Number Bonds to 50 and 100 Online Quiz

Here you will find a range of free printable math worksheets to help your child learn their number bonds to 50 or 100.

These sheets are carefully graded so that the easier sheets come first and give extra support.

Using these sheets will help your child to:

  • learn and practice their bonds to 50 or 100.

Want to test yourself to see how well you have understood this skill?.

  • Try our NEW quick quiz at the bottom of this page.

What is a number bond to 100?

We can look at number bonds to 100 as pairs of numbers with a total of 100.

However, knowing your number bonds to 100 is more than just being able to quickly recite pairs that have a total of 100.

We would also expect children to know all the facts related to the pair of numbers that have a total of 100.

In other words:

  • If we know that 63 + 37 = 100, we should also know
  • 37 + 63 = 100
  • 100 - 63 = 37
  • 100 - 37 = 63
  • And if we switch the equation on either side of the equals sign, we could add to this...
  • 100 = 63 + 37
  • 100 = 37 + 63
  • 37 = 100 - 63
  • 63 = 100 - 37

So there would be a total of 8 facts for every number bond fact that we would want children to be able to find!

The sheets below will help you child to learn their number bonds to 100 and accompanying facts!

Number Bonds to 100

videolesson.JPG

  • Number Bonds to 100 are pairs of numbers that add together to make 100.
  • To find the number bond that pairs with 28 to make 100, we think of the number that we add to 28 to make 100.
  • We can add 2 to 28 to make the next multiple of 10, which is 30.
  • Now from 30, we just add 70 to make 100.
  • In total we have added 70 + 2.
  • 28 and 72 are number bond pairs that add to make 100.

videolesson.JPG

  • In this number bond example, we are asked which number pairs with 64 to make 100.
  • First we add 6 to get to the next multiple of ten, which is 70.
  • From 70, we need to add 30 more to make 100.
  • Our number bond that pairs with 64 to make one hundred is 36.

Number bond is a mathematical concept used to help young children understand the relationships between numbers and their parts. It describes the relationship between a number and the combinations of smaller numbers that make it up.

For example , the number bond for 7 could be represented as 7 = 3 + 4, showing that 7 can be made up of the combination of 3 and 4. Number bonds are a visual representation that can help children understand basic addition and subtraction concepts and build a foundation for more advanced mathematical thinking.

Example 1: 8 + 4 = 12 Solution:  8 and 4 are the two numbers, and 12 is the third number that represents the sum of 8 and 4.

Example 2: 10 - 6 = 4 Solution:  10 and 6 are the two numbers, and 4 is the third number that represents the difference between 10 and 6.

Problem 3: 6 x 3 = 18 Solution:  6 and 3 are the two numbers, and 18 is the third number that represents the product of 6 and 3.

Number bonds up to 100 are pairs of numbers that add up to give the sum as 100.

For example, 25 and 75 are a number bond for 100, because 25 + 75 = 100.

Some other number bonds for 100 are:

i) 50 and 50 ii) 40 and 60 iii) 30 and 70 iv) 20 and 80 v) 10 and 90

Number bonds up to 1000 are pairs of numbers that add up to give the sum as 1000.

For example, 250 and 750 are a number bond for 1000, because 250 + 750 = 1000.

Some other number bonds for 1000 are:

i) 500 and 500 ii) 400 and 600 iii) 300 and 700 iv) 200 and 800 v) 100 and 900

Number bonds can help us with addition, subtraction and division.

Number bonds are relationships between numbers that show how they can be combined to make a whole. In addition, number bonds show how two or more numbers add up to a certain sum.

For example, a number bond for the number 7 would look like this:

i) 7 = 1 + 6 ii) 7 = 2 + 5 iii) 7 = 3 + 4 iv) 7 = 7 + 0

These number bonds show that 7 can be made up of different combinations of numbers, such as 1 and 6, 2 and 5, 3 and 4 or just 7 by itself. This concept is useful for helping young children understand addition and how numbers can be combined to make different sums.

Subtraction number bonds are pairs of numbers that when subtracted from each other, equals a certain number.

For example, the number bond of 10 is (10, 0), (11, 1), (12, 2), and so on.

i) 10 – 0 = 10 ii) 11 – 1 = 10 iii) 12 – 2 = 10 iv) 13 – 3 = 10

These number bonds help in understanding subtraction by breaking down the problem into smaller parts and finding the relationship between the numbers. Number bonds also help visualise subtraction and make it easier to perform mentally.

Number bonds in multiplication refer to the pairs of numbers that can be multiplied together to get a third number.

For example, if you multiply 2 and 3, you get 6. So, 2 and 3 are number bonds for 6. Generally, for any number n, the number bonds for n are all the pairs of numbers that can be multiplied to get n.

Here are some examples of number bonds for some common numbers:

i) 6: (1 x 6), (2 x 3) ii) 9: (1 x 9), (3 x 3) iii) 12: (1 x 12), (2 x 6), (3 x 4) iv) 16: (1 x 16), (2 x 8), (4 x 4)

Division number bonds are pairs of numbers that, when divided, equals a given number.

For example, if you have the number 8, the division number bonds would be:

i) 16 ÷ 2 = 8 ii) 24 ÷ 3 = 8 iii) 32 ÷ 4 = 8 iv) 64 ÷ 8 = 8

These division number bonds can be useful in helping students understand division as an inverse operation of multiplication, as well as helping with problem-solving and memorizing division facts.

Number bonds are a mathematical concept used to help young children understand the relationships between numbers and their parts. They describe the relationships between a number and the combinations of smaller numbers that make it up.

For example, the number bond for 7 could be represented as 7 = 3 + 4, showing that 7 can be made up of the combination of 3 and 4. Number bonds are a visual representation that can help children understand basic addition and subtraction concepts and build a foundation for more advanced mathematical thinking.

Subtraction number bonds are pairs of numbers that when subtracted from each other, equal a certain number.

Division number bonds are pairs of numbers that, when divided, equal a given number.

These division number bonds can be useful in helping students understand division as an inverse operation of multiplication, as well as helping with problem-solving and division facts memorization.
