories are drawn to compare the data in bar graphs. For line plots, values are marked against a number line with equal divisions. These values are referred as frequency. Division on the line plot can change depending on the range of data.

Some examples where bar graph or line plot is used are as follows:

• Representation of height in centimeters for 5 tallest students in the classes (bar graph)
• Number of coins 3 kids carry to the supermarket (line plot)

Application:

As data representation on bar and line are graphical techniques for representing data, interpretation is relatively easy. The graphical representation is also helpful in deducing a mathematical relationship or hypothesis between two or more quantities. These quantities are either fixed or variable in nature and may cross each other.

In later grades, word problems to find break-even points or the correlation of two quantities is used to learn statistical methods easily.

Instruments to use

• Ruler
• Graph paper

Terms to remember

• Number line
• Frequency

Area & perimeter

The objects around can be measured using physical quantities like length, height, weight or volume (for liquids). Another measurable quantity of 2-dimensional or 3-dimensional objects is the “area” of that object.

It is defined as the number of unit squares contained in an object. The units of measurement are standard units of measurement (metric and US customary). As it’s a square, the unit used will be prefixed to it. For example, square meter, a square inch or square feet.

        

Reference image: Surface area and the perimeter

Another measurable attribute of 2-dimensional objects is the perimeter. It is the sum of the sides for the given polygon measured in the standard units.

Application

The two quantities are highly useful. Efficient placement of objects can be done by calculating the area. The objects can be a table, carpet, cupboard or a cot.

The perimeter is useful to calculate the periphery of fields by farmers. It is also applied in calculating the construction material required to fence a field or a park.

Reference image: In the above figure, the area is 10 square centimeters. The perimeter is the sum of the sides which is 10 cm (5+5+2+2 cm)

Reference image: Area can also be calculated for polygons like square and rectangle by multiplying the sides

Finding missing sides:

In complex word problems, kids can easily find the missing length of any side by visual observation. For different polygons like triangles, square, rectangle and quadrilaterals of equal length sides (pentagon, hexagon, septagon, octagon, nonagon or decagon; missing length can be calculated if quantities like area and perimeter are given. Basic math skills like multiplication, division and progressive addition are essential to evaluate the missing length.
