Engage your students with our ready-to-go packs of no-prep games and activities for a range of abilities across Kindergarten to Grade 5! The standard algorithm for multiplication can be very difficult to teach in 5th and 6th grade, as anyone who has taught upper elementary school before will know. Despite best intentions, there will always be a few students who are either unsure of the methods they used for multi-digit multiplication before or who are not secure on their multiplication facts. Before you learn the standard algorithm for multiplication, you typically understand multiplying multi-digit numbers in parts and adding the partial products at the end. In the standard algorithm, it is more of a shorthand way of multiplying in parts, while doing some of the addition at the same time as multiplication. It is often referred to as multi-digit multiplication and is the recommended method to use when multiplying larger numbers. Before tackling the standard algorithm, students should ideally be confident with their multiplication facts and understand key terms like the multiplicand and the multiplier. Help your students learn their times tables from , spot patterns, and learn about factors and multiples with this handy printable multiplication chart. They will do this through methods such as area models and partial products. It is crucial that students become fluent in the method to enable them to access more challenging math as they progress to middle school and beyond. In middle school, students will build on this skill and multiply multi-digit decimals. When I say fluent this is what I mean:. Read more: Fluency, Reasoning and Problem Solving. The formal standard algorithm is a step by step method of supporting children to understand conceptually and practically how to multiply multi-digit numbers, and is typically introduced when students begin to multiply large numbers.

In case you or your students want to make up your own questions, these blanks should expedite the process.

Long multiplication or column multiplication is a written method of multiplying numbers usually a two- or three-digit number by another large number. It is usually used in Year 5 and Year 6 once children have got the hang of using the grid method. The benefit of the grid method is that it encourages children to think about place value and multiply multiples of ten and one hundred. Once they have got the hang of this, long multiplication is a faster, more efficient technique to use. As in column addition and column subtraction , the numbers are positioned in a column as follows:. Here is an example of an array to demonstrate 5 x 3 or 3 x

The standard algorithm examples Standard algorithm questions. In my experience, I have not come across many students whose prior-attainment means they cannot set out the column method of multiplication correctly. As with our full library of lessons, each one includes questions to ask, ways to support students when they are stuck, and answers to the given questions. Identify common factors, common multiples and prime numbers. What are multiples and factors? The single digit column and row numbers are multiplied together and their product is written in the corresponding box, separating the tens and ones places on either side of the diagonal. This strategy is not for every multiplication problem, but it certainly works well if certain numbers are involved. The answers use a paper and pencil algorithm that is commonly used in the U.
