3rd Grade Math

Free 3rd grade math problems cover all the topics that students learn in class and give students the opportunity to practice every day. Various topics of 3rd grade math constitute an important part of the mathematical curriculum. The perimeter, area of figures have focused on formulas. The concept of equality is to be understand by showing equivalence relations between two expressions using Commutative and associative properties. Where as probability predicts the theoretical probability of an event and tests the prediction through experiments.
Third grade students will be able to fulfill objectives like:

Adding equals to both sides of an equation

Example:

453 + (543 + 345) = ____ + (453 + 345)

Solution:
453 + (543 + 345) = 543 + (453 + 345)

Evaluating expressions with operations addition, subtraction and multiplication

Example:

15 + (25 - 5) $\times$ 6 = _____

Solution:
15 + (25 - 5) $\times$ 6 = 15 + 5 $\times$ 6

= 15 + 30

= 45

Using variables and evaluating expressions using variables

Example:

What is the value of x - 2 = ___ , when x = 5.

Solution:

x - 2 = ___ , when x = 5

=> 5 - 2 = 3

Area of Rectangle

Example:

Find the area of rectangle with length of 5 m and width 7m.

Solution:
Length of the rectangle = 5
Width of the rectangle = 7

Area of rectangle = length $\times$ width

=> Area of rectangle = 5 $\times$ 7 = 35 square m

Solved Examples

Question 1: Convert the measuring units as indicated

2 hour = _____ min
Solution:

In 1 hour = 60 min

=> 2 hour = 2 $\times$ 60 min

=> 2 hour = 120 min, is the answer

Question 2: Find the missing addend.

125 + ____ = 200

Solution:

Let missing addend be x

125 + x = 200

=> x = 200 - 125

=> x = 75

=> 125 + 75 = 200 (Which is true)

Question 3: Find the perimeter of rectangle with length 4 ft and width 2 ft.
Solution:

Length of the rectangle = 4

Width of the rectangle = 2

Perimeter of rectangle = 2(Length + Width)

=> Perimeter of rectangle = 2(4 + 2)

=> Perimeter of rectangle = 2 $\times$ 6 = 12

Hence, Perimeter of rectangle is 12 ft.

Question 4: Find the probability of getting tail while tossing a coin.

Solution:

Sample Space = {H, T}

Number of possible outcomes = 2

Number of favorable outcomes = 1

=> Probability of getting tail = $\frac{Number of favorable outcomes}{Total number of possible outcomes}$

= $\frac{1}{2}$

=> Probability of getting tail is $\frac{1}{2}$.
