贯穿各学习阶段的八种习惯数学实践
Move between quantities in context and symbolic representations while keeping meaning.
Justify a claim and examine another argument using appropriate evidence.
Choose a representation, state assumptions and check conclusions against the situation.
Choose and explain the use of diagrams, manipulatives, measurement tools or technology.
Communicate clearly using appropriate units, definitions, notation and accuracy.
Recognize and use parts, patterns and relationships to reason efficiently.
Notice repetition, formulate a general method and check whether it holds.
建模将数学与情境、假设和决策联系起来，贯穿整张图谱，并非独立年级或孤立主题。
图谱覆盖范围 · 来源与资源缺口
基础图谱包含全部 385 CCSS 数学内容标准及其 124 子项、十项学前数学目标和八项数学实践。主题分支将这些目标分组以便导航。高中 (+) 目标已包含并在详情中标注。可选的预备微积分和微积分纲要单独显示。
数学概念跨越国界，但年级安排和课程顺序各有不同。本参考图谱采用列出的美国课程框架。关联活动是资源库中精选的一部分，不代表每项标准都有练习，也不代表学习者已全部掌握。
Common Core State Standards for Mathematics (2010) ↗
K–8 content, all high-school content including (+), and eight mathematical practices. High-school modeling is a cross-cutting practice, not a separate collection of isolated targets.
Head Start ELOF: preschool mathematics (2015) ↗
All ten P-MATH goals; the map uses product-authored summaries and links to official developmental progressions.
