I've updated the electronic dice on MathsStarters. Includes ready to go Multo and Addo cards.

Variations of dice include two six-sided dice, two ten-sided dice or two custom dice (0 to 20) - the dice can show multiplication or addition and answers.

I've added an additional game under the *Fractions* category on MathsStarters Bingo:

**Converting fractions, decimals and percentages**

If you're not sure how to use this Bingo game, have a look at this earlier post.
