      'My Favorites' is a special kind of lens which you can use to bookmark modules and collections directly in Connexions. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need a Connexions account to use 'My Favorites'.

      Definition of a lens

      Lenses

      A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

      What is in a lens?

      Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

      Who can create a lens?

      Any individual Connexions member, a community, or a respected organization.

Module by: Angela Chen

Summary: This document tests use of non-breaking spaces, and super and subscripts set in Word.

0 to 1, or Never to Always

Intent

In this activity, students work with probabilities expressed as fractions, percentages, and decimals.

Mathematics

Students continue to focus on the distinction between probability based on a theoretical model and probability based on observed results and on measuring probability using a real-number scale from 0 to 1.

Progression

Earlier in the unit, students estimated the probability of given events. In this activity, they invent situations that match a given probability.

Approximate Time

5 minutes for introduction

25 minutes for activity (at home or in class)

10 minutes for class discussion

Classroom Organization

Individuals or pairs, followed by whole-class discussions

Doing the Activity

Clarify that students are to invent two situations for each question, one based on theoretical probability and the other on observed results. Let's test a link to Keypress.com by clicking here.

  1. Here is an equation with a non-breaking space: x + y = z
  2. Here is a test of subscripts and superscripts: x2 + y2 = z1 + z2

Discussing and Debriefing the Activity

If students have worked individually, ensure that there is time for them to compare their invented situations. Question 5 is included to give students an opportunity to consider an impossible situation.

Key Questions

Does it matter whether probabilities are written as fractions, decimals, or percents?

Why is the smallest probability 0?

Why is the largest probability 1?

What does a probability of 2.3 imply?
