Lesson objective: Apply the counting on strategy to add data into an organized data set.

This lesson provides an opportunity for students to apply their knowledge and understanding of counting on to a real-life situation. Students are asked to organize a mixed jar of jellybeans into two jars of a single color and count on to find how many jellybeans are in each jar as a result.

Skills students will use:

• Organizing data into two categories.
• Representing the new data in a picture and table.
• Using the counting on strategy to add to an amount.
• Creating number sentences to model counting on to add.

Students engage in Mathematical Practice 4 (Model with mathematics) as they as they organize and add data, modeling the addition in number sentences.

• count on
• data set
• data table
