When children start to explore and learn about patterns, it makes them build important foundations for later work on number operations. Algebraic patterns help children build a strong math foundation by creating, extending, naming, and talking.
Patterns are at the heart of math. The ability to recognize and create patterns helps children make predictions based on their observations; this is an important math skill. Understanding patterns help prepare children for learning complex number concepts and mathematical operations.
In this article, the need for algebraic thinking in grade 4 students and what kind of activities aid in developing this most required learning formulation could be seen.
To ensure students succeed at the formal study of algebra, algebraic thinking would be instrumental in improving their abilities.
Algebraic thinking includes
Perceiving and investigating patterns,
Studying and exhibiting relationships,
Evaluating how things change.
It is essential to understand algebraic symbols.
At the most earlier grades, little youngsters work with designs. Kids have a characteristic love of mathematics during this early age. Their interest is helps as they attempt to portray and expand examples of shapes, colors, sounds, and in the end, letters and numbers.
Furthermore, kids start to generalize examples that appear to be the equivalent or unique at a young age. This sort of classifying and summing up is a significant formative advance on the excursion towards algebraic thinking.
In the above video Arjun, a 3rd-grade Cuemath student, explains to us how he learned to count and recognize patterns at Cuemath.
Algebraic thinking for Grade 4: Patterns and Operations
Math Patterns are sequences that repeat based on a rule, and a rule is a set way to calculate or solve a problem. All through the initial assessments, patterns are an object of study as well as a mechanism too.
As students build up their comprehension of numbers, they can utilize patterns in varieties of spots or have a problem to perceive what 5 is or whether 6 is more significant than 8.
Looking at what is the same and what is different among functions lies at the heart of understanding algebraic skills and processes.
In grade 4, students investigate and learn addition, subtraction, multiplication, and division. They can search for designs that assist them with learning systems and realities.
They understand remainders and quotients in division. They utilize mental calculation and assessment techniques.
Students likewise find out about factors and multiples of numbers. They understand prime and composite.
Also, they learn and apply ideas that will help assemble an establishment critical for later work in Algebra. They identify patterns in generating outputs with rules. Such understanding will help them be successful with later algebraic functions and equations.
1. Comparing and ordering objects by weight
It allows students to apply their understanding of greater than and less than in a new context.
Finding the amount of an object that equals the weight of another by removing the same amount from both sides of a balance prepares them for later understanding algebraic expressions.
Find out the number of squares to be placed to balance the scale.
Here we use a balance to compare the quantities of two objects. As shown in the figure, one circle is equal to two squares, so what will be the weight of three circles.
6 squares are to be placed on the left side of the balance.
2. Finding factor pairs
Discovering factor sets permits students to develop their grasp of division as they find out about factors and divisibility rules. To find all the factor sets of a number, students should be asked to proceed in a figured out way by finding the factor pair of 1, then by 2, 3, 4, and so forth.
Write each multiplication fact and use Fraction rods to build each number and factor pairs shown.
Students finding out about factors find that a few numbers have less factors than different numbers. A prime number has precisely two factors: the number 1 and the number itself. A composite number has multiple factors. Since the number 1 has just itself as a factor, it is neither prime nor composite.
Use Color Tiles to model each number. Write the number. Is the number prime or composite?
Here the 3 × 3 grid is formed, so 9 is composite because 1, 3 and 9 are factors.
Here the 1 × 3 grid is formed, so 3 is prime because 1 and the number itself are the only factors.
4. Identifying Multiples and Division facts
A grasp of multiplication is helpful to students when they work with multiplication, division, and equivalent fractions. Additionally, they need to comprehend multiples to discover the least common multiples and most significant highest common factors. A considerable amount of time should be committed to building up youngsters' comprehension of multiplication and how it functions. Time invested in doing this is very much spent. Hence, kids become more sure with their understanding of multiplication before they proceed with their excursion into the multiplication table and tackling multiplication problems.
Answer the questions that describe the model.
How many groups are there?
How many balls are there in each group ?
Write a multiplication sentence to describe the model.
Multiplication fact = 2 × 10 = 20
How many balls are there altogether?
This can be written as
\(2 \times 10 \)
Which can be written as
\(2 × 10\)
Number of groups
Number of balls
No of balls per group
Use Color Tiles. Build the array. Answer the questions.
Is 18 a multiple of 6 ? Why or why not?
Yes, 18 is a multiple of 6 because there can be 6 rows of 3 or 3 rows of 6 as shown in the grid.
Multiplication fact = 6 × 3 = 3 × 6 = 18.
Solving a division problem is introduced as early as grade 2 by introducing division by distribution, division on the number line and writing multiplication and division statements.
and then they are introduced with long division and remainders. These concepts form the basis for generating the right division facts by students in grade 4. A few examples are given below for division by grouping and the division on the number line.
1. Fill the boxes
12 items are divided into 6 groups.
Each group has 2 items
Division fact: 12 ÷ 6 = 2
2. Divide using the number line.
Divide 12 into groups of 4.
Division fact: 12 ÷ 4 = 3
5. Extend patterns
Students should be able to express descriptions of patterns in words and in numbers. Students who understand a pattern will be able to extend the pattern.
Use Attribute Blocks to model each pattern. Describe the repeating part. How many times does it repeat?
Repeating part triangle, upside down triangle, circle
