Estimate:

712 + 492 =

• 600 + 400 = 1.000

• 700 + 500 = 1.200

• 700 + 400 = 1.100

• 600 + 500 = 1.100

Estimate:

384 + 296 =

• 400 + 300 = 700

• 300 + 200 = 500

• 400 + 200 = 600

• 300 + 300 = 600

Estimate

716 - 382 =

• 700 + 400 = 1.100

• 600 - 400 = 200

• 700 - 400 = 300

• 700 + 300 = 1.100

Estimate

982 - 296 =

• 900 - 300 = 600

• 1000 - 200 = 800

• 1000 - 300 = 700

• 900 - 200 = 700
