This activity was originally created so that my class could get competitive with themselves about improving tables knowledge.
Tables Thing Original
Numbers 1 – 10
Tables Thing Advanced
Numbers 1 – 12 excluding 1 and 10
The way we scored it was that the pupils were given 5 minutes to complete the grid and their score was the number of seconds taken to complete the grid plus the number of blanks and incorrect answers. So a pupil that only filled 84 squares and got 3 wrong would have a score of :
300 seconds allowed + 16 blanks + 3 wrong -= 319
A pupil completing all squares in 275 seconds and making 6 errors would have a score of:
275 seconds used + 6 wrong = 281
This allows pupils to have a number which they can compare to their previous bests and see the improvement they make over time. To do it this way you need to have a countdown clock running so that they can see their time should they finish before the limit.
