2022-07-06 Understanding Core Literacy in Middle School Mathematics Core Literacy Performance.

6 in high school, 7 in middle school, and 9 in elementary school + Applied Awareness, Creative Awareness.

Intuitive Imagination

Mathematical Insight:High School Mathematical Abstraction, Spatial Concepts, Geometric Intuition Middle School Abstract Awareness, Number Sense Quantitative Spatial Awareness, Geometric Intuition Elementary School Symbolic Awareness,

Mathematical Thinking:High School Logical Reasoning, Mathematical Calculations

Middle School Reasoning Skills, Arithmetic Ability

Elementary School Reasoning Awareness, Arithmetic Ability

p> Mathematical language: high school mathematical modeling, data analysis

Middle school modeling, data concepts

Elementary school modeling awareness, data awareness

Consciousness and concepts are knowledge of things, consciousness is based on intuitive senses, concepts are based on clear concepts of the connotations of the consistency of the expression of the phases, expressed in a holistic manner

Integration and practice to give specific content. Southeast, Northwest, and West

Project-based learning:Authentic contexts, interdisciplinary (10%) authentic problems, problem-solving format. Upper elementary, at least two per semester at the middle school level.

Traditional culture to have math

The story of the Chinese weighing:Recognize the dry grams tons and other equal and equal, the total is equal to the portion and the degree of the most weighing story, the story of the circumference of the Zai:Chinese traditional culture

A thematic integration:Primary school level

The field of number and algebra, six themes one or two themes of the recognition of the number of numbers + number of operations one of the number of numbers and operations of the common quantities of a synthesis and Practice

Equations I Middle School

Exploring Laws, Equations, and Proportional Quantitative Relationships

Graphics and Geometry area, four topics one or two topics

Graphical Awareness + Measurement I Circle Shape Awareness and Measurement

Graphical Motion + Shape and Position a State Shape Position and Motion

Subdivision of Core Content:

iii. Content Intersectionality:Number and Algebra

Elementary Middle School:Add two basic facts.

Transitivity: a=b. b=c-a=c;

Properties of equations: a=b→a+c=b+c

Elementary school decreases: equations, inverse proportions, and percents are moved to Statistics and Probability, and negative numbers are added to Synthesis and Practice. "Add: counting units, units of measurement that refer to number and order

Addition model, total = component + component

Middle school add: understanding the meaning of negative numbers (Example 64), nine chapters of arithmetic) equation cylinders

approximate calculations (Example 65); understanding algebraic reasoning (Example 66), divisible by 3; Vedic rationale adjusted from optional to Required.

Move the content of the percentage to "statistics and probability reason

Adapt to the requirements of the information age of big data era,

Guide students to establish data awareness digital literacy

Mining changes: certainty a certainty + randomness

Cash introduction: fruit counting content of a juice content of + cast Jane hit the trial.

The basis of the national development of the Blue Sky Program: the development of the fourth grade classmates of the jump rope standard middle school average of distributed operations, percent

Four content changes: graphs and geometry

Elementary school added: ruler gauge graphing.

Second semester making given line segments, expanded to making equilateral triangles with given line segments as sides. Third paragraph triangle perimeter, the three sides of the first and last fall in a straight line in turn.

Middle School added: ruler graphing requirements.

Over the circle outside - point for the tangent to the circle (will use the triangle ruler a ruler to draw)

V. Content changes: statistics and probability

Elementary school changes: classification of a classification of data (physical classification of an abstract classification), the percentage junior high school increase: the classification of the provincial GDP per capita: the difference between the group is large, the difference between groups is small

Distributed calculation of the mean (senior high school variance of the Distributed calculation)

Relationship between core content and core literacy

Concepts, properties, relationships, operations, laws, etc. of the object of study

It is the expressive form of mathematical content, which builds a bridge between mathematical content and core literacy

Bridge between mathematical knowledge and knowledge cognition

Focus on the teacher's teaching one focus on the student's learning three Focus on students' acquisition (not learning attitudes)

One knowledge acquisition, thinking acquisition

Concept-related content: closer to abstraction

Nature-related content: closer to reasoning

Relationship-related content: closer to modeling

Operationally-related content: closer to arithmetic
