英語の勉強

”教科書のあり方などに相違点がある。例えば日本では乗法に関して、「九九」すなわち9×9の数表を教え暗記させているが、インドでは「20×20」(19×19) の数表を教え暗記させている。また、日本では「2+3=□」というタイプの、答えが基本的には一つしかないような課題が主として出されるのに対し、ヨーロッパなどでは初期の段階から「□+□=5」といったような課題を頻繁に提示し、答えが一つではなく複数あり、様々な数学的な発想・探求へといざなうような教育がされることが多い。
中国、台湾、韓国、北朝鮮では、「算数」ではなく「小学数学」と呼ばれている。

Strands of Elementary Mathematics
Number Sense & Numeration
Number Sense is an understanding of numbers and operations. In the number sense and numeration strand students develop an understanding of numbers by being taught various ways of representing numbers, as well as the relationships among numbers.

Properties of the natural numbers such as divisibility and the distribution of prime numbers, are studied in basic number theory, another part of elementary mathematics.

Elementary Focus

Fractions and Decimals
Place Value
Addition and subtraction
Multiplication and Division
Counting Money
Counting
Representing and ordering numbers
Estimating
Problem Solving
To have a strong foundation in mathematics and to be able to succeed in the other strands students need to have a fundamental understanding of number sense and numeration.

Measurement

Measurement skills and concepts are directly related to the world in which students live. Many of the concepts that students are taught in this strand are also used in other subjects such as science, social studies, and physical education[6] In the measurement strand students learn about the measurable attributes of objects, in addition to the basic metric system.

Elementary Focus

Standard and non-standard units of measurement
telling time using 12 hour clock and 24 hour clock
comparing objects using measurable attributes
measuring height, length, width
centimetres and metres
mass and capacity
temperature change
days, months, weeks, years
distances using kilometres
measuring kilograms and litres
determining area and perimeter
determining grams and millilitre
determining measurements using shapes such as triangular prism
The measurement strand consists of multiple forms of measurement as Marian Small states " Measurement is the process of assigning a qualitative or quantitative description of size to an object based on a particular attribute."

Equations and formulas

A formula is an entity constructed using the symbols and formation rules of a given logical language. For example, determining the volume of a sphere requires a significant amount of integral calculus or its geometrical analogue, the method of exhaustion;but, having done this once in terms of some parameter (the radius for example), mathematicians have produced a formula to describe the volume: This particular formula is:
V = 4/3 π r3

An equation is a formula of the form A = B, where A and B are expressions that may contain one or several variables called unknowns, and "=" denotes the equality binary relation. Although written in the form of proposition, an equation is not a statement that is either true or false, but a problem consisting of finding the values, called solutions, that, when substituted for the unknowns, yield equal values of the expressions A and B. For example, 2 is the unique solution of the equation x + 2 = 4, in which the unknown is x.”
