Dominotion (part 1)

I love the satisfaction you get from creating something. Like a new blog post. But creation requires effort.

As Mathematics teachers, we create lessons for our students. The content of these lessons can come from many sources. eg. Videos, worksheets, games, text books, puzzles, card matching, etc.

One of my most successful methods of creating original content is to start with “material”. eg. cards, blocks, dominoes, dice, cardboard, paper, etc.

My most recent purchase was a double 15 set of dominoes from a “Games World” store in Perth.

double 15 dominoes

The first questions that come to mind are:

  1. How many dominoes? (don’t show students the tin)
  2. Total number of dots?
  3. What size rectangles can be made?

Another application is to use dominoes to represent fractions. For example find equivalent fractions, sort fractions in ascending order, etc.

4. What fraction of the 136 dominoes form proper fractions that can be simplified?

Any other ideas – I would love to hear from you.

Stay tuned for (part 2) of this post where I introduce a new game called “Dominotion”.
