Calculate elapsed time to the minute (limited to 2 adjacent hours)

Find beginning and/or ending time, given elapsed time (limited to 2 adjacent hours)

Convert linear measurements within the same system:

Mm - cm - m -km

In - ft - yd

Use a ruler to measure to the nearest ¼ inch or millimeter.

Perimeter and Area:
