Adding 3-digit numbers using compact additionSheet 2

_day2

Challenge

What happens with 4-digit numbers, e.g. 2468 + 8642 = ?

• Write a 3-digit number obeying this rule: ◦ The digits must go up in twos (e.g. 468 or 357).

• Write the number with the same digits in reverse order.

• Add the two numbers using column addition.

• Circle the answer.

• Repeat this four times.

• What do you notice about the pattern in the answers?

• Predict what happens if you add numbers which go up in threes (e.g. 147 and 741).

• Try three like this.

• How about if they go up in 4s….?

Challenge

Use digits 3, 4, 6, 7 to create pairs of numbers to fit this sentence. + = 110. You can only use each digit once per addition. Write two sentences giving the same total using 1, 9, 8, 2.

Use number bonds to help you write the missing numbers.

10 + = 20 + 12 = 20

33 + = 50 + 31 = 50
