Multiplying decimals using the grid method
When multiplying a decimal over one (such as 2.4) by a one-digit number, the grid method can come in handy. By Y6 your child will know how to use the grid method and they will also already know how to multiply a decimal under one by a one-digit number. They just need to put these two skills together for this activity!
Multiplying and dividing decimals
When you want to multiply a decimal by a one-digit or two-digit number, you can use the long multiplication method. It is very important to remember to line up your numbers correctly
or your decimal point will end up in the wrong place! Practise these sums using this method.
Multiplying using long multiplication
A quick way to multiply a three-digit number by a two-digit number is by using the long multiplication method. Here are some for you to try (there are some multiplications with four-digit numbers in here, but don’t worry, the method is still the same!). Use the boxes to help you set out your numbers correctly!
Multiplying fractions
When multiplying two fractions together, you quite simply multiply the numerators and then multiply the denominators. Work out the answers to these number sentences by multiplying both the numerators together and both the denominators together. Shade the diagram to show that you have found a fraction of a fraction.
Multiplication and division calculations matching
Melissa has checked her multiplications by using division. Which calculations do you think she used? Match the correct pairs of multiplication and divisions.
Multiplying a three-digit number by a two-digit number with the grid method
To use the grid method when multiplying large numbers you will need to partition numbers and put them in a table. Use this method to work out these sums.
Mental multiplication and division of decimals
Use your knowledge of times tables to work out these sums involving multiplying and dividing decimals.
Square numbers
When you multiply a number by itself, the result is a square number. Cut out these cards and see if you can pick out the square numbers.
Multiplying decimal numbers by one-digit numbers
If you are multiplying a decimal by a one-digit number, it is a good idea to multiply the decimal by 10 first to make the calculation simpler. Don’t forget to divide the answer by 10, too! Use this method to help you work out these sums.
Doubles up to double 5
When you double a number you add it to itself, so double 5 means 5 + 5. Use the teddy number line to help you solve these double problems!
Multiplying pairs of multiples of 10
Here are a few techniques you could try to multiply pairs of multiples of 10. Can you use one of these techniques to answer these questions?
Multiplying and dividing by ten and a hundred
When multiplying by ten, numbers move one place to the left. When multiplying by one hundred, numbers move two places to the left. When dividing by ten, numbers move one place to the right. When dividing by one hundred, numbers move two places to the right. Use this method to work out the answers to these questions.
Multiplying a three-digit number by a one-digit number with the grid method
The grid method is a good way to multiply three digits by one digit. To do this you will need to partition your numbers and put them in a table. Can you use the grid method to work out these sums?
Finding multiples
Draw a line to match these numbers to the correct multiple underneath. (Remember, some numbers have more than one multiple.)
Finding factors
A FACTOR is a whole number that multiplies with another whole number to make a third number. Can you find all the pairs of factors for these numbers?
Decimals: doubling and halving
When doubling and halving decimals it is sometimes easier to imagine them as two-digit numbers. See if you can double and halve the following decimals, using the knowledge you already have of doubling and halving other numbers.
Using a calculator for two-step problems
You can use a calculator for these two-step problems. What calculations will you need to do? Think hard about what numbers you need to key in and what you will need to write down as you go along.
Solving two-step problems
Can you solve these problems? Jot down the numbers you need to use on the notebooks. Think about the steps needed to work out these problems and jot numbers down as you go along. Ask a parent if you need help finding one half and one fifth of a number.
Mental maths checker: doubles and halves of two- and three-digit numbers
Can you double and halve these two- and three-digit numbers? Colour in a star every time you get 10/10!
Multiplying with the partitioning method
When multiplying a two-digit number by a one-digit number, use your partitioning skills to split up the two-digit number and multiply each digit in turn. It works in exactly the same way as the grid method… just without the grid! Use this method to multiply these numbers.
