Spin and Sort – More, Less, Same

This activity is best used in amath centerorguided small group来练习comparing numbers。

资源包括：

• a spinner
• “更多”，“少”和“相同”分类垫
• 指令表。

怎么玩

在卡片纸上打印排序垫和旋转器，以增加耐用性。切出箭头并将其连接到旋转器上。或者，使用大型纸夹进行旋转器。学生将纸夹放在旋转器的中心，并用铅笔的橡皮面固定。然后，他们将纸夹重击，使其可以在旋转器周围旋转，直到它落在其中一侧。

Students randomly choose a number as their “focus number.” Alternatively, provide students with a deck of number cards to draw from each time. Students will spin the spinner. If the spinner lands on “more,” they will generate a number of items that is greater than their focus number and place the pile in the “more” section of the sorting mat. Students continue to spin and generate numbers, placing the piles in the appropriate sections of the mat.

使用此资源的其他方法

该资源可以通过多种不同的方式使用。

掩饰

Students spread out an assortment of number cards in front of them. After selecting one of the number cards as their “focus number,” they spin the spinner. The spinner directs where they will place a counter – either on a number card that is more, less, or the same.

跳上数字线

将旋转器与数字线结合在一起。一个人将计数器放在数字线上的数字上。他们还抛弃了死亡，并旋转了旋转器。下一个人将计数器移至数字线上的正确位置。为了扩展活动，让学生创建一个数字句子以匹配每次的举动，例如7 - 2 = 5。
