Activities

1.Quiz: I have some chocolates with me. I gave 4 chocolates to my sister. I have 17 chocolates left. How many did I have in the beginning? Make an equation.

2. How many pens/ sticks you would need to make alphabet A? How many sticks you would need to make 10 As ? Repeat this rule for alphabets E, H, V, I

3. Play in pairs. One student ask the other to think of a number. Multiply the number by 2, then add 2, multiply 5, then add 5, multiply 10, then add 10. Ask the friend for answer. You can guess what the number is. Trick is ignore the units and ten's place digits. Consider the left digits, subtract 1 and that is the number thought by the student. Make an equation of this game
