Count by 5s, 10s, and 100s

Skip counting is a valuable skill; scholars practice counting by five, 10, and 100 as they examine these three number sequences. In the first one, learners circle the number that doesn't follow the sequence of adding five. Then, they complete a list of numbers by adding 10 to each, writing in five numbers. Finally, pupils complete one number in a sequence by adding 100. Project this as an all-class warm up, reviewing together once the class has tried it on their own. What other numbers can they count by?
