Animal World Records...

Students were given records from the Guiness Book of Records and in groups of three had to replicate the measurements AND fill in the missing gaps thinking about possible scales. I was very impressed with the creativity given the limited size and colours of the chalk sticks. The sizes of some of these animals were positively mammoth.  The accuracy was uncanny given students only had one hour and twenty minutes to consult with each other, sketch out preliminary measurements, draw and shade. Amazing team work! The drawings were enjoyed by all students and staff who visited the courts at lunch time and throughout the following day.  The students  then sat or laid next to their creations to get a real feel for the size of them! I love their impersonations of the animals.

Tomato Sauce Investigation - August Focus - ReportWriting - Due in Thursday 3rd September

Over the next few weeks students will be conducting a predominantly mathematical investigation into different brands of tomato sauce. This will allow them to focus on nutrition information panels, gain an understanding of milligrams, grams, unit pricing, data collection, the program Excel and the ingredients of tomato sauce, most notably the quantities of sugar, fat and sodium. There are ten brands under scrutiny some of which claim to be organic and healthy. I purchased ten types to make use of percentages a little easier for students.  The Spelling Bingo words for this week and next will be words students will be using in their investigations. Students have checked the reliability of their data and can now start their reports. I have shown them the basics of Excel and they have access to examples of finished reports done by a cohort some years ago who used a different selection of sauces. The students have posed two main question to investigate:
Which tomato sauce brand in the sample group is the healthiest and which is the least healthy?
Which tomato sauce is best vale for money (per hundred mls)?

We estimated what 100 mls was
