Sixty single-digit addition and subtraction facts, with a box at the top of the sheet for the time taken and a score out of sixty. The idea is one minute against the clock, the same drill day after day, and a number that moves - which is why the header records both rather than leaving a bare worksheet.
Every sheet is generated fresh, so yesterday's page cannot be memorised and today's time still means something. Print a week at once with Number of Pages and each page will be different.
A one-minute timed drill on basic facts, done regularly, where the student competes against their own previous time and score rather than against other students. The point is recall speed, not new material.
Sixty is the common size - one per second is the notional target, though few students get there. Change it with Number of Problems Per Page if sixty is discouraging.
Yes. Tick Multiplication above and untick addition and subtraction, or use the Timed Math Drills page and choose the operations you want.
No. Answer pages print with a blank header, so the key does not repeat the name, time and score line.
