__Math Module__

__Math curriculum – Elementary stage__** (Grades 1-3)**

An important goal of math module in an elementary stage is to eliminate the fear of math and dealing with numbers that are found in so many children. The module is designed to not only make children skilled in basic arithmetic operations but also feel comfortable in handling numbers and their application in real life.

The math module attempts to help children use numbers not only to count but also see the relationship among numbers as elements of an ordered set. While understanding, for example, that 4 is smaller than 5 by one and larger than 2 by 2, or that it comes in between 3 and 5, the essentials of addition or subtraction are introduced/ internalized. The children are taught to not only perform basic arithmetic operations, but also use alternate counting/ computational technique/ algorithms, and to cross-check the answer. They begin to understand the relationship among different operations, e.g. that the addition and subtraction are opposite; multiplication is repetitive addition, and the division is repetitive subtraction. Special emphasis is placed on understanding the place value, how it is used to represent larger numbers, and how this is operationalized in various standard procedures used in mathematical computations.

The sequencing of lessons, time devoted to each section/ stage, teaching guidelines, sequencing and composition of worksheets are all important elements in achieving above objectives. The worksheets and activities are so designed that besides getting adequate repeat practice, the children learn to substitute the lazy habit of pattern formation with exact computations. Exercises are set out in a way that requires children to examine alternative hypotheses before choosing the correct one and to find pattern under a jumbled set. Children are enabled to estimate the size of a set of objects, with the numbering scheme providing an exact measure of the estimate. Similarly, children are enabled to convert problems/ questions in daily life into questions involving arithmetic operations.

Examples of pedagogical approach employed are as follows:

1) Counting by using objects: The child is to pick up a number card and the correct number of counters according to the number spoken by the teacher. The child is also asked to add or reduce one counter from the set and choose corresponding number card.

2) Shopkeepers and Buyers: Children are formed in pairs. One is to act as the shopkeepers and other buyers. Byers give number card to the shopkeepers and shopkeepers give the correct number of counters to the buyers.

3) Which number is after and before me: Speak a number and ask the child to show a number card either after/ before number of that number and put the correct number of counters or Ask the child to pick up number card and put correct counters accordingly to the number spoken by the teacher. Ask them to find either after/ before number of that number and put correct number card.

4) How I can make: Ask the child to put the correct number of counters accordingly to the number spoken by the teacher. The teacher speaks a number that is + or – 3 of that number. Ask the child to pick up that number card and ask them to make this number using the correct number of counters

5) Sort and Count different object and link with number card: Ask the child to sort and count the different objects kept on a box and match it with the number card

6) Sequencing: Ask children to speak numerals in different sequences ex. 1,2……,10 or 1,3,5…9 or 2,4,6……10 . The child who will make mistake will be out.

7) Comparing any two number using objects: Ask the child to pick up two number cards and put correct counters accordingly to the numbers spoken by the teacher. Ask them to find out smaller and larger sets through one to one correspondence. Ask to find out how many less in smaller sets than larger sets and the same way how many more in larger sets than a smaller set.

8) Which number is a smaller / larger number than me: Ask the child to pick up number card according to the number spoken by the teacher. Ask them to find smaller/ larger number to that number.

9) Comparing the greatest and smallest number using objects: Ask the child to pick up four number cards and put correct counters accordingly to the numbers spoken by the teacher. Ask them to find out greatest and least number through one to one correspondence.

10) Arrange numbers in ascending and descending order: Ask the child to pick up four number cards and put correct counters accordingly to the numbers spoken by the teacher. Ask them to arrange numbers in ascending or descending order through one to one correspondence.

11) Understand Zero using counters: Ask the child to pick up number card and put correct counters accordingly to the number spoken by the teacher. Ask them to reduce counters accordingly to the number spoken by the teacher. This will be repeated till no counters will be left with children and ask them to show the correct number card.

12) Understand Zero using counters: Ask the child to pick up number card and put correct counters accordingly to the number spoken by the teacher. Ask them to reduce the same number of counters all together and ask them to show the correct number card.

13) Counting using fingers/ finger cuts: Ask the child to pick up number card and show the correct number of fingers/ finger cuts according to the number spoken by the teacher.

Understand Place value:

14) Grouping into units and tens: Ask the child to pick up number card and put the correct number of tens of bundles and loose counters accordingly to the number spoken by the teacher. Add or reduce one counter from it and put the correct number.

15) Dice game:

A (Using single dice): Ask the child to throw the die and collect from the box a number of counters corresponding to the numeral thrown. As soon as a child has collected 10 counters he can exchange them for a bundle of ten. The winner is the first child to collect maximum bundles.

B (Using tens and unit dice): Ask the child to throw two dies and collect from the box a bundle of tens and counters corresponding to the numeral thrown.

16) Secret number using arrays: Teacher will decide a number. Child locates the secret number first by its tens digit, then by its units digit referring to their arrays while making their guesses.

Addition and Subtraction:

17) Add or Subtract using counters: Ask the child to pick up number card and put correct counters accordingly to the number spoken by the teacher. Ask the child to pick up another number card and add/ reduce correct counters accordingly to the second number spoken by the teacher. Show number sentence using number card and symbol card.

18) Add or Subtract using number line: Ask the child to pick up number card and go ahead on number line accordingly to the number spoken by the teacher. Ask the child to pick up another number card spoken by the teacher. and go forward or backward on the number line depending on the operation involved. Show number sentence using number card and symbol card

19) Add or Subtract using fingers/ finger cuts: Ask the child to pick up number card and count fingers / finger cuts accordingly to the number spoken by the teacher. Ask the child to pick up another number card and add/ reduce finger/ finger cuts accordingly to the second number spoken by the teacher. Show number sentence using number card and symbol card.

20) Dice game: Ask the child to make a grid in a book with a number up to 10. Each child throws the die twice and can either add or subtract these two numbers using counters and then they have to cut the resulting number in their grid. The first child to cut the maximum grid is the winner.

21) Guess how many: Teacher puts counters and children will count. She asks them to close their eyes and removes some counters and hides them in her closed hand. Then they open their eyes and look at the remainder and find how many counters the teacher is hiding in her hand. Then again count the counters together to verify. Write number sentence on the blackboard. This will continue for all possible pairing of a given number.

22) Addition and Subtraction in daily life: Teacher puts counters and child will count It. She asks them to close their eyes and add/ removes some counters. Then they open their eyes and look at the counters and decide which operation involved. Ask them to show number sentence using number card and symbol card. Ask them to make a word problem using number sentence.

Multiplication :

23) Equal grouping: Distribute the counters equally and found out how many counters in a single group and how many groups made.

24) Multiplication as repeated addition
