e) 48.3 x 6 __________________ f) 69.2 x 3 __________________
Choose 2 questions from above and calculate the actual product.
In math, students had a choice between two similar problems.
Your parents give you a choice on how to receive your allowance for the next 30 days. You can choose either:
A) $100 a day
or
b) $0.01 a day that is doubled each day. Example- Day 1- $0.01, Day 2- $0.02, Day 3- $0.04, Day 4- $0.08. The pattern of doubling continues each day.
How much money will you receive with choice A? How much for choice B? Which way will you choose and why?
Your parents give you a choice on how to receive your allowance for the next 15 days. You can choose either:
A) $10 a day
or
B) $0.01 a day that is doubled each day. Example- Day 1- $0.01, Day 2- $0.02, Day 3- $0.04, Day 4- $0.08. The pattern of doubling continues each day.
How much money will you receive with choice A? How much for choice B? Which way will you choose and why?
We will continue our work on this tomorrow.
In science, we learned about class and accidental characteristics and how they help investigators solve crimes. We were each given a photograph of the bottom of a shoe. We needed to find the person that had the same show print with us. Many of us used characteristics such as tread design and brand to find our shoe match. These are class characteristics. We then realized that there were shoes that there were 4 of each shoe that looked very similar. We then had to use characteristics such as worn patches, trapped rocks and dirt (accidental characteristics), cuts to find our identical shoe match.
Class characteristics- features that are common to all objects of the same variety and would not be able to highlight one particular shoe
For shoes- size, tread, brand, the colour, the material used to make the shoe...
Accidental characteristics- unique characteristics
For shoes- worn patches, holes, scuff marks, trapped dirt or rocks ...
We noticed that the images also had words and some of them had numbers. We decided that there was a secret message and worked together to figure it out. The message was, "Class and accidental characteristics can help us see just how unique each footwear impression can be and how and be and how a footwear impression at a crime scene can be as important as a fingerprint." Can you see any accidental characteristics in the picture of our shoes below?
Our day finished with us working on our guiding teaching page in our creative journals.
Reminders:
- Return Friday Journal (We had most returned today which is great!)
