Step 1: To make it fun for the kids, gather all your students in a group. Now introduce the concept of More or increase by using students as “counters” to solve.
For example, to model 3 + 2, have three students stand in a group and have two more join them. Then have everyone count the students to find the sum.
Step 2: Repeat this activity with other items like blocks or toys so that children are able to understand the process.
For Example– i) Take blocks of two colors and put them in two baskets.
ii) Basket 1 has 4 blocks and Basket 2 has 3blocks. Make the children count these blocks in both the baskets separately.
iii) Now just mix all the blocks in both the baskets by putting them on a table. Ask the children to count the total number of blocks on the table.
This way repeat this exercise 3-4 times using the blocks with different numbers.
Step3: After 3-4 times of repetition, now make objects like balls , apples fruits etc on the black board and Put them in squares as show in Fig 1.
Now make them count the fruits in two separate boxes.
After that ask them how many ‘total’ fruits are there including apple and oranges.
Do this activity with more objects until its clear to them that how things are getting totaled up or numbers increasing.
We get one more We get one more
=1 apples = 2 apples = 3 apples
Step4: Once you are confident that everyone in the class has understood, then tell the kids, that writing ‘one More’ is taking time taking, so we will now make a small sign or symbol.
Now again repeat the step 3 , but putting the ‘+’ sign.
Step 5: This way as a teacher you are also very clear how things are progressing in the class and where children are unable to grasp the concept.
