Maths during 1950 s The mathematic textbooks of the 1950 were mainly written by teachers and super visors who had the knowledge of maths at an undergraduate level. Very few people had accomplished the equivalent of a bachelor’s degree in mathematics. More often this education had been at a teacher's college, with only very few teachers, super visors, cur riculum consultants, textbook writers, or even professors of maths. However there was a renewed interest in mathematics education emerged in the 1960 s, and the International Commission was revitalised Source: http: //web. math. rochester. edu/ people/faculty/rarm/intro. html and Marriotts Maths teachers

Grid Method In maths at the level of primary school or elementary school, the grid method which is also known as the box method of multiplication is used as an introductory approach to multi digit multiplication. The Grid method differs from the traditional long multiplication method as it consists of breaking the multiplication and addition into two steps and being led dependent on place value. Although some may argue that the grid method is less efficient than the traditional method it is considered more reliable as children and adults are less likely to make mistakes. The grid method is considered to be a starting block of multi digit multiplication therefore once the grid method was mastered most pupil went on to learn the traditional method.

Grid Method Step by Step The grid method is a useful starting point when first learning to multiply. STEP 1: When using the grid method, split each number into tens and units to make multiplying easier. For example, if multiplying the numbers 34 x 18, you will split the number 30 into 10, 10, 4 on the horizontal side of the grid and 18 into 10, 8 on the vertical side of the table. 10 10 10 4 10 8 STEP 2: After you have simplified each number into units 10 10 10 4 and tens you multiply each number by one another and 100 100 40 10 fill the grid in. 80 80 80 32 8 STEP 3: Once all the grid is filled in, you take all the numbers and add them together to get the answer. 34 x 18 = 612 100 100 80 80 80 40 32 612
