The Directress directs the child to choose from the right set of rods. The child chooses a rod, for e.g. a 5 rod.</li><li>Then the Directress places the 5 rod just below the 7 rod, and then says, "how many more to make 7?" The child then counts out the number rod to make 7 based on the 7 rod which acts as control of error and would probably answer "2". Then the child takes a 2 rod and places it besides the 5 rod below the 7 rod and would find them at equal length.</li><li>Directress then explains, "5 plus 2 makes 7" and then shows the child how to write "5 2=7" on plain square paper.</li><li>The Directress can continue the presentation by showing a few more examples.</li></ul>
 
=== Control Of Error ===
The Rods themselves act as a Control of Error because the quantities are fixed.
 
=== Points Of Interest ===
As a preparation to learn Number Bonds, when doing the above exercise, we could always exchange places between the 2 addition rods and reinforce that, for e.g. 5 2=7 and 2 5=7 as well. Exercises should not be called 'sums' as in correct mathematical language the 'sum' is the answer to an addition question. We use 'exercise or 'example' instead.
 
=== Purpose ===
<ul><li>Introduce the child to addition with numbers 1 to 10.</li><li>Show the child how to record additions up to 10.</li><li>Provide controlled exercises for teaching number bonds.</li></ul>
