Lesson: Get the Point

Title

Get the Point

Description

A lesson about the use of pixels, points and picas in design

Summary

Because of the need for precision, visual journalists rely on a unique system of measurements to fit components together. This unit introduces students to pixels, points and picas, the importance of using these measurements in design, and how to convert from inches to picas and points. Students will apply their knowledge of conversions to calculate sizes of objects, line up components in a composition and create components of specified measurements. Finally, students will draw their own shapes based on preset dimensions.

Objectives

  • Students will be able to recognize pixels, points and picas as units of measurement.
  • Students will be able to convert inches to points and picas.
  • Students will be able to convert points into picas and picas into inches.
  • Students will be able to apply picas and points by drawing shapes of specified dimensions.
  • Students will be able to draw and place shapes on graphing paper or using desktop publishing software based on preset specifications and locations.

Lesson step-by-step

1. Introduction — 20 minutes

After showing samples of several designs (magazine spread, website, newspaper front page), connect to the idea that any type of design is based on organizing or arranging elements. Introduce key terms: gutter, column guides, grid guides, alley, pixel, points, picas. (See Handout 1.1a). Students will use Handout 1.1b to convert inches and other measurements into picas and points. Demonstrate the conversions on the board as students follow along. After going over the steps to convert, students will try to convert the four examples in the handout. To earn credit, students must show their work.

2. Build skills — 25-30 minutes

To reinforce the concept of points and picas, students will apply their knowledge by converting numerous shapes and equations in the Conversion Exercises handout.

3. Guided practice — 30-35 minutes

Using the 2-D Shapes handout, students will draw a series of objects according to specified dimensions. Students can complete drawings using blue graphing paper or with computer software. Students will submit their completed handouts for evaluation at the end of the period.

4. Closure — 5 minutes

Exit card: Students will calculate the size of the room and convert from feet to inches, then to picas. (Prior to this activity, you will need to measure the classroom.) For a 20’ x 32’ room, the dimensions would be 240” x 384” — 1,440p0 x 2304p0 in picas.
