In this lesson, the children used their improper fractions and mixed numbers knowledge to play bingo! The children got into mixed ability pairs. They selected 9 mixed numbers from a list of 16. Each time an improper fraction was revealed, the children had to convert the improper fraction to a mixed number and mark it off if they had it. The first pair with all 9 mixed numbers crossed off was the winner! The children then repeated the game but played the opposite way round—picking improper fractions and converting to mixed numbers. We used multi-link during the lesson to help us understand the relationship between improper fractions and mixed numbers.
