### Use mental math OR rounding to estimate the answers below:

• 643+950+50

• 643+ (1000)= 1,643

• Compatible numbers

OR

2. 600+ 1,000+ 50 = 1, 650

ROUNDING

• 1, 550- 397

• 1,550 – 400 (+3)

1,550-400= 1,150

1,150 – (-3) = 1,150 +3 = 1,153

OR

2. 2,000- 400 = 1,600.

ROUNDING

### Estimate

• 4,785 – 2, 109

• 5,000- 2,000 = 3, 000

• 55.3 + 2.9

• 55 + 3 = 58
