Wednesday: Explorer Lab: The Demo-Week Tally

Librarian Joss sets a printout on the lab table. "The builder ran SH-1 for one demo week in another school's library. Here is every request."

Comet skims it. "Thirty requests. I bet most of them were Check. Students love being told they are right."

Wren clicks his pen. "What does the evidence say? Let's tally before we decide."

Nova draws an empty bar graph on the wall with three bars waiting to grow. "Would you like a hint?" she asks. "Count one day at a time, then add the days."

Comet writes her guess in the corner of her notebook and circles it.

Wren hands you the printout. "Reviewer, you count. We will check."

Your mission

USE-30 is the builder's list of 30 SH-1 requests from one demo week. It is a made-up example.

You will tally the requests by feature, then by kind of task. Then you will design two changes that make less new text.

Everything you need is on this page. You need no device.

  • Paper and a pencil
  • A ruler for the bar graph
  • Two colored pencils (optional, any colors)

USE-30, the demo-week requests (made up for the story). Each day had six requests.

  1. Write your prediction first: which feature was used most?
  2. Make a table with three rows: Ask, Quiz and Check.
  3. Go through Monday request by request, and make one tally mark for each one.
  4. Do the same for Tuesday to Friday.
  5. Count the marks in each row. Add the three totals and check that they make 30.
  6. Add Ask and Quiz together. That is the number of requests that made new text.
  7. Check is the number of requests that only labeled something.
  8. On graph paper or plain paper, draw a bar graph with two bars: making new text and labeling.
CHECK YOUR TALLY
  • Read the question.
  • Tap your answer.
How many Ask requests are in USE-30?
How many Quiz requests are there?
How many Check requests are there?
How many requests made new text (Ask plus Quiz)?
WHAT THE TALLY SHOWS
  • Read the question.
  • Tap your answer.
Comet guessed most requests were Check. Was she right?
What fraction of the 30 requests made new text?
Suppose every Quiz request used a bank of quizzes a teacher already checked. How many requests would still make new text?
Why can the crew still not give an energy number for SH-1?

Design two changes

The crew wants SH-1 to make less new text without hurting students.

Here are two ideas they wrote. A quiz bank: teachers keep the quizzes they have already checked, and students reuse them.

A paper option: every task can also be done on paper, so nobody has to use SH-1 for practice.

Your job is to design one more change of your own.

On paper, draw your bar graph of making new text and labeling. Under it, write the two crew changes and one change of your own.

Excellent counting, reviewer. Tomorrow the crew traces everything SH-1 is built from.
