**Some good Maths Projects.**

**The Little Red Tractor.**

**The Little Red Tractor.**

**The little red tractor. This project is suitable for good 13, 14, 15 year old students.**

**There are several ways of working this problem out. One of the ways is quite simple!**

**The formula which is obtained for cutting a paddock measuring x metres by y metres is quite useful !**

**Print and then photocopy the page for your students. It is a good project for them to work on. **

**It takes about 1.5 to 2 hours of work and easy to assess.**

**I assess it on a graded system of **

**A+, A, A-, B+, B, B-, C. **

**A+ is outstanding with extra relevant material added **

**and a **

**C grade is unsatisfactory! **

**These grades can be converted to marks when needed.**

** A+ = 10, **

**A = 8, **

**A- = 6, **

**B+ = 4, **

**B = 2, **

**B- = 0, **

**C = redo!**

**The aim of this Mathematical Digest site is to give teachers and students access to interesting and useful mathematics, project material, challenges, mathematical applications, and teaching tips! It will also give students and parents mathematical challenges!**** **
