WALT: Practice the strategies we have learn’t this term.

1. Identify how many tens are in a number.

1. Miss May wants to take room 5 to the movies. She has $300. The movies cost $10 each. She has 26 students. Does she have enough money? How do you know?
2. Room 5 is going on an ANZAC trip. There are 30 students. Each student needs to pay $10. Miss May has $260. Did everyone pay their money? How do you know?

2. Identify how many hundreds are in a number.

Tickets to a Jay Z Concert cost $100. How many tickets can I buy if I have:

1. $3578 = 80
2. $2601 = 26

3.  Use rounding and compensating to solve addition and subtraction problems.

1. 56 + 99 =155
2. 67 + 9=76
3. 98 + 63=161
4. 73 - 19= 66
5. 82 - 29=67

1.Miss May wants to take room 5 to the movies………..does she have enough money?

• yes

How do you know?

• 300 = 30
• 0 = 0
• 0 = 0

• 30 + 0 + 0 = 30 and 30 is a higher number than 26.

2. Room 5 are going on an ANZAC trip.There are 30 students.Miss May only has $260.

Does she have enough?no

how do you know that?

200 = 20

60 = 6

0 = 0

so 20 + 6 + 0 = 26 and she needs 30.
