《十大正规网赌软件》

十大正规网赌软件相信每个孩子的才华. Kindergarten is going to be a great year where your child will use math to answer their questions about the world.

In Kindergarten your children will focus on three important areas of mathematics that are aligned with the Common Core standards – Counting, 加减法, and Shapes.

Counting: 在学习数数时，有三个重要的技巧需要练习:

  1. 学生学习认识数字名称和数到100的数列.
  2. 学生在数数的时候学习, each object counted or touched corresponds to a number in the counting sequence (one to one correspondence).
  3. Students learn that the last number in their count tells them ‘how many’ objects were counted (Cardinality).

把数字放在一起和分开: Students talk about numbers and play with objects to understand how quantities can be combined to make numbers up to ten or broken apart into smaller quantities. These skills are used to explore numbers between 11 and 20 and the place value system.

Shapes学生将学会识别, classify, 并根据边缘的数量等特征组合形状, angles, and curves.

See the parent guide in the right-hand column or the unit descriptions below for more details.

经常和孩子一起练习数数. They should know how to count to 10 and beyond and understand what the numbers represent. 玩包含计数的游戏, 比如捉迷藏, 把数数融入到日常活动中, 比如爬楼梯或者吃东西.

幼儿园数学单元划分

第1单元:从数字到5 & 数到10

在这个单元中，学生们开始发展计数的原理.

Comparing and counting small numbers is an important step for students who may already know the number names and or sequence. Developing relationships between language and the quantitative element of these small numbers is crucial.

第二单元:大小、顺序和位置

In this unit, students compare objects and discuss attributes like number of sides or size.

  • 学生们使用诸如“更长”之类的词汇, “taller”, “more”, “wider”, “next to”, “beside”, “under”, etc.
  • 学生将比较抽象的形状，如圆圈和现实生活中的物体. And compare shapes to each other to find differences in attributes and measures.
  • Students are also working on number comparison as they line up groups of objects or consider number of sides, 来决定哪一组拥有的更多更少.
第三单元:从数字到10

In this unit, students build upon unit 1, where they counted objects through 10.

  • 学生继续以1:1的比例计算.
  • 学生将与 计数集合 数量20-30.
  • Students will be composing, decomposing, comparing and ordering numbers up to 10.
  • Students will develop the generalization that the next number we say in the counting sequence is one more than the current number.
  • Students will begin to use identify how many are in a group and how many are in two groups joined together
第四单元:从数字到20

本单元建立在第三单元:数字到10的基础上. Students will be learning to read and write numbers to 20 and will be developing mastery of 1-1 correspondence when counting up to 20 objects.

  • 学生培养对“青少年”数字的理解.
  • Use ten frames 为了表明数字是由10和其他的1组成的.
  • Develop understanding of the ‘Ten’s Place’ and that it represents a full ten frame.
  • 比较和排序最多20个对象的组(从最小到最大).
第五单元:几何

In this unit, students learn to recognize and name a variety of plane and solid shapes, 并且组合和分解这些相同的形状.

  • Students understand that certain attributes define what a shape is called (number of sides, 角度数, etc.)和其他属性没有(颜色、大小、方向).
  • Students use geometric vocabulary to distinguish between figures that are 2-D plane shapes (squares, circles, triangles, rectangles, 六边形)和三维立体图形(立方体), cones, cylinders, and spheres).
  • Students use position and size vocabulary to compose new shapes from two or more primary shapes.
第六单元:从数字到100

数到100是幼儿园小朋友的年终目标. 学生将继续使用合唱数数和数字对话, 和计数集合，以进一步发展其计数原则.

  • Ten frames continue to be used to understand the tens place and it’s relationship to the ‘decade’ numbers (20, 30, 40…)
  • Continue to explore the composition of teen numbers (a ten and additional ones) and make connections to non-decade numbers greater than 20.
  • 使用“百位”图表在我们的数字系统中建立模式.
第七单元:比较集合

The focus of this unit is on comparing objects with measurable attributes and academic vocabulary.

  • 学生将数量与数字配对.
  • Compare sets using academic vocabulary to determine if the number of objects in one set is greater than, less than, 或者等于另一个集合中物体的个数.
  • 在比较集合时，学生可以使用 匹配策略，计数策略 或者平分策略.
  • Develop a conservation of number – understanding that moving objects in a group does not change the quantity of objects.
第八单元:加减法策略

In this unit students have many opportunities to represent addition and subtraction problems with concrete objects, pictures, and words.  Students are beginning to make sense of the relationships between quantities as they decide what actions to take in order to solve a problem.

  • 这是介绍毅力概念的好时机. Encourage students to try a different way to solve a problem if they get stuck, 并思考答案是否合理. It is important to ask students probing questions such as “How do you know?来引出他们的想法.
  • 学生们将发展出一种“指望”加法的策略.
  • Also, a ‘counting on or back’ strategy for finding the difference between numbers.
  • 学生将把这个计数和数轴联系起来.
第九单元:组成和分解数字

在这个单元中，学生们继续练习他们的数数能力, understanding of quantities and begin to reason about and solve addition/subtraction expressions and equations.

  • Review the decomposition and compositions of numbers to 5 to reinforce numerical part whole relationships.
  • 分解和合成是同时使用的 number bonds to understand the part / whole relationships for combinations within 10, before adding & 减法算法.
  • 学生与 5和10帧来分解、重组和求和数字.
  • Most elementary level story problems are part/part/whole or comparison problems.
第10单元:测量

In this unit students get to explore what it means to measure or quantify our world.  他们将有机会测量和比较长度, height, distance, weight, volume, and time.

  • All the standards in this unit can be addressed by comparing objects and discussing attributes.
  • 学生们使用诸如“更长”之类的词汇, “taller”, “more”, “wider”, etc.
  • Students will distinguish measurable attributes like a cans’ Hight or weight from non-measurable attributes like brand of soda in the can.
  • 学生将在许多经历中使用非标准的度量单位. 用回形针来测量，而不是抽象的thing called an inch, makes the concept of measurement more real to young people. 
  • This gives students a chance to focus on the concept of length or weight without being distracted by learning a fixed system of units.
