#To develop an understanding that quantity is something we associate with objects and there are different ways of representing this and that different objects have different measures of quantity
#Represent quantity as numbers and express symbolically
#Understand the difference between the ordinal value of a number and the representation of a quantity

==Developmental Questions (What discussion questions)==
===For initial activity===
*How can you describe the two groups? [ Words – red, large, small, more, less]
*How can you describe the two groups? [ Words – red, large, small, more, less]
*Which words are being used first – more or less, dozen, kilo
*Which words are being used first – more or less, dozen, kilo
*Can these numbers represent only apples or anything else? Does this number “2” mean the same thing when I am counting dogs or notebooks?
*Can these numbers represent only apples or anything else? Does this number “2” mean the same thing when I am counting dogs or notebooks?
*Manipulating the quantities. By physically combining and representing them in numbers, introduce the idea of mathematical operations of addition and subtraction
*Manipulating the quantities. By physically combining and representing them in numbers, introduce the idea of mathematical operations of addition and subtraction
===For Part 1===
*Bring the two groups of apples together. Add Group 1 to Group 2. Describe what happens [ Words – more, large, big, add]<br>
*Bring the two groups of apples together. Add Group 1 to Group 2. Describe what happens [ Words – more, large, big, add]<br>
*What did this process do? I had two groups and I mixed them? What happened?<br>
*What did this process do? I had two groups and I mixed them? What happened?<br>
Separate the two groups again. Can I add only all of them together? Or can I add 1 at a time, 2 at a time, 3 at a time?

The ideas to be introduced would be Skip counting and quantity increase is continuous.<br>

===For Part 2===
*Now from the large group take away some apples. What happens to the number? What have we done?<br>

*Pose this question like this – “ I added 5 apples to six apples to make it 11 apples. What should I do to a bag of 11 apples to make it have 6 apples again”. I take away 5. This is called subtraction and is the inverse process of addition.<br>

==Evaluation (Questions for assessment of the child)==
*Create situations where children work in groups and compare collections of items without counting.<br>
*Create situations where children work in groups and compare collections of items without counting.<br>
*Have groups work with 3 groups of fruits, sticks, pencils, etc. The idea that addition can be extended indefinitely can be discussed.<br>

*In their community, street, what is their house number? What does this number mean?

*How will you count mustard, sand, apples and sugar? The children will discuss this in groups and discuss with the class

===Worksheets===
*Worksheets of simple problem solving – with word descriptions. Children can either draw these answers or write them in statements. Evaluate the ability of the child to process written instructions.
