In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

Learners examine the information on a title block and answer questions about that information in an interactive quiz.

In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.

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

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.

In this animated and interactive object, learners view American National Standard and International Standard sheet sizes. A quiz completes the activity.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.

Learners examine pictorial drawings used in engineering including sectioned and exploded drawings. A sketching quiz is provided to help the learner create simple pictorial sketches by using orthographic views and an isometric template.

In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.

The learner will represent very large and very small numbers in engineering notation.

Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.

In this learning activity you'll practice converting between degree minute second and decimal degree.

Students read how to lock a cell that is being referenced in a formula so that it does not automatically show an increment when the formula is copied.

Learners follow step-by-step instructions for calculating the square root of a number using the TI-83 Plus scientific calculator. Steps for determining impedance are also shown.

Learners view the steps to find the complex conjugate of a number in polar form using a TI-86 calculator.

This primer introduces the student to the proper use of the "EE" function to perform calculations on very large or very small numbers.

Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object.

Learners read how to raise a number to a power using the TI-86 calculator. Examples are given for both real and complex numbers.
