乘法中的阵列

用阵列表示乘法和除法情境

Use arrays to represent multiplication and division situations

学习证据 / Evidence

• 摆出一个3行、每行4个物体的阵列来表示3 × 4
• 观察一个阵列并说出总数
• 利用阵列解决简单的除法问题（例如：把12个物体每4个排成一行，能排成3行）

• Build an array of 3 rows of 4 objects to show 3 × 4
• Read an array and state the total
• Use an array to solve a simple division problem (e.g. 12 objects in rows of 4 → 3 rows)

评估问题 / Assessment

如果{{name}}看到盒子里有3行4列摆放的鸡蛋，能利用这种阵列算出“3 × 4 = 12”和“12 ÷ 3 = 4”吗？

If {{name}} sees eggs arranged in 3 rows of 4 in a box, can they use that grid layout to work out both '3 × 4 = 12' and '12 ÷ 3 = 4'?
