Direct Instruction

Align ones below ones, tens below tens and hundreds below hundreds. Add starting at the ones place and regroup when a place totals 10 or more.

Worked example: 376 + 458. Ones: 6+8=14, write 4 and carry 1 ten. Tens: 7+5+1=13, write 3 and carry 1 hundred. Hundreds: 3+4+1=8. Result: 834.

Check: 376 is about 400 and 458 about 500, so 834 is reasonable near 900. Estimation does not replace exact calculation.
