Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen.
Shape, Dimension, and Geometric Relationships
- Understand quantity through estimation, precision, order of magnitude, and comparison. The reasonableness of answers relies on the ability to judge appropriateness, compare, estimate, and analyze error
Some attributes of objects are measurable and can be quantified using different tools
Measure and estimate lengths in standard units.
