In the 2nd-grade Math textbook program, students are introduced to and learn various lessons, and one of the important lessons is Terms - Sum. To help students reinforce their knowledge of this lesson, below, Mytour shares with you What is a term? Example exercises on terms in 2nd-grade Math. Parents as well as students are invited to follow along.
I. What is a term? What is a sum?
A term is an important component that makes up addition. In an addition operation, there need to be at least 2 terms. The sum is the result of adding numbers together, or the sum is the result of addition. Addition: a + b = c Where: a and b are addends; c and a+b are the sum. Example 1: 35 + 7 = 42 In this addition operation, we have: 35 and 7 are two addends. 42 and 35 + 7 are the sum. Example 2: 56 + 12 = 68 In the addition above, we have: 56 and 12 are two addends 68 and 56 + 12 are the sum
Addition: a + b = c
Where: a and b are addends; c and a+b are the sum.
Example 1: 35 + 7 = 42
In this addition operation, we have:
- 35 and 7 are two addends.
- 42 and 35 + 7 are the sum.
Example 2: 56 + 12 = 68
In the addition above, we have:
- 56 and 12 are two addends
- 68 and 56 + 12 are the sum
II. Example exercises on terms in 2nd-grade Math
1. Exercise stating addend and sum in each operation
Stating addend and sum in each operation is the most basic type of addend exercise in Grade 2 Math. In this exercise, you need to identify which part is the addend and which part is the sum from the given operation.
Example: State addend and sum in each operation below.
a, 36 plus 5 equals 41
b, 54 plus 12 equals 66
Solution:
a, 36 is the addend, 5 is the addend, 41 is the sum.
b, 54 is the addend, 12 is the addend, 66 is the sum.
2. Exercise on finding sum when addends are given
Finding the sum when addends are given is the next type of problem commonly encountered in examples of addends in Grade 2 Math. In this type of exercise, you need to calculate the sum of the addends provided in the problem and determine the sum required.
Example: Find the sum given the following addends:
a, 10 and 7
b, 23 and 15
Solution:
a, 10 + 7 = 17
b, 23 + 15 = 38
3. Practice Exercises on Summation
Summation exercises are also a type of exercise in 2nd-grade Math, where the task involves creating sums from given addends. For these exercises, the question may provide the addends and ask to create all sums with a specific result, or it may provide the addends and require creating sums and performing addition.
Example: From the numbers 4, 6, 7, 3, create all sums with a result of 10.
Solution:
We can create the following sums:
4 + 6 = 10; 6 + 4 = 10; 7 + 3 = 10; 3 + 7 = 10
4. Exercise type: Finding Unknown Addends
b, ... + 14 = 35
Solving the problem
a, 79 - 45 = 34, hence the number to fill in the three dots is 34.
b, 35 - 14 = 21, hence the number to fill in the three dots is 21.
Example 2: Find x, given 67 + x = 98.
Solving the problem:
x = 98 - 67
x = 31
Solution
5 + 3 + 4 equals 12 (trees)
Answer: The total number of ornamental trees sold by Nam's house in a day is 12 trees.
