## Where to Find Printable Reading Worksheets

Teaching children to read is an important skill they’ll use for the rest of their lives. When children need extra practice using their reading skills, it helps to have worksheets available. You can find an assortment of printable reading worksheets for free and for sale on several websites.

## Teacher Websites

There are several teacher websites where you can download reading comprehension worksheets they created for their classrooms. One advantage of using these worksheets is that they are designed for specific reading levels and have been tested in a classroom. Many follow the formats used on state and local tests that measure reading ability. The teachers sometimes include anecdotal notes and tips for making the worksheets more effective.

## Publisher Websites

Publishers of textbooks, education research and professional development books sometimes offer worksheets on their websites. These worksheets usually are samples from the books they publish so that you can preview the content. Book publishers sometimes produce worksheets to pair with their books. If you’re looking for additional practice while reading a specific book, check out their websites for graphic organizers and comprehension questions.

You also can purchase collections of traditional and homeschool worksheets in digital books arranged by reading level. Many of these collections are themed by genre or subject matter. This makes it easy to select worksheets that match the child’s interest or to build background knowledge in specific areas.

## Teacher Resource Sites

Whether you’re a teacher or a parent, teacher resource websites are another option for finding reading worksheets. Some sites like Teachers Pay Teachers let teachers upload worksheets they’ve created and offer them for sale. Others are more collaborative and give teachers a place to share best practices and materials with others. If you’re looking for materials to use in a homeschool setting or for after-school practice, check out these sites. In addition to the worksheets, you get access to a community of educators who can help you find the right materials for your children.

## Literacy Programs

Even for-profit literacy programs offer free worksheets for parents and teachers. Although they’re usually designed for use with the company’s program, you can use them for other lessons. For example, the company Reading Horizons has downloadable phonics worksheets that work with its digital phonics program and face-to-face lessons. English learner sites are other good sources. Because these programs are geared toward children learning the English language, they incorporate social studies and science lessons along with the reading skills.

## Nonprofit Literacy Groups

Organizations like ReadWorks and edHelper have reading comprehension worksheets available on their websites. You can find reading passages with question sets and vocabulary support to help children practice and improve their reading skills. On the ReadWorks website, you can search for worksheets by grade level, text type and topic. This makes it easy to find worksheets that meet the child’s specific needs.

In order to access this I need to be confident with:

This topic is relevant for:

Here we will learn about different types of sequences including arithmetic sequences, geometric sequences and quadratic sequences and how to generate them and find missing terms, along with special sequences like the fibonacci sequence. We will also learn how to find the nth term of linear sequence and the nth term of a geometric sequence and how to work out whether a particular number appears in a sequence.

There are also sequences worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.

## What is a sequence?

A number sequence is a set of numbers that follow a particular pattern or rule to get from term to term.

There are four main types of different sequences you need to know, they are arithmetic sequences , geometric sequences , quadratic sequences and special sequences.

1 Arithmetic sequences

An arithmetic sequence is an ordered set of numbers that have a common difference between each term.

If we add or subtract by the same number each time to make the sequence, it is an arithmetic sequence .

Step-by-step guide: Arithmetic Sequence

## Arithmetic sequences examples

Example 1: sequence with a term to term rule of +3..

We add three to the first term to give the next term in the sequence, and then repeat this to generate the sequence.

## Example 2: sequence with a term to term rule of -1.

We subtract 1 from the first term to give the next term in the sequence, and then repeat this to generate the sequence.

We can work out previous terms by doing the opposite of the term to term rule.

2 Geometric sequences

A geometric sequence is an ordered set of numbers that progresses by multiplying or dividing each term by a common ratio.

If we multiply or divide by the same number each time to make the sequence, it is a geometric sequence .

Step-by-step guide: Geometric sequences

## Geometric sequences examples

Example 3: sequence with a term to term rule of ×2..

We multiply the first term by 2 to give the next term in the sequence, and then repeat this to generate the sequence.

## Example 4: sequence with a term to term rule of ÷2.

We divide the first term by 2 to give the next term in the sequence, and then repeat this to generate the sequence.

3 Quadratic sequences

A quadratic sequence is an ordered set of numbers that follow a rule based on the sequence n 2 = 1, 4, 9, 16, 25, … (the square numbers).

The difference between each term is not equal, but the second difference is.

Step-by-step guide: Quadratic sequences

## Quadratic sequences example

Example 5: sequence with common second difference of +2..

We find the first difference of the sequence and then find the term to term rule for the second difference. The second difference will always be the same for quadratic sequences.

4 Special sequences

You will need to be able to recognise some important special sequences.

## Special sequences examples

Example 6: square numbers.

A square number is the result when a number is multiplied by itself.

E.g. 1×1=1, 2×2=4, 3×3=9 etc .

The square numbers can form a sequence: 1, 4, 9, 16, 25, 36, 49…

n th Term = n 2

## Example 7: cube numbers

A cube number is the result when a number is multiplied by itself three times.

1×1×1=1, 2×2×2=8, 3×3×3=27 etc.

The cube numbers can form a sequence: 1, 8, 27, 64, 125 …

n th Term = n 3

## Example 8: triangular numbers

The triangular numbers as numbers that can form a triangular dot pattern. They are also special type of quadratic sequence.

We can generate a sequence of triangular numbers by adding one more to the term to term rule each time:

## Example 9: Fibonacci numbers

We can generate the Fibonacci Sequence of numbers by adding the previous two numbers together to work out the next term.

First and second terms :

We start with 0, 1

0+1=1 , so the third term is 1 .

Sequence : 0, 1, 1

Fourth Term :

Sequence : 0, 1, 1, 2

Fifth Term :

Sequence : 0, 1, 1, 2, 3

We can continue to follow the pattern to generate an infinite sequence.

The Fibonacci Sequence:

0, 1, 1, 2, 3, 5, 8, 13, 21 , …

The Fibonacci Sequence forms a spiral that is seen throughout nature.

## What are the four main types of different sequences?

## Sequence rule to find a term

We use the n th term of a sequence to work out a particular term in a sequence. By substituting in the number of the term we want to find as ‘ n ’ we can generate the specific term in the sequence.

What is the n th term and the 21 st term of this sequence?

4, 10, 16, 22, …

The n th term of this sequence is 6n – 2 .

To find the 21 st term, n = 21

(6 x 21) – 2 = 124

The 21 st term is 124.

Given the n th term rule, 3n + 4 , find the 20 th and 100 th term for this sequence.

To find the 20 th term, n = 20

(3 x 20) + 4 = 64

To find the 100 th term, n = 100

(3 x 100) + 4 = 304. The 20 th term is 64 and the 100 th term is 304.

## How to find the nth term of a sequence

The n th term is a formula that enables us to find any term in a sequence.

We will need to be able to find the n th term of a linear (arithmetic) sequence , and the n th term of a quadratic sequence .

We can make a sequence using the nth term by substituting different values for the term number n into it.

1 nth term of a linear sequence

In order to find the n th term of a linear sequence:

- Step 1: find the common difference for the sequence.
- Step 2: multiply the values for n = 1, 2, 3 , … by the common difference.
- Step 3: add or subtract a number to obtain the sequence given in the question.

## How to find the nth term of a linear sequence

## nth term of a linear sequence example

Find the n th term for the sequence 5, 9, 13, 17, 21 , ….

Find the common difference for the sequence.

The common difference d = 4 .

Multiply the values for n = 1, 2, 3 , … by the common difference.

Here, we generate the sequence 4 n = 4, 8, 12, 16, 20 , …. (the 4 times table).

Add or subtract a number to obtain the sequence given in the question.

The n th term of this sequence is 4n+1 .

2 nth term of a quadratic sequence

In order to find the n th term of a quadratic sequence we have to find the second difference. To do this, we calculate the first difference between each term and then calculate the difference between this new sequence.

- Step 1: find the first difference (d 1 ) and second difference (d 2 ) for the sequence.
- Step 2: Halve the second difference to find a , the coefficient of n 2 .
- Step 3: Subtract an 2 from the original sequence.
- Step 4: If this produces a linear sequence, find the n th term of it.
- Step 5: Add the n th term for the linear sequence to an 2 to work out the n th term of the quadratic sequence.

## How to find the nth term of a quadratic sequence

## nth term of a quadratic sequence example

Find the n th term rule of the quadratic sequence:

5, 14, 29, 50, 77 , …

Find the first difference (d 1 ) and second difference (d 2 ) for the sequence.

The second difference d 2 =6.

Halve the second difference to find a the coefficient of n 2 .

As d 2 = 6 ,

d 2 ÷ 2 = 6 ÷ 2 = 3

This means a = 3 and so we have the sequence 3n 2 .

Subtract 3n 2 from the original sequence.

Here, the remainder for each term is 2 .

Find the nth term for the linear sequence generated.

Not required for this example as the remainder is 2 for each term.

Add the nth term for the linear sequence to 3n 2 to find the nth term of the quadratic sequence.

The nth term of the quadratic sequence is 3 n 2 +2.

Step-by-step guide: Quadratic nth term

3 Use the nth term to calculate any term in a sequence

We can calculate any term in a sequence by substituting the term number into the n th term.

## nth term to calculate any term in a sequence example

Example 10: find terms in the sequence with nth term = 4n+1.

- For the first term, n=1

So 1st term = 4 ✕ 1 + 1 = 5

- For the 10th term, n=10

So 10th term = 4 ✕ 10 + 1= 41

- For the 100th term, n=100

So 100th term = 4 ✕ 100 + 1 = 401

## Example 11: find the first three terms in the sequence n 2 + 7n

- For the first three terms we use n=1, n=2 and n=3:

4 Use the nth term to work out whether a number is in a sequence

We can use the n th term to work out whether a number is in a sequence by putting the n th term equal to the number and solving the equation to find n .

Because n is the term number it has to be an integer (a whole number).

i.e. for the 1st term n=1 , for the 9th term n=9 etc .

When n is an integer then the number is in the sequence.

## nth term to work out whether a number is in a sequence examples

Example 12: when n is an integer then the number is in the sequence.

Is 25 a number in the sequence generated by the n th term 4n+1 ?

Let’s put 25 equal to 4n+1 and solve the equation.

As 6 is an integer this means that 25 is the 6th term in the sequence.

So 25 is a number in the sequence.

## Example 13: when n is not an integer then the number is not in the sequence

Is 60 a number in the sequence generated by the n th term 4n+1 ?

Let’s put 60 equal to 4n+1 and solve the equation.

As 14.75 is not an integer this means that 60 is not a number in the sequence.

5 Solve problems using algebra in sequences

We can write any type of sequence described above using algebraic terms rather than numerical terms.

For example, the sequence,

is an arithmetic sequence, because we add 2 each time to get from one term to the next.

We can apply skills such as solving linear equations and solving simultaneous equations to sequences with algebraic terms.

## Example 14: a Fibonacci sequence

The first three terms of a Fibonacci sequence are,

The 3rd term is 12.

Find the value of the 4th term.

First we form and solve an equation using the information given about the 3rd term:

We also need to find an algebraic expression for the 4th term. To get the next term in a Fibonacci sequence, we add the two previous terms. So the 4th term will be the sum of the 2nd and 3rd terms:

To find the value of the 4th term, substitute a=5 to get 3(5)+4=19 .

So the 4th term is 19.

Step-by-step guide: Sequences algebra

## Common misconceptions

- Arithmetic sequences are generated by adding or subtracting the same amount each time – they have a common difference d .
- Geometric sequences are generated by multiplying or dividing by the same amount each time – they have a common ratio r .
- Quadratic sequences have a common second difference d 2 .
- Mixing up working out a term in a sequence with whether a number appears in a sequence

In order to find any term in a sequence using the n th term we substitute a value for the term number into it.

- For the 5th term n=5 ,

So 5th term= 4(5)+1=21

- For the 8th term n=8

So 8th term= 4(8)+1=33

In order to work out whether a number appears in a sequence using the n th term we put the number equal to the n th term and solve it. If n (the term number) is an integer the number is in the sequence, if n is not an integer the number is not in the sequence.

Is 22 a number in the sequence with nth term = 4n+1 ?

As 5.25 is not an integer this means that 22 is not a number in the sequence.

## Practice sequences questions

1. Find the nth term of 1, 5, 9 ,13, …

The common difference here is 4 so it is 4n .

To get from 4n to our sequence we need to subtract 3 so our sequence is 4n-3 .

2. Find the nth term of 7, 4, 1,-2,-5, …

The common difference here is -3 so it is -3n .

To get from -3n to our sequence we need to add 10 so our sequence is -3n+10 .

3. Find the nth term of 6, 17, 32, 51, 74

Here the second difference is 4 . 4 \div 2 = 2

So it is 2n^{2}

We now need to work out the nth term formula for 4, 9, 14, 19, 24 ,..

The difference is 5 so it is 5n .

To get from 5n to our sequence we need to subtract 1 so it is 5n-1 .

The overall formula for the sequence is 2n^{2}+5n-1.

4. Generate the first 6 terms of the sequence 3n-4

5. Work out the 10 th term of the sequence 25-n^{2}

n=10 \begin{aligned} 25-10^{2}&=25-100\\ &=-75\end{aligned}

6. Write down the next three terms in this sequence: 0, 1, 1, 2, 3, 5, 8, …

This is the Fibonacci Sequence. We add the two previous terms to get the next term:

## \begin{aligned} 5+8=13\\ 8+13=2\\ 13+21=34 \end{aligned}

Sequences gcse questions.

1. (a) 5, 8, 11, 14

What is the rule to get from one term to the next?

(b) What is the n th term of the sequence?

2.(a)What is the 12 th term in the sequence 2n-20 ?

(b) Is 180 a number in the sequence?

## \begin{aligned} 2n-20&=180\\ 2n&=200\\ n&=100 \end{aligned}

Yes because n is an integer. 180 is the 100 th term in the sequence.

3. Look at this sequence 1, 2, 4, 8, 16

(a) What is the common ratio in the above geometric sequence?

(b) What would be the 7 th and 8 th term for the sequence?

7 th term= 32 \times 2 = 64

8 th term= 64 \times 2 = 128
