# Length

# Teaching Ideas

Length measurements are used to measure how long, how tall or how far apart objects are.

# Area

# Teaching Ideas

Area measurements are used to measure the amount of space a 2-D object takes up.

# Volume

# Teaching Ideas

Volume measurements are used to measure the amount of space a 3-D object takes up.

# Capacity

# Teaching Ideas

Capacity measurements are used to measure how much an object can maximally hold.

# Mass

# Teaching Ideas

Mass measurements are used to measure how much material there is in an object. It is sometimes confused with weight, which is how much pull gravity has on an object.
