Practice multiplication with arrays using this set of 20 task cards in a variety of ways.
什么是乘法中的数组？
The array method is another way of solving multiplication equations.通过使用符号将乘数分解为同等数量，并将其排列成排和列，我们可以更轻松地可视化其产品。
For example, to represent the乘法方程4×2 = 8，您的数组看起来像这样：
Four rows with 2 triangles in each row or 4 groups (rows) of 2.
用数组练习乘法
Through this activity, students will show they can代表乘法facts使用阵列方法。
为了播放，学生将计算每个数组的行和列，并确定相应的乘法事实。然后，他们将编写乘法事实，并在其录音表上求解其产品。
一旦填补所有空间，学生就可以在中间时间与随附的答案密钥检查录音表，以使自己负责。
脚手架 +扩展技巧
通过向学生展示如何跟踪乘数来支持帮助理解概念的学生。将他们的工作表滑入干擦套筒中，并为学生提供可擦除的标记，使学生在计算时圈出行。
学生也可以参考锚图或乘法事实海报以供指导。
Challenge快速完成者他们已经理解了使用操纵剂来重新创建阵列并通过交换行和列来练习交换属性的概念。
More Ways To Show Multiplication Using Arrays
我们为您创建了此资源math center作为独立练习活动。我们还建议通过以下方式使用它来加强您的小组和全班课程：
画廊步行（踏板活动）
Hang all task cards around the room to have your students complete a gallery walk. Working either alone or in pairs, assign a task card to each student and have them write their answers on the recording sheet. When you say, “Scoot,” students will rotate through the cards until they have completed each one.
Bell Ringer Activity
项目a selection of array cards for your students to see as soon as they enter the classroom. On a piece of paper or mini whiteboard, have students write the multiplication array presented and solve for the product. Discuss the solution and process during your math lesson as a quick recap.
退出活动
课后，将卡片作为数学问题传递给学生，他们将独立回答。向他们提供自己的粘纸笔记，以便他们可以作为形成性评估来转动答案，并确保在粘性笔记上写下他们的名字（或使用我们的名字粘附印刷指南 +模板）。
轻松为您的学生准备此资源
Print on cardstock for added durability and longevity. Place all pieces in a folder or large envelope for easy access.
要将任务卡放在口袋或桌子下方，请在每个角落打一个孔，将它们放在粘合剂环上。
可持续性提示：在卡片纸上打印一些录音纸，然后将其滑入干式套筒中。学生可以使用干式校友标记记录答案，然后擦除和重复使用。
Because this activity includes an answer sheet, we recommend first printing one copy of the entire file. Then, make photocopies of the blank worksheet for students to complete.
