Boxes method, this is where we split each number into its parts.
The standard algorithm is generally a faster method but, unlike the area method, it does not promote understanding or encourage the development of mathematical thinking.
Activity: Modeling 5 x 14 with Cuisenaire Rods.For example 400 30 is the same as followed by 3 zeros, because there are 3 zeros altogether in 400 and.Here is a worked solution using the boxes method: 475 x _ 17100 So the answer is 17100 grams.You need to be able to understand multiplying with powers of 10 to know how many zeros to put on the end.Now multiply by 6: 158 x 6 7 _, now add your two rows together, and write your answer.Check with your teacher to make sure you know which paper is the non-calculator exam).158 x 6 7 _ _ 10586, so the answer is 10586.To calculate 158 67: 158 is 100, 50 and.Use the example below to show the correlation between the two methods Example Area Method Standard Algorithm 5 2 1 x Multiplication Worksheets Use the worksheets below to practice using the area method for multiplication as well as other methods.
For both long multiplication and long division, there is an alternative to the traditional method.
10 4 5 times (5x) means we need five (5) 14s.
