Prime Numbers

To define what makes a prime number students begin the lesson by calculating factors of several integers.  Prime numbers are then defined and listed.  To aid their recollection of the first 12 primes students are challenged to apply them within calculations.  As learning progresses students use the Sieve of Eratosthenes to calculate all the primes up to 100.
Differentiated Learning Objectives
  • All students should be able to recall the first 12 prime numbers.
  • Most students should be able to recall and apply the first 12 prime numbers.
  • Some students should be able to use the Sieve of Eratosthenes to calculate all primes up to 100.

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 […]

How to Simplify Surds

When learning how to simplify surds students need to understand the difference between a rational and irrational number. Rational numbers include integers and terminating and repeating decimals. They can be written as a fraction with both the numerator and denominator as integers. An irrational number is a number which, in its decimal form does not […]

Sharing an Amount to a Given Ratio

There are three common methods for sharing an amount to a given ratio.  Depending on the age group and ability range I am teaching I would choose one approach over the other two. The three methods are: Using fractions Unitary method Using a table In this blog I will demonstrate each of the three methods […]
