What's on this sheet

The whole difficulty of decimal addition is place value — 0.4 and 0.04 look alike but are ten times apart, so the points must sit in one column. Our sheets print in a vertical form that stacks the points for you, or a horizontal form once a child is ready to keep track alone. You choose tenths or hundredths, and every pair uses the same number of places so the columns stay honest.

Why this sheet works

Answers are computed exactly, never as rounded floating-point, so 0.1 + 0.2 is always 0.3 on the key.
