1. What makes shapes alike and different can be determined by geometric properties.

2. Shapes can be moved in a plane or space.3. Shapes can be described in terms of their location in a place or 

space. 4. Shapes can be seen from various perspectives.

Sep 29­11:57 AM

1. Measurement involves a comparison of an attribute of an item or situation with a unit that has the same attribute.

2. Meaningful measurement and estimation of measurements depend on personal familiarity with the unit of measure being used.

3. Estimation of measures and the development of benchmarks help students increase familiarity with units.

4. Measurement instruments are devices that replace the need to actual measurement units.

5. Area and volume formulas provide a method of measuring these attributes by using only measures on length.

6. Area, perimeter, and volume are related. 

Measurable Attributes

Length, time, money, weight, mass, volume, perimeter, area, angles

Measurement Big Ideas

Sep 29­11:57 AM

What is a unit of measurement?

Standard and Non‐standard Units

Sep 29­11:57 AM

Length ­ practice with standard (U.S. and metric) and non­standard units.What level of precision is required?Measurement is always an estimate.

Time ­ one­handed clocks, time to the 5 minute

Money ­ practice with real world situations 

Weight and mass ­ balance, units

Sep 29­11:57 AM

Perimeter ­ 1 dimensional, geoboards, other shapes

Area ­ 2 dimensional, cover surface so the units need to cover surface, geoboards with various shapes

Volume ­ 3 dimensional, fill up container, use units that are 3­D. Cube activities 

Angles ­ corners, protractors
