Lesson objective: Apply knowledge of organizing objects into equal groups to create arrays.
This lesson provides an opportunity for students to apply their knowledge and understanding of arrays to a reallife situation. Students are asked to help a character determine whether or not she has enough tickets for herself and her two friends to each ride two carnival rides.
Key Concept students will use:

A group of objects can be organized in an array and thought of as a number of equal groups.
Skills students will use:
 Students may add to find the total and naturally point out a connection to skipcounting. (Grade 2, Unit 8)
Students engage in Mathematical Practice 7 (Look for and make use of structure). As they compose arrays they recognize that the array structure is a collection of rows and columns and that it can be seen as a unit.
Key vocabulary:
 array
 columns
 equal
 organize
 rows
 share
 skip count
