Renaming Numbers- A creative activity using the Linear Abacus®

Explore how numbers are modelled on the Linear Abacus® using base 10 notation, and discover how to rename numbers (i.e., find equivalent names for numbers) using the Linear Abacus® as a calculating device to model the arithmetic.
Renaming is an important mathematical idea and is used when calculating with algorithms and when computing mentally. For instance, say you wanted to multiply 12 x 8, but could not recall this fact. Having the skill to think about numbers flexibly will allow you to decompose and recompose numbers to simplify the question e.g., 12 can be thought of as 10 and 2. This means you could multiply 8 x10 then 8 x2 and add the totals: 80 +16 = 96.
In this activity Genovieve Grouios demonstrates how renaming is shown as a process used to describe where a number is in an order. This video uses the number 56 as an example. Clear demonstrations and explanations are included to make the content accessible.
Children will develop the skills to reason with models and symbols and will learn to think flexibly with numbers.
