Measurement Games for 4th Graders

SplashLearn education games for Grade-4 propel kids thinking and reasoning to an advanced level. With the knowledge of measurable quantities and units, it is easy to comprehend the relationship of the units. Using the attributes like length (width, breadth) and height, the concept of geometrical figures (regular and non-regular shapes) is introduced. To draw the geometric figures correctly, angle measurement techniques also instigated.

Understanding the advanced concepts:

To standardize the globally acknowledged measurement units for cognizance, the relationship between the units is established. Converting units for standard measurement procedures in later grades require a strong conceptual knowledge of such relationships.

For example, which quantity is larger? 20 centimeters or 20 kilometers. As the grade-3 worksheets insist on estimation and selection of appropriate quantities, kids can easily learn to deduce and interpret the proportionate relationships between the quantities.

Measuring and creating accurate angles (using suitable geometrical instruments in the classroom) is always an easy task for a kid regularly practicing SplashLearn worksheets. Adhering strictly to the common core math standards, learning advanced concepts is absolute fun with interactive theme-based educational games.

Learning & outcome

Application of knowledge about different units of measurement is the next level to enhance the logical reasoning and thinking capabilities of kids. With real-life examples from the surroundings, kids can easily use their math skills to select the suitable units for the measurement. Also, the basics of angle measurement formed between two lines and creating angles as per given values lay a firm base for learning geometrical math and solving trigonometry word problems in later grades.

The expected outcomes of the learning are:

• Associating metric and customary units to correctly measure a physical quantity
• Evaluating the area and the perimeter of simple and complex figures
• Understanding the technique to measure the angle formed between two lines and creating the “angle” as per the given degree
• Using the “angle” measurement basics to add and subtract angles

Next section outlines the essential math skills to achieve the learning goals.

Required math skills

A Clear understanding of different units of measurement is the prime skill required to establish the relationship between the metric or customary units. At the same time, the basics of area and perimeter from grade-3 worksheets are instrumental in computing the two quantities for the simple and complex figures. To learn about the angle measurement, kids are expected to be familiar with the counting up-to 3-digit numbers and using basic math skills (addition, subtraction, multiplication, and division) with them.

Engagement

Measurement is one of the most important aspects of learning applied mathematics. Grade-4 SplashLearn worksheets institute the understanding of such advanced concepts without any difficulty. Fun learning games and worksheets offer unique word-problems and puzzles related to different measurement units. With a theme-based interactive interface to motivate and promote healthy engagement, kids learn to create angles and solve riddles within no time. Comprehensive curriculum assists the kids for accelerated learning and to excel in math.

• Relationship between measurement units

To measure the food portions (solid and liquid) as well as human body weight and other objects, suitable measurement units are chosen. The standard interpretation of these units globally makes it easy to trade the commodities. The closest scalable figure (having the least numeric value) is chosen to mention the portion.

For example, instead of writing 20,000 milliliters or 2000 centiliters, the measure will be written as 20 liters. Another example is the dosage for a syrup. Instead of writing 0.01 liter, the physician will write 10 milliliters for clearer understanding.

The denomination charts of the metric and U.S. customary units are described as follows:

Application

Measurement units and the interrelationships between them are highly useful in almost all the fields of mathematics and pure sciences. These fields are physics, chemistry, biology, geography and medical sciences. Using the proportionate measurements, clinical research with sensitive elements and chemicals is performed in the laboratory.

Knowledge of length along with angle measurement and similar physical quantities is applied before the construction of columns (in architectural science) to lay a strong foundation underneath. The firmness of the pillars is responsible to withstand the weight imparted on a floor within a building.

Construction of ships, cars and other vehicles is also based on the mathematics of physical quantities and associated geometry.

Terms to remember

• Metric units (length, weight, and volume)
• US customary units (length, weight, and volume)
• Area and perimeter

As the kids become familiar with the measurement units, their interrelationships and advanced math skills associated with area and perimeter; different skills are instigated to boost “quick math” skills in the kids. Measurement educational games and worksheets for grade-3 hone the thinking and reasoning of the kids to understand the area and the perimeter.

As the multiplication of two numbers (single-digit and double-digit) is also a part of the grade-4 curriculum; kids learn to calculate the area of geometric figures (square and rectangle) by multiplying the length of the sides.

The computation of area and perimeter is done with following formulae:

Understanding complex figures

Using the above formulae, area and perimeter of complex figures can be calculated by portioning them into smaller squares and rectangles.

For example, in the following figure; red dash-line divides the complex figure into 3 geometric figures (rectangles). To evaluate the perimeter and the area, use the above formulae to quickly obtain the result.

Reference image: Length of sides (3 and 4 units) can be calculated by the visual observation as well as by the addition and subtraction of lengths mentioned in the figure.

Easily calculate the area for following three rectangles:

• 2 x 5 = 10 units
• 5 x 3 = 15 units
• 4 x 5 = 20 units

• Total area is : 10 + 15 + 20
• 45 units

Application

Area and perimeter of geometric figures are a math essential with significant utility in several fields. The concept is employed in designing of furniture items like tables, chairs, beds, and others. It is also used to evaluate the land area, carpet area and other quantities in farming and architectural construction for tasks like fencing, tiling, polishing, and others.

Various statistical tests like Chi-square, correlation, and regression are applied on the area of the fields to find out the fertility of land & predict the crop production feasibility.

Terms to remember

• Length
• Breadth

Angle measurement

The elementary knowledge of geometric shapes covers the measurement of the physical quantities such as length and breadth. But, the space between the two adjacent lines is not a linear quantity. To measure this specific distance, a new unit evolved which is known as radian or the degree in modern mathematics.

Several Greek & Babylonian astronomers and mathematicians such as Timocharis & Archimedes defined this radial distance by dividing the circle into 60 equal parts, known as 60 arc minutes. Later, the circle was divided into 360 equal parts and defined the each unit distance as “1 degree”.

Next section elaborates the different angles formed by equally dividing the circle into 4 equal quadrants and constructing them using geometrical instruments.

How to create angles

To create an angle of a certain degree, two lines are drawn. The first line is a straight base line (from the center to the number 0) as marked on the protractor. For the other line, the respective degree is marked first on the outer of the protractor. This point is  joined to the beginning point of the first line to create the required angle.

Reference images: Standard protractors used to measure and draw angles

Another instrument to draw accurate angles are the geometric compasses. In such compass, a pencil can be attached to draw a circle and angles of various degrees.

Next section details the concept of addition and subtraction of angles for analysis.

Add and subtract angles

Two consecutive angles on a plane can be added or subtracted to form a new angle. The resulting angle will always measure from 0 to 360 degrees. Math learning games on angle measurement from SplashLearn comprise of multiple worksheets and math riddles to practice and improve the geometrical skills.

Application

Angle measurement and creating are the fundamental skills to draw different geometric figures. The knowledge of angles and their core concepts in essentials in understanding the basics of trigonometric functions and analogies.

Real-time application of angle measurement is in the construction of architectural buildings. It is highly useful in drawing accurate maps for surface, air and marine navigation. Different instruments like a protractor, compass, divider, and others are used by navigational engineers and architects to prepare a primal functional print of the final product.

It is also the foundation of geographical sciences as the unit “degree” is used to measure the latitude and longitude of the places. The entire world is divided into 24 different time zones with a longitude of 15 degrees.

Instruments to use
