Off-the-shelf Primary Mathematics Masterclass all about big and small numbers.
Explore mathematical techniques for manipulating numbers from the minuscule to the huge. Test students' skills at estimation along the way by sampling small amounts and scaling up.
Being able to easily handle very big and very small numbers when studying mathematics and other subjects is very important. In this session, the students are introduced to notational ways of handling these types of numbers.
Once they have mastered these basic skills, explore interesting methods for approximation and try out some fun and unusual estimating activities such as how many books are there in the library and cake sprinkles in the jar!
Length: 2 hours (see the session leader notes for ideas on how to shorten the Masterclass).
All supporting notes, worksheets and solutions can be downloaded from this page along with the Powerpoint presentation.
The Session Leader Notes offer full notes on the activities and a detailed list of resources, including quantities needed. For additional guidance, the session script gives a full run-through of the Masterclass.
The Session Helper Sheet can be distributed amongst helpers and an Additional Information Sheet giving more details on the history and background of the subject is provided for added interest.
