In this learning activity you'll explore family structure then enter terms in a grid identifying if that family structure is determined by females, males, or both.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

Learners practice reading prints of a hub. They identify information located on the print and calculate missing dimensions.

In this animated print reading exercise, the learner calculates missing dimensions and identifies surfaces on projected views.

Material condition modifiers may be applied to tolerances for geometric characteristics of features of size. A feature of size is one that can be measured across two opposing points, either internally or externally.

In this animated object, learners read the dimensions of the different types of vehicles typically considered in highway design.

The learner examines the four different ways that a caliber can be used to measure dimensions and distances.

In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

The learner will measure and record dimensions using a metric micrometer to an accuracy of plus or minus .01 of a millimeter.

Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.
