Chapter 12 Discovering Systematic Procedures

In this way, the childâ&#x20AC;&#x2122;s natural and free exploration of informal methods would not be discouraged. 2 The second step would be to introduce a fixed procedure by relating it to the pupilsâ&#x20AC;&#x2122; previous experiences. Even when pupils are studying numbers up to 1000 it is best to introduce the process with a group of numbers totaling less than 100. Working first with the rods, the pupils can be led to understand the principles involved in the procedure, enabling them at a later stage to work with great confidence on larger numbers. This can be shown by taking the sum 16 + 34 + 24 as an example. The three trains of rods representing these numbers are first made. (For greater clarity, the rods as shown here as separate entities, although they would of course, be placed end to end.)
