数单位立方体
Counting Unit Cubes
通过数单位立方体来测量体积,使用立方厘米、立方英寸、立方英尺等单位。
Measure volumes by counting unit cubes using cubic cm, cubic in, cubic ft, and other units
学习证据 / Evidence
- 在三维示意图中数单位立方体,以立方厘米(cm³)为单位确定体积。
- 通过用1立方厘米的小正方体装满一个小容器,测量它的体积。
- 用正确的立方单位记号表示测量得到的体积。
- Count unit cubes in a 3D diagram to determine volume in cm³
- Measure the volume of a small container by filling it with centimetre cubes
- Express a measured volume using the correct cubic unit notation
评估问题 / Assessment
如果{{name}}在图中看到一个由小立方体搭成的立体图形,能数出里面有多少个小立方体吗——包括藏在后面的那些——从而算出体积?
If {{name}} sees a 3-D shape built from small cubes in a diagram, can they count how many cubes it contains — even the ones hidden at the back — to find the volume?
