Understanding number sequences is the basis for algebra studies. Here you will find our worksheets and resources designed to help your child identify a number sequence and fill in missing numbers in a sequence by counting up and down by 1s, 2s, 5s, 10s, and 100s up to 1000. Counting is a great way to help you learn multiplication facts when you repeatedly add on the same number. Counting is also a prerequisite for learning how to add and subtract mentally.
