Finding the Highest Common Factor

Students learn about finding the highest common factor of numbers and terms.  More able student learn how to find the highest common factor of expressions.At the start of the lesson students recap finding factors of numbers and simple terms.  In the main phase they find the factors of numbers and terms to select the highest factor that is common to all values.  At the end of the lesson they are challenged to solve a real life problem by finding the highest common factor of two numbers.
Differentiated Learning Objectives
  • All students should be able to calculate the highest common factor of two integers when given their factors.
  • Most students should be able to calculate the highest common factor of two or more integers.
  • Some students should be able to calculate the highest common factor of two or more terms.

Showing Progress during a Mathematics Lesson

Demonstrating student progression during a mathematics lesson is about understanding the learning objective and breaking that down into explicit success criteria. Using Success Criteria Take, for example, a lesson on calculating the area of compound rectilinear shapes. The intended learning objective was written on the main whiteboard. Success criteria were used to break down the individual […]

Plotting and Interpreting Conversion Graphs

Plotting and interpreting conversion graphs requires linking together several mathematical techniques.  Recent U.K. examiner reports indicate there are several common misconceptions when plotting and interpreting conversion graphs.  These include: drawing non-linear scales on the x or y axis, using the incorrect units when converting between imperial and metric measurements, taking inaccurate readings from either axis not […]

Calculating the Volume of a Pyramid

When calculating the volume of a pyramid we can substitute the values of the length, width and perpendicular height into the formula V = 1/3 lwh.  In my experience this is often provided for the students with little explanation as to why a volume of a pyramid is exactly one third the volume of a […]
