This is a game for two players. You should know how to find the mean, median, mode and range of a set of numbers.

Players take it in turns to throw (click on) the 3 dice. The player then chooses either the mean, median, mode or range of the scores and claims a square (if that value is available).

A square can be claimed by clicking it once for red and twice for blue.

The first player to claim four squares, arranged together as a larger square or in a line, is the winner.

Half-court Rounding is a game in which students try to score as many points as possible by rounding numbers to the nearest ten, hundred, or tenth. This is a perfect game across grade-levels, because students can choose to shoot free-throws (1 point - round to the nearest ten) jump shots (2 points - round to the nearest hundred) and three-pointers (round to the nearest tenth). Users can try any kind of shot within the game and have 90 seconds to score as many as points as possible and beat their opponent. If they answer incorrectly, the student misses the shot. Students can also choose a two-player game where they can play a friend or classmate.

But these pesky Screech Owls make nothing easy. Rather than just telling the elevator escort what room they are in, they make him figure out an addition or subtraction decimal problem! Worse yet, this hotel's rooms are numbered by decimals! The good news is the Snowy Owl escort receives a $5.00 tip for each Screech Owl he delivers successfully. If the escort brings the Screech Owl to the wrong room, however, he loses $5.00!

At timestables.co.uk you can easily practise all of your tables. The arithmetic problems are clear and simple so you can immediately get started on practicing your tables. Select one of the times tables you wish to practise from the list below and show what you can do on the speed test, Multiplication Tables Check or printout great worksheets.

Choose the table you want to practise from the following. First you can practise the times tables in sequence and once you have got the hang of that you can practise all the sums in random order for each table. If you have forgotten any answers, just go back to the 'all tables in sequence' page and practise them again thoroughly before trying again.

Once you have got the hang of a number of tables you can select the speed test and choose the tables you want to practise getting quicker at. If you make a mistake, you came see what the right answer is at the end of the test. This will help you learn all of your tables. The speed test is good practise for getting your tables diploma. On the tables diploma the questions are a bit quicker than on the speed test, but if you get all of them right you will get your tables diploma. There are two tables diplomas. The little diploma is made up of 30 questions. Your little diploma shows you can do the 1,2,3,4,5 and 10 times tables. For the big tables diploma you are given 40 questions which include all the tables from 1 to 12.

Learn the times tables in an interactive way with the free math times tables games KS2 and KS1. The game element makes it even more fun learn.

Practise your times tables

Here you can find additional information about practicing times tables at primary school. The 1 times table, 2 times table, 3 times table, 4 times table, 5 times table and 10 times table are usually the first times tables which have to be learned. The 6 times table, 7 times table, 8 times table, 9 times table, 11 times table, 12 times table and of course all the tables in random order are the next step. This is part of KS1 and KS2.

New is the Multiplication Tables Check, this is a key stage 2 assessment to be taken by pupils at the end of year 4, from the 2019 / 2020 academic year onwards. With this check there are asked 25 questions on the times tables 2 to 12.

Not every child finds it easy to learn all the tables, so it is a good idea to keep on practicing them regularly after year 5. There are a few tricks which make it easier to learn the tables and continue to master them, such as putting the smallest number first, which makes it easier for many children to answer correctly. For example 4 x 9 is easier to work out than 9 x 4. Switching the multiplication sum around makes it easier to answer. What also often helps is to use the tables you know well for answering the sums in the more difficult tables. One example of this is 6 x 7, which is often said to be tricky. If you do 5 x 7 first and then add 1 x 7 it is suddenly easier to answer. You can do this the other way round too. For instance with 4 x 7 you can do 5 x 7 first then subtract 1 x 7.

Why do we put so much effort into learning tables? Well, the times tables keep on coming up in the next primary school years and even when you're at secondary school. You don't see them as tables, but as part of bigger mathematical problems. And it isn't only at school, but in your everyday life it is useful to know your times tables well so you can quickly work things out, for instance when you are buying or selling vegetables on the market. If you have any questions, comments or ideas for timestables.co.uk, please use our contact form. We'd be glad to hear from you.

The 5-step plan

Learn the times tables with the 5-step plan. We developed an innovative five step plan to help pupils learn the times tables in an effective and efficient way. This method has been tested at several schools and is recommended by teachers.
The steps are:

Step 1a: View, read aloud and repeat. To get familiar with the table.

Step 1b: Fill in your times tables answers in sequence and check if you got them all right.

Step 2: Drag the correct answers to the questions.

Step 3: Fill in your answers for the mixed questions and check if you got them all right.

Step 4: Multiple choice questions will help you to improve by looking at the questions in a different way.

Step 5: Proof your knowledge and get the diploma.

When you finished the 5 steps you can play the memory game or exercise with the worksheet. Other way to train more are with the tempo test, the 1 minute test or to play the times tables games.

We advise to exercise daily for 15 minutes for maximum result.

Practise your times tables online

Times tables are important and there are not many places where you can learn them quickly and easily, so we have come up with timestables.co.uk! Practicing your tables online is really easy at timestables.co.uk. The times tables games are clear and simple so you can get started right away. Click on one of the tables to get started right away. Fill in the answers in the lines and when you've finished, click on 'check'. You will see right away which answers are correct and which are incorrect. You can also practise different times tables in one exercise so you can test whether you know them all and yu can also look at the times table grid or times tables worksheets.

You can also practise the tables interactively with the free multiplication games. On the times tables games page we now have an answer-dragging game and a table balloons game.

Times tables form the basis for the calculations that you do in the following years, so it's important that you fully understand them.

Do you want to practise more math? Go to Mathdiploma.co.uk - Here you can practise addition, subtraction, multiplying, dividing and a lot more!

We also have a fraction website! On Fractionsweb.co.uk are lots of exercices about simplifying, adding, subtracting, dividing and multiplying fractions. There are fraction games, worksheets and 5-step plans!

Factorise algebraic expressions in this structured online self marking exercise.

This is level 1: factorising an expression with a constant factor. You can earn a trophy if you get at least 9 questions correct and you do this activity online.

Order the terms in your answers in the same order as they appear in the question.

Description of Levels

Close

Level 1 - Factorising an expression with a constant factor.

Example: 40h + 88

Level 2 - Factorising an expression with a variable factor.

Example: 23h + 3h²

Level 3 - Factorising an expression with both a constant and variable factor.

Example: 10a + 2ab

Level 4 - Completely factorising an expression of two parts that can be separately factorised.

Example: 3a + ab + 5w + 4wy

Level 5 - Writing an expression as the product of two binomials.

Example: 5a + 5b + ac + bc

Level 6 - Factorising an expression which is the difference between two squares.

Example: c² - 81

Level 7 - Factorising a quadratic where the squared term coefficient is 1.

Example: c² - 13c + 36

Level 8 - Factorising a quadratic where the squared term coefficient is not 1.

Example: 4a² + 5a - 6

Examples

This program checks your answers by matching the text you have typed in with the options it has as the correct answer. For that reason it does not always recognise equivalent correct answers. For example the factorisation of 6a+21 can be written as 3(2a+7) or 3(7+2a) but the program may only recognise the first option as the correct answer. Please type in your answers so that the terms are in alphabetical order of the variables followed by the constants unless a negative cooeficient of the viariable makes the opposite a more elegant solution.

Level 1 example: \(40h + 88\)

Identify a common factor of 8 to give \(8(5h+11)\)

Level 2 example: \(23h + 3h²\)

Identify a common factor of h to give \(h(23+3h)\)

Level 3 example: \(10a + 2ab\)

Identify a common factor of 2a to give \(2a(5+b)\)

Level 4 example: \(3a + ab + 5w + 4wy\)

Identify common factors of pairs of terms to give \(a(3+b)+w(5+4y)\)

Level 5 example: \(5a + 5b + ac + bc\)

Extract common factors of pairs of terms to give \(5(a+b) + c(a+b)\)
Then extract a common factor of (a+b) to give \((a+b)(5+c)\)

Level 6 example: \(c² - 81\)

This can be written as \( (c+9)(c-9) \). Expand the brackets to see why

Level 7 example: \(c² - 13c + 36\)

Start by finding two numbers with a product of 36 and sum of -13
These numbers are -4 and -9
So the factorisation is \( (c-4)(c-9) \)

Level 8 example: \(4a² + 5a - 6\)

Multiply the coefficient of a² by the constant term: \( 4 \times -6 = -24 \)
Now find two numbers with a product of -24 and sum of 5 (the coefficient of a)
These numbers are -3 and 8
Write the original expression with the middle term split into these two numbers: \( 4a^2-3a+8a-6\)
Extract common factors of pairs of terms to give \( a(4a-3) + 2(4a-3)\)
Then extract a common factor of (4a-3) to give \((a+2)(4a-3)\)

Level 9 example: \(b² + 6b + 9\)

Use the techniques used in the previous levels

Don't wait until you have finished the exercise before you click on the 'Check' button. Click it often as you work through the questions to see if you are answering them correctly. You can double-click the 'Check' button to make it float at the bottom of your screen.

Answers to this exercise are available lower down this page when you are logged in to your Transum account. If you don't yet have a Transum subscription one can be very quickly set up if you are a teacher, tutor or parent.
