Probability and Graphs

We had a very energetic math lesson today! We started out with a look at a probability line and discussing the meaning of these probability words:

impossible, unlikely, equally likely, likely, certain

Students debated the likelihood of various scenarios to demonstrate their understanding of each probability word. Oral language skills were put to good use as students argued their points of view.

Then, students were given the task of rolling 2 dice 30 times and recording the sum. They worked in pairs to collect their data.


The next task was to choose an appropriate graph to display their data.  Some students chose to create a stem and leaf plot with the reasoning that it was quick and easy to do.

But then, our discussion lead to the conclusion that this was not the best way to display the data as it was difficult to answer questions about the data. Students concluded that a bar graph or a line plot were better choices.

We discussed the similarities in the shape of the data and discovered that the sum of 6 has the greatest chance and the sum of 2 and 12 have the least chance.  We created a frequency chart as we investigated the possible dice combinations and students made observations about patterns! It was a very rich discussion!

Lastly, as one group had mistakenly recorded differences instead of sums, we turned the mistake into a learning opportunity and we compared their graph to the rest only to discover a similar shape in data!

It was an extremely fun, learning inquiry in math today!

Creating Okies

This art project started out with a social studies lesson courtesy of the Simcoe County Museum:

The Wendat believed that everything in the world around them, from trees to
lakes to rivers to animals, possessed a soul or spirit, called an oki. Different okies
could bring good or bad luck in different human activities, from travel to war to
hunting or fishing to farming to gambling to relationships.
• Wendat people enlisted help from a particular oki by carrying a charm dedicated
to them. These charms could be highly valued and could be passed on from one
generation to the next. Charms could be made or could be found in the woods,
where it was believed that they had been lost by the spirit that made them.
Charms could also be obtained through trade from the Algonquins, who were
such good hunters and fishermen that they were considered very lucky people.
• Wendat people carried their good luck charms around with them. If they needed
help from their charm’s oki, they would speak to the charm and offer it beads or
pieces of tobacco as presents. They could also hold feasts for their okies to
make them more powerful.
• These charms will be made from clay. Clay was one material that the Wendat
used often to make important items like pipes and pots. They could embellish
clay objects by drawing designs on them using wooden sticks.

Then it was on to creating our own okies! Students learned how to start with a ball and use a pinch method to form features. They learned how to use slip to repair/prevent cracks. Students discovered that while an artist may start with one idea for a sculpture the project may turn into something completely different as the clay starts to form.

These charms are wonderful!

Tumbling Silhouettes

Students combined their knowledge of colour, using water-colour paint, body shape and proportion to create this project. After having created foil sculptures students had some background in creating movement in a figure, thinking about body parts and joints.

The final projects are fantastic!
