2 Cluster 3 Lessons
In this lesson, the students are analyzing arrangements of shapes and identifying whether or not they are arranged in an array. This lesson needs to be after the students have already learned the vocabulary associated with arrays and have worked with arrays.
In this lesson students explore arrays through the context of flats of flowers. Students determine the total number of flowers and write an equation using equal addends. Students calculate the total cost of flats of flowers within 99¢ and represent cost with variations of quarters, dimes, nickels, and pennies.
In this lesson students solve a problem where skip counting by 5s and 10s is required to solve a real world problem. Students have some previous practice with skip counting to numbers beyond 100.
In this lesson, students will write a survey question, collect data, and explore ways to display data leading to a discussion of the purpose of bar graphs. The second portion of this lesson supports the students’ use of a bar graph. This lesson may take more than one day.
