- selecting and justifying referents for the unit mm
- modelling and describing the relationship between mm, cm, and m units.
[C, CN, ME, PS, R, V]
(a) |
Choose and use referents for 1 mm to determine approximate linear measurements in situations relevant to self, family, or community and explain the choice. |
(b) |
Generalize measurement relationships between mm, cm, and m from explorations using concrete materials (e.g., 10 mm = 1 cm, 0.01 m = 1 cm). |
(c) |
Provide examples of situations relevant to one's life, family, or community in which linear measurements would be made and identify the standard unit (mm, cm, or m) that would be used for that measurement and justify the choice. |
(d) |
Draw, construct, or physically act out a representation of a given linear measurement (e.g., the students might be asked to show 4 m; this could be done by drawing a straight line on the board that is 4 m in length, constructing a box (or different boxes) that has a base with a perimeter of 4 m, or carrying out a physical movement that results in moving 4 m). |
(e) |
Pose and solve problems that involve hands-on linear measurements using either referents or standard units |
