Especially for children who have struggled with maths in the past, it's easy to lose confidence. The grid method can look intimidating at first, and some children get so nervous they simply stop being able to work through the steps logically. Reassurance will do wonders here, as will working through a couple of examples together slowly. When you've multiplied the ones digit by every digit in the top number, move to the tens digit in the bottom number.The first number, 23, is made up of the number 20 and the number 3. That means we need to write 20 and 3 in the boxes to the right of the X. Use long addition to add your number columns from right to left, carrying as you normally do for long addition.

Proceed right to left. Multiply the ones digit of the bottom number to the next digit to the left in the top number. If you carried a digit, add it to the result and write the answer below the equals line. If you need to carry again, do so.

If your child is struggling with the grid method despite your best efforts, here are our top three suggestions to help. Kidadl provides inspiration to entertain and educate your children. We recognise that not all activities and ideas are appropriate and suitable for all children and families or in all circumstances. Our recommended activities are based on age but these are a guide. We recommend that these ideas are used as inspiration, that ideas are undertaken with appropriate adult supervision, and that each adult uses their own discretion and knowledge of their children to consider the safety and suitability.

Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top number Most children won't have covered decimal multiplication in Lower KS2, so convert the numbers to pence before you start. Then, work through the grid as if you were multiplying a three-digit number by a one-digit number. Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand.History/origin: The milli- prefix is one of many metric prefixes. It indicates one thousandth of the base unit, in this case the meter. The definition of the meter has changed over time, the current definition being based on the distance traveled by the speed of light in a given amount of time. The relationship between the meter and the millimeter is constant however. Prior to this definition, the meter was based on the length of a prototype meter bar. In 2019, the meter has been re-defined based on the changes made to the definition of a second. In some ways, this is even easier than the grid method example above with a 2-digit number, since using a 1-digit number means there's only one row to deal with. We just need an extra column in for the hundreds. Then, follow the same method as above, multiplying each number in the top row by the one in the left-hand column: Now, we just need to add all the numbers together. Take all four of the answers you have just found, and write them out as a column addition (or whichever addition method the child you are helping is most comfortable with): This step-by-step breakdown shows how to use the grid method to solve a variety of multiplication problems your children are likely to encounter in school. This might be simple money questions in Year Three all the way up to multiplying 4-digit numbers in Year Six. What Is The Grid Method?
