A fantastic website resource that I've used in KS1 and KS2. It can literally be used however you wish. I&'ve used it to do times tables, number facts, multiples,factors, sums etc. It&';s a lovely plenary, and can be adapted to any maths topic.
A great resource with so many potential uses. Teachers could mark numbers and ask students to identify patterns, or ask children to continue and complete patterns... or even for quickfire games for starters and plenaries. A really useful resource!
