In our lesson on comparing numbers, the children played a game to consolidate their knowledge. We began by recapping place value and how it helps us read big numbers. Next, the children took part in a practical activity. Each child wrote a single digit number on their whiteboards. Two children were picked to play against each other. They took turns to pick a child from the class. They placed the child (and their number) in a place value column ranging from ones to tens of 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 children had been picked, the class read both numbers. The children then played this game in pairs with cards.
