Remembers which facts you need and skips the ones you know
Short sessions every day work best!
A short quiz with the times tables mixed together that remembers how each fact went. Facts your child finds hard come back sooner, and facts they know come back less often.
Each session mixes facts that are due for review, facts that were answered wrongly or slowly, a few new facts and some known ones to build confidence.
Not unless you turn it on. Timer Mode in My Player gives 6 seconds for each question.
A short session every day is best. 10 questions take about 3 minutes and 20 take about 5. Answers are saved as you go, so stopping early loses nothing.
