When introducting long multiplication into the curriculumn, educators know that there will be some fairness, hesitation, and difficulty when present to students. There are some students who will find it easy and grasp the material easily. Then there will be some students who truly find it difficult to do and they may become frustrated and flustered. When I was in school multiplication was introduced one type of way, with a number on the type, a multiplying number on the bottom and a line underneath it. Until this day I still multiply my numbers the same way, but times have changed and math as evolved so there are an abundant amount of methods that can be used for long multiplication.
Once the students have watched the video they can be given more than one method ot find the product of there multiplication problem.
The first method of finding the answer to long multiplication is a COLUMN METHOD.
A second method that can be demonstrated for students is the Lattice Method.
By providing students with different methods to solve a long multiplication problem we are offering students different choices to choose from to retrieve the correct and same answer.
CCSS.MATH.CONTENT.4.NBT.B.5
Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
