Swimming Through The Year With MissThresher: More Data and Chance stuff!!!

The past week and a half has all been about chance and data in the Dugong classroom an OH BOY have we been busy!!!

After creating our class life sized picture graph of how we travel back from school we created picture graphs using the information we had gathered in a tally. We answered different questions about our graphs using both the information we could easily see and using our other skills like addition and subtraction!

By the time Friday came along we were in need of some extra motivation so the good old m n m’s came out! You could hear a pin drop when I handed the packets out!

We made our expectations very clear so m n m’s did not go ‘missing’ during the lesson!

First we compared how many m n m’s we each had in our packet. On average we had 13/14 m n m’s. I have done this previously where the numbers range from 12 - 17!!!!

Then we divided the m n m’s into colours and tallied this information. Next we used our tally to create our own bar graph!

After this we looked at pie charts! We used our m n m’s to help us create our own bar graph. We did this by placing the m n m’s around a circle cut out and then placing a dot in the middle to help guide our lines!

Check out the final product!!!! - Sorry it is upside down but you get the idea ;)

This week we moved onto chance! We talk about the likelihood of events both in the students’ personal lives and of our world!

Finally today we looked at the probability of chance outcomes!!! We looked at bags of marbles and discussed the likelihood of pulling out particular colours.

I made some mystery bags up filled with 3 colours of marbles. Each bag contained 6 marbles however they were mixed in terms of the number of each coloured.

Students worked in pairs to pull out one marble at a time, record its colour and then place it back in the back. THEY WERE NOT ALOUD TO PEEK IN THE BAG!!!!
