What is on the sheet
In every row, the first two numbers make the third using the displayed operation. Fill the empty cell. a ○ b = c · Step 1: + · Step 2: − · Step 3: × Original practice activities, not a standardized test or IQ score. Steps describe the task, not an age or ability grade.
Try one example
In every row, the first two numbers make the third using the displayed operation. Fill the empty cell. 6 + 3 = 9 → 9. Read one problem and its conditions before starting. Work without a timer, and keep the key visible where the task requires it.
Check a difficulty
Use the printed operation within each row. When an input is missing, solve backwards and check the full row. If an answer differs, return to the first step that differs and explain the choice. Change the answer after checking rather than guessing a new rule.
Choose the next step
a ○ b = c · Step 1: + · Step 2: − · Step 3: × Try the next step when the current method feels manageable. You may repeat a problem, use a paper marker, or stop and return later.
