1. |
Estimate the size of an object or compare objects with respect to a given attribute (such as length, area, capacity, volume, weight/mass) |
 |
 |
 |
|
2. |
Select and use appropriate measurement instruments (for example, manipulatives such as ruler, meter stick, protractor, thermometer, scales for weight or mass, gauges) |
 |
 |
 |
|
3. |
Select and use appropriate units of measurement according to: |
|
|
|
|
a. Type of unit |
 |
 |
 |
|
b. Size of unit |
 |
 |
 |
|
4. |
Estimate, calculate (using basic principles or formulas), or compare perimeter, area, volume, and surface area in meaningful contexts to solve mathematical and real-world problems |
|
|
|
|
a. Solve problems involving perimeter and area (such as triangles,
quadrilaterals, other polygons, circles, combined
forms)
[Note: Grade 4 tasks
use manipulatives] |
 |
 |
 |
|
b. Solve problems involving volume and surface area (such as
rectangular solids, cylinders, cones, pyramids,
prisms, combined
forms)
[Note: Grades 4 and 8 use
manipulatives]
|
 |
 |
 |
|
5. |
Apply given measurement formulas for perimeter, area, volume, and surface
area in problem settings |
 |
 |
 |
|
6. |
Convert from one measurement to another within the same system (customary
or metric) |
 |
 |
 |
|
7. |
Determine precision, accuracy, and error |
|
|
|
|
a. Apply significant digits in meaningful contexts |
 |
 |
 |
|
b. Determine appropriate size of unit of measurement in problem
situations |
 |
 |
 |
|
c. Apply concepts of accuracy of measurement in problem
situations |
 |
 |
 |
|
d. Apply absolute and relative error in problem situations |
 |
 |
 |
|
8. |
Make and read scale drawings |
 |
 |
 |
|
9. |
Select appropriate methods of measurement (such as direct
or indirect) |
 |
 |
 |
|
10. |
