Arithmetic by Colorado University
This is one of the best times tables support activities I have seen in a long time.
The game offers three modes on which pupils are offered the opportunity to Multiply, divide or determine factors.
Three Levels of each of the above are on offer: within 6×6, within 9×9 and within 12×12 making this activity suitable for use across the whole primary age range.
Each activity can be attempted against the clock so giving students the opportunity to improve their times and thus their times tables competence. There is also an option to tur off the sound (thank goodness!).
This activity is tablet friendly and works very well on my elderly iPad (double tap required to select a square in the matrix when on iPad)
