In this task, students apply their place value understanding to compose and decompose 2-digit numbers. A scoring rubric is included. The task may be used for instructional or assessment purposes.

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.

This lesson uses the book The Grouchy Ladybug as a context for telling time.

In this lesson, students compare sets and make equal sets. The lesson should be facilitated at the beginning of a unit on comparing sets once students have been exposed to comparison vocabulary (more, less, greater, fewer).

Lesson may be repeated with amounts closer in range, making it trickier to compare (i.e., 8 & 10).

In this task, students sort animals into categories of their choice, and solve problems related to the categories. The task may be used for instructional or assessment purposes.

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.
