Alternative Number Systems

Students investigate alternative number systems including the Roman and Egyptian systems.  Less able students create a system similar to the Romans that counts numbers above one.  More able students are challenges to use a different base.  This lesson links well with history and human development.At the start  students recap how to multiply and divide by a power of ten.  In the development phase they compare and critique number systems to our own decimal system.  Later on students are create their own number system and teach it to their peers.
Differentiated Learning Objectives
  • All students should be able to convert to and from Roman and Egyptian Numerals.
  • Most students should be able to compare and critique alternative number systems to our own decimal system.
  • Some students should be able to recognise the importance of zero in creating an effective number system that includes proportionate amounts.

Comparing Datasets using the Mean and Range

In my experience, students, in general, find the concept of a mean straightforward to calculate and understand. However, the mean alone does not provide a complete picture of a set of data. To achieve this, a measure of spread is also required. The range is the simplest measure that can be used for this. Not […]

Solving Problems with Angles in Parallel Lines

Solving problems with angles in parallel lines is like solving a murder mystery.  One clue leads on to the next and the next until the murderer is found.  However, it doesn’t end there.  The detectives need to explain their reasoning in court using the relevant laws and procedures should the murderer plead not guilty.  If […]

Solving Two Step Equations using the Balance Method

An equation is when one expression, or term, is equal to another.  To solve an equation means to find the value of the variable (represented by a letter) that makes the two expressions equal.  There are two types of equations for secondary school mathematics, linear and none-linear.  In this blog I write about how I […]
