Twenty cardsThis ITP create stacks of numbered cards and individual cards. Cards appear face down. They can be moved around the screen with or without the help of a hidden grid, 'turned over' to display the card's number and deleted. Cards can be sequenced or generated as a random set, to include whole numbers, decimals or fractions. 
Run Twenty cards 1.1 

The ITP can be used to display sets of different numbers that children can compare and order. The stacks created can support work on identifying, describing, extending and generating sequences. Different stacks can be used to display and reorganise particular numbers from which children can hypothesise and go on to explore properties and patterns in numbers.
