Math Practice for Multiplication
Multiplication Hints Can Save Your Child Time and Worry
Taking timed tests can be quite overwhelming for kids, which can leave them overwhelmed with basic math facts that they should know backwards and forwards. By teaching them some math shortcuts with Math Practice , you can help them in not wasting time on basic mathematical facts and can give them some confidence in knowing how to find answers without counting on their fingers, etc. What are some basic multiplication shortcuts and hints that can help your child on their next timed test?
The Power of Nines. The single digit 9 times table can be rechecked by your child very easily. Notice below:
See? The answer of their single digit nines tables should always add up to 9. This is a great trick to help your child check their answer when they are faced with a problem from the single digit nines.
The Facts of Fives. While the 5’s times tables are normally the easiest, it can still be one that will fly out of your child’s head when they are under the gun of a timed test. Here is a little help for your child. One trick to start with is that an even number multiplied by 5 will always have an answer that ends in 0, while an odd number multiplied by 5 will always have an answer that will end in 5. Another trick for even numbers is below.
Look at the tens digit of the answer. If you look at it versus the number we are multiplying by, you will notice that it is half of that number. This works for even numbers that are being multiplied by 5. What about odd numbers? See below.
On the odd numbers, you minus one from the number you are multiplying by five and then divide that answer by two. This should be the first number of your multiplication problem and, since it is an odd number, it should end in five. This is a great way for your child to check their answer when they are multiplying by 5.
Easy problems can help with harder problems. For example, your child may know their tens times tables backwards and forwards, but 19x7 may have them stumped. Explain that they can jump up to the easier problems of 20x7=140 and then subtract 7 from that to get 19x7=133. This can save them time over figuring it the long way. This will work with any problem that is near the times table that they are most comfortable with to allow them to check their answer and not have to work it out the more complex way.
Test taking is hard on any child, but by giving them little hints and tips throughout the year when you are helping them with their math homework, you can better prepare them for their timed tests that normally come at the end of the school year. In addition, you will help them with their schoolwork throughout the year, especially in checking their math facts as they are doing multiplication problems and math practice, as well as instilling confidence in them of their own abilities.
