# 加拿大论文代写被发现：数学教学拓展

Through different game modes, such as dice and chips, block object, all students can be involved in interaction to compete, with a figure rising to tens digits, hundreds digit, in this game in natural solution place the value of teaching; the game method is very suitable for used in teaching, it can be used to explain the concept that is difficult. This week, there was focus on four operations, finding balance between estimation, mental computation, writing algorithms and understanding the calculator. The biggest gain that was made was to use the number plan to keep the balance, relationship between number and numbers in week 5. This is a kind of orderliness between numbers, such as the graph as follow.A picture, with a yellow sign digital all can be divisible by three, chaining together with the brown line numbers can be evenly divisible by 9. This multiple of nine is divisible by three. Figure 2 is about four times table. Figure 5 is about 6,7,8,9 multiples. It is the duty of the teacher to help students find out the rules about numbers and analysis, understanding of these laws.

When student understand these basic rules they are easy to remember and extend more knowledge about mathematics.In week six again there was focus on two aspects, one is about the operation of fractions. When an object is divided into a number of equal parts the with part is called a fraction .The other is about how to analysis and computation number .Fraction is a difficult subject in basic mathematics, but through week 6, teacher can use it for different applications to integer factorization, better enable students to understand what is a grade. At the same time, it can partition size of graphics to make the students understand the scores of several times it is simple for the scores of operation. The other problem is promoting number sense to the students. The good way is to draw a grid the size of the multiplication problem, draw diagonals to show the tens/ones place.
