As learners become familiar with counting, it's helpful to use worksheets like this one to focus on just a few numbers at a time. Scholars begin by tracing the numbers 17 and 18, then print each numeral once on their own. Next, they count sets of birds and match them to their value (17 or 18), being sure to count carefully to keep track. Consider having them number each bird as they go for extra practice. Finally, there is a number sequence that is missing these two digits, and learners add them in to complete it.
