Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.


General Information

Subject Area: Mathematics
Grade: 2
Domain-Subdomain: Geometry
Cluster: Reason with shapes and their attributes. (Additional Cluster) -

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.

Formative Assessments

Name Description
Complete the Rectangle

Students are given a rectangle with one column and one row of unit squares (same size squares) drawn. Students are asked to complete and then find the total number of same size squares in the partition.

How Many Units?

Students are given a rectangle with some columns and rows partially constructed. Students are asked to find how many same-size squares are in the rectangle.

Construct Rows and Columns

Students are given a rectangle with tick marks drawn horizontally on one side of the rectangle and vertically on the bottom of the rectangle. Students are asked to partition the rectangle into columns and rows and then determine how many unit squares (same-size squares) are in the rectangle.

Partition the Rectangle Into Unit Squares

Students are given a rectangle with one unit square (same size square) drawn in the corner of the rectangle. Students are asked to draw the remaining unit squares and then find the total number of unit squares in the rectangle.

Lesson Plans

Name Description
Partition the Flag

In this Math and Social Studies Civics lesson plan, students will use their mathematical knowledge of fractions as equal groups, and knowledge of wholes, and fourths. Additionally, students will use two interrelated symbols representing Florida, to design a new Florida State Flag into four equal parts. Students will discuss and reason why Marjory Stoneman Douglas and the Florida Everglades were chosen as symbols of Florida, and brainstorm other possible symbols that could be used based on their personal experiences. As students design their flag, they will determine the best way to partition the rectangular shape into fourths, so that the four areas are equal-sized parts.

Chocolate Pieces

Students will learn how to partition a rectangle while actively engaged. Students will be working with post-it notes and a Chocolate Bar worksheet. By the end of this lesson, students will be able to identify and explain the difference between a row and a column. They will also be able to count the total number of squares that make up the rectangle.

Rectangles Rule! (Lesson 1 of 2)

In this lesson students will use rulers to measure the side lengths of rectangles and use 1-inch square tiles to cover the rectangles. Students will count the total number of square units to find the area and explore relationships between the lengths of the sides and the total number of tiles.  In # 66132 Rectangles Rule! Team Challenge (Lesson 2 of 2), students will expand their understanding of tiling to find area to connect area to a multiplication formula.

Rectangles Rule! Team Challenge (Lesson 2 of 2)

This guided inquiry lesson is designed to follow another CPALMS published lesson #63297 Rectangles Rule! In that first lesson, students used a ruler to measure the side lengths of rectangles and used 1-inch square tiles to find the area of the rectangle. In this lesson, students will use the inquiry process to problem-solve a team challenge: Partition a rectangle into same-size squares using a ruler and determine a formula for finding area (area = length x width). Students will brainstorm, investigate, and share their solutions on how their team worked together to find a solution to the challenge. 

Which Rectangle is Bigger?

Students will learn how to partition rectangles into equal parts and write equations to represent the parts. They will gain a basic understanding of area from the book Bigger, Better, BEST! by Stuart J. Murphy.
