In this article we are going to discuss about the mathematical concepts for fourth grade students. The students of fourth grade learn the different areas of mathematics, like place values of six digits numbers, expanded notations, place value chart, addition, subtraction, multiplication and division of three and four digits numbers, multiples and factors, HCF and LCM. Grade fourth students also learn unitary method, fractions, decimal numbers and measurement of time, length, mass and capacity.
Here we are going to discuss about some of them. This article will be helpful in solving fourth grade math home work.
Topics of Solving Fourth Grade Math
Some of fourth grade mathematical topics are as follows:
Place value: To read and write large number easily, the Indian place value chart is divided into periods as shown below:
Practice Questions:
(1)Write the number name of these numbers:
(a) 2, 50,946 = Two Lakh fifty thousand nine hundred forty six.
(b) 6, 92,438 = Six lakh ninety two thousand four hundred thirty eight.
(c) 20, 10,101 = Twenty lakh ten thousand one hundred one.
(1) Write the numeral of these number names:
(a) One lakh fifty thousand two hundred eighteen = 1,50,218
(b) Nine lakh ninety five thousand sixty three = 9,95,063
(c) Seventeen lakh fifteen = 17,00,015
Simplification involving four fundamental operations:
In this lesson we will learn to use all the operations together. The fourth grade learners are able to learn the order of operations through this section.
Step 1 ---- Of
Step 2------Division
Step 3 ------ Multiplication
Step 4 ------ Addition
Step 5 ------ Subtraction
So the order of operation is ODMAS.Now we will do some simplification using ODMAS rule:
Practice Questions:
(a) Simplify 36÷ 6 x 4 + 2 – 8
= 6x 4 + 2 – 8
= 24 +2 – 8
= 26 – 8 =18 Ans.
(b) Simplify 6 + 8 ÷2 -2 x 1 + 5 of 2÷ 5
= 6 + 8 ÷ 2 – 2 x1 + 10 ÷5
= 6 + 4 – 2 + 2
= 12 - 2 = 10 Ans.
Now simplify these questions:
(a) 23741 - 3826 ÷ 2 x 6 + 221
(b) 529 x 71 – 630 of 6 ÷ 3 + 4
(c) 6000 +9000 ÷ 500 of 6 – 2000
(d) 6699 ÷ 33 +3075 ÷ 25 – 203
Answers: (a) 12484 (b) 36303 (c) 4003 (d) 123
Solving Fourth Grade Math Homework-unitary Method
Some basic knowledge is very important for fourth grade learners like:
- We have to add when we find the total cost of things tat we purchase.
- We have to subtract when we take back the balance.
- We have to multiply to calculate the cost of more articles.
- We have to divide when we find the cost of one.
Practice Question:
If the cost of 25 Milton jugs is Rs. 8,250. What is the cost of 48 such Milton jugs?
Solution: The cost of 25 Milton jugs = Rs.8, 250
The cost of 1 Milton jug is Rs.8, 250 ÷ 25 = Rs.330
The cost of 48 Milton jugs = Rs. 330 x 48 = Rs.15840
Solve these problems:
28 digital diaries cost Rs.70, 560. What is the cost of 15 such diaries?
Answer: 37,800
