Twelve problems under the heading “Sum It Up!”, each written the tall way with one number above the other and a rule underneath for the answer. The facts run from 6 + 4 up to 8 + 8, taking in 10 + 6 and both 7 + 7 and 9 + 6 along the way. A star border frames the page, with a pencil and an apple tucked into the bottom corners.
Most first graders meet addition written across the page, so the switch to columns throws some of them even when the facts are already known. Getting comfortable with the vertical form now matters, because it is how every two-digit and three-digit problem will arrive from second grade onward. If a child hesitates, point out that it is the same question wearing different clothes.
