Simple addition and subtraction worksheets
This worksheet is a great way to introduce your kids to simple addition and subtraction operations. It shows your kids pictures of objects that can be added or subtracted, such as candies, balloons, pencils, etc., and asks them to solve simple problems using these pictures.
For example, if they see two candies plus one candy, they write 2 + 1 = 3; if they see four balloons minus one balloon, they write 4 - 1 = 3; and so on.
This worksheet helps them understand the concepts of adding and subtracting using concrete objects.
Add or remove one from numbers up to 10
One of the simplest ways to add or subtract is to add or remove one from a number. For example, if we have 5 apples and want to add one more, we can simply put another apple next to the 5 apples and count them all. We get 6 apples! That means 5 + 1 = 6.
Similarly, if we have 6 apples and want to subtract one, we can simply take away one apple from the 6 apples and count the remaining ones. We get 5 apples! That means 6 - 1 = 5.
Adding or removing one is also called incrementing or decrementing a number. We can use this technique to change any number by one.
For example,
if we have 10 pencils and want to add one more, we can increase 10 by one and get 11 pencils.
If we have 11 pencils and want to subtract one, we can decrease 11 by one and get 10 pencils.
Complete the set or remove items to reach the corresponding numbers
Another way to add or subtract is to complete the set or remove items to reach the corresponding numbers. For example, if we have 3 cookies and we want to add 2 more, we can think of a set of 5 cookies and see how many more we need to complete it. We need 2 more cookies! That means 3 + 2 = 5.
Similarly, if we have 5 cookies and we want to subtract 2, we can think of a set of 3 cookies and see how many we need to remove to reach it. We need to remove 2 cookies! That means 5 - 2 = 3.
Completing the set or removing items is also called complementing or reducing a number. We can use this technique to change any number by another number. For example, if we have 7 balloons and want to add 3 more, we can complement 7 by 3 and get 10 balloons. If we have 10 balloons and we want to subtract 3, we can reduce 10 by 3 and get 7 balloons.
