Why Lesson Planet?
Students can practice counting by threes in this fun coloring activity. By coloring every third numbers, students can not only reinforce their knowledge of counting by threes but can also practice their pattern-making. The worksheet then asks students to describe the pattern that the student has completed. The activity includes two pages - one page has a 6x6 pattern and the next has a 7x7 pattern - and an answer key for both patterns.
