Introduction:

Welcome everyone! Today we are going to learn how to add two-digit numbers within 20.

Activity(1):

Let’s practice with some paper and pencil. First, I am going to give you some two digit numbers. Write these two numbers in the two columns and add them.

• 45 + 17

• 62 + 10

• 72 + 3

Activity(2):

Now we will try with a game called ‘Ghost Blasters’. In this game, you need to enter two numbers in the columns and shoot at the target. The game will appear after you click on the ‘launch’ button.
