- describing the relationship between mL and L
- selecting and justifying referents for mL or L units
- estimating capacity by using referents for mL or L
- measuring and recording capacity (mL or L).
[C, CN, ME, PS, R, V]
(a) |
Show, using concrete materials, that 1000 mL has the same capacity as 1 L. |
(b) |
Provide referents for 1 millilitre and 1 litre and explain the choice. |
(c) |
Describe strategies for selecting and using referents to determine approximate capacity measurements in situations relevant to self, family, or community. |
(d) |
Decide what standard capacity unit is represented by a specific referent, and verify. |
(e) |
Estimate the capacity of a container using personal referents. |
(f) |
Determine the capacity of a container using concrete materials that closely take on the shape of the container, describe the strategy used, and explain whether the volume is exact or an estimate (e.g., if beads are used, discuss the impact on accuracy because of the space between the beads compared to the accuracy if water is used). |
(g) |
Sort a set of containers from least to greatest capacity, explain the strategies used, and verify by determining or estimating the capacity. |
