This is a two-lesson set for to teach students to explicitly think of counting strategies, and to create an anchor chart to use student-generated strategies later. The first lesson has students explain how they count while the teacher records and guides the discussion. The second lesson uses the Dr. Seuss book "Ten Apples up on Top" to model and practice using a ten frame as a counting strategy.
Each lesson includes 3 differentiates small group lessons that can be used to extend students' learning as a part of your overall math lessons for a week.
The lesson plan also includes 3 variations on of ten frames that you will need for the lesson.
I've taught this lesson 3 times in PreK4, usually in the fall as a part of our unit on health. It could be modified to focus more on strategy development in K, as well.
