Two children were picked to play against each other. They took turns to pick a numbered card and placed the number in a place value column ranging from ones to millions. The aim of the game was to make the biggest number possible. The children soon realised that bigger single digit numbers needed to be placed with the higher place value columns and smaller single digit numbers needed to be placed at the lower place value columns. Once all the cards had been picked, the class read both numbers. The children then played this game in pairs with cards.
