FormRanger Add-On

I love me some Add-Ons. One of my favorites is FormRanger from New Visions Cloud Lab. It can be used to pull in a column of information from a Google Sheet as multiple choice or dropdown options.

This is nice for quickly creating a lot of options for a multiple choice or dropdown question, but what takes it from nice to awesome is  . . . you can set it to automatically update based on changes made to the spreadsheet. Whaaaaat!?  I know, right?

There are two main cases for use: Continue reading FormRanger Add-On

FILTER Formula in Google Sheets

You can filter using menu buttons and create filter buttons in Google Sheets, but sometimes it’s valuable to setup a FILTER formula.  One such instance is shown in the GIF below: when you have a Sheet that contains data about many students across many grades or classes.  Using a filter formula, you can create a tab for each class or grade.  You can also create tabs for certain criteria (like lower scores that require follow-up).

=FILTER(range, condition1, [condition2, …])

Note from the formula above, that you can actually identify multiple criteria (such as Mr. Kotter’s students who scored below a 75%).

Exploring the Number pi with Google Sheets & Forms

What better way to celebrate Pi Day than with a hands-on, tech-on exploration activity that helps students build their own understanding of what pi really is?  Well, probably a good piece of pie, but this is awesome nonetheless.

Here’s what you do:

  1. Get a bunch of fabric tape measures (using string and then measuring lengths on the string works too).
  2. Get a bunch of circular objects.
  3. Have kids measure the circumference and diameter of different circular objects.
  4. Instruct the kids to submit their measurements to a Google Form
    (note: my form doesn’t collect names, but it would be best to collect them so you can help kids who have measurement errors).
  5. Setup a QUERY formula to find the circumference/diameter for each entry.
    =QUERY(B2:C1000, “select B/C”)
  6. Fix that pesky 2 in the Query formula after the first submission – when the first entry inserts a row, it changes B2 to B3.  Change it after the first entry and you’re good to go.
  7. Setup an AVERAGE formula to find the mean of the circumference/diameter calculations.
  8. Project the spreadsheet as entries are recorded.  See what your kiddos notice about the numbers they see on their screen!

Locate your Collaborator by Clicking on their Icon

Wait, what page are you on?
I’m confused.  What slide are you referring to?
Ugh, what cell are you in!?

GSuite’s tools make collaboration–both between adults and between students–a piece of cake, but it can still be tough to keep up with one another, especially in lengthy Docs, Sheets or Slide decks.  Did you know that if you click on their icon it will jump you right to their location?  You’re welcome.

Check out the two GIFs below . . .

Exploring Measures of Center with Google Sheets

My obsession with Google Sheets is no secret. I loooove spreadsheets.  And I think that they have a big place in education, especially in math (but elsewhere as well).

Recently, I posted about how you can prove the mean (or average) formula using Google Sheets.  In this post, I’d like to share with you how you can find all 3 measures of center (or measures of central tendency) and explore them in Google Sheets.  I love to change or add numbers in the data set and ask students to make predictions about what will happen.  It really is a great–and relevant–way for students to become more familiar with these statistical measures.

Proving the Algorithm for Mean (Average) in Google Sheets

I am a huge spreadsheets nerd and a huge advocate of the use of spreadsheets in mathematics instruction.  If you keep an eye on my site (or Twitter feed or YouTube Channel) you’ll see plenty of my reasons why I feel this way.  Here’s one:

Spreadsheets are a great tool for proving mathematical algorithms and formulas.  In this post . . . how we can use a Google Sheet to prove the formula for the mean (which, in spreadsheet land, is known as the average).
