Use this fun 'search and find' resource to practice recognising missing numbers in a sequence on a hundreds board. This is an excellent skill for students to practise as it helps boost fluency and knowledge of numbers. Students are asked to look over the hundreds chart and identify the 10 missing numbers, hidden by different coloured magnifying glasses. There are 6 game boards to choose from. You might also be interested in the digital version of this activity - allowing you to choose the numbers to cover. Why not have the students create a game board for their classmates to play?
