Counting Caterpillars

These caterpillars make great learning buddies! Each one has a series of numbers in the “decades” (all even groups of tens). Students fill in the missing number. There are no numbers over 100. The caterpillars walking to the left are series of numbers increasing with each step. Beware, though – the caterpillars walking to the right start with a larger number and decrease with each step! You’ll have your kids counting forward and back by tens in no time with this cute worksheet!
