==Substraction with Small Number Rods==
=== Age ===
3-6
 
=== Materials ===
<ol><li>Two sets of Small Number Rods.</li><li>Plain squared paper and a pencil.</li><li>Subtraction Sign Card (optional).</li></ol>
 
=== Preparation ===

 
=== Presentation ===
<ol><li>Directress invites the child to build two stairs with the number rods.</li><li>The Directress selects a rod from the right stair, says a 4 rod. Then she asks the child to select a rod shorter than 4 rod from the left stair. The child selects 2 rod and places it besides 4 rod.</li><li>The Directress invites the child to count together, "1, 2, 3, ... 6. Four and two makes 6. Let's take away 2 (Directress removes 2 rod). How many left? 1, 2, 3, 4. (count). 6 takes away 2 equals 4"</li><li>Directress then shows the child how to record the statement on plain squared paper, i.e. 6-4=2.</li><li>Directress may go on with the presentation by showing a few more examples.</li></ol>
 
=== Control Of Error ===
The rods themselves act as Control of Error because the quantities are fixed.
 
=== Points Of Interest ===

 
=== Purpose ===
<ul><li>Introduce the child to Subtraction situations with answer (differences) under 10.</li><li>Show the child how to record subtraction questions with answers under 10.</li></ul>
 
=== Variation ===
You may use only 1 set of Rods. For example: 6-4=2. Select 6 rod. Count from the right end 1, 2, 3, 4 and cover those with your fingers. The answer is those left uncovered, which are 2.
