In this math game, students will explore the concept of covering a region with unit squares and score points for each correct response. Once they complete the round they can advance to the next level where they will multiply the length measurements to find the area of a rectangular region.

Images of rectangle on coordinate plane, one with easily identifiable area, other image with same rectangle rotated. Distance formula shown to calculate same area.

Students can learn to visualize the effects of multiplying a fixed positive number by positive numbers greater than 1 and less than 1 with this tool. Using interactive figures, students can investigate how changing the height of a rectangle with a fixed width changes its area. e-Math Investigations are selected e-examples from the electronic version of the Principles and Standards of School Mathematics (PSSM). The e-examples are part of the electronic version of the PSSM document. Given their interactive nature and focused discussion tied to the PSSM document, the e-examples are natural companions to the i-Math investigations.

In this assessment task the student will determine the length and height of a shape on a flashcard. They will be asked to use comparing words such as longer or shorter to tell about length of two rectangles. They will also be asked to use comparing words such as taller or shorter to tell about the height of two cans or cylinders. The 2 flashcards along with directions, a recording sheet and rubric are provided.

In this lesson plan, students are tasked with designing a playground at their school. Each section has its own requirement for each quadrilateral. In the end, they must be able to defend their shape against a classmate's of why they choose the shape. They must also list any other quadrilateral that could be drawn in that space.

An interactive applet and associated web page that show the definition and properties of a rectangle in coordinate geometry. The applet has a rectangle with draggable vertices. As the user re-sizes the rectangle the applet continuously recalculates its width, height and diagonals from the vertex coordinates. Rectangle can be rotated on the plane to show the more complex cases. The grid, coordinates and calculations can be turned on and off for class problem solving. The applet can be printed in the state it appears on the screen to make handouts. The web page has a full definition of a rectangle when the coordinates of the points defining it are known, and has links to other pages relating to coordinate geometry. Applet can be enlarged to full screen size for use with a classroom projector.

This resource is from Tools4NCTeachers.In this lesson, students explore attributes of polygons in order to create 2D shapes using given attributes.  Students need some basic background knowledge of the attributes of polygons, including angles, sides, vertices, and right angles.  Remix this lesson to include sample student work... Sharing is caring :)

In this lesson, students will create and name given shapes. They will use precise mathematical vocabulary describe shapes to partner with enough details for the partner to recreate it accurately.

This resource is part of Tools4NCTeachers.This packet contains exit tickets for the First Grade stnanard G.3 (partitioning shapes). Exit tickets are written responses to questions posed at the end of a lesson. They are brief assessments which allow the teacher to determine student understanding of the concepts and skills taught that day. 

This resource is from Tools4NCTeachers. This file contains sample anchor charts to create with students. Anchor charts are to be made with students, then displayed as a classroom reference. Parents may also benefit from seeing anchor charts, as they provide a snapshot into the math class.Remix this resource to include pictures of your own anchor charts.

This lesson is from Tools for NC Teachers. In this lesson, students will design a dog pen using grid paper and square tiles to develop concepts about fixed perimeter and varying areas. This is remixable.

This resource is from Tools4NCTeachers.  In this lesson students are introduced to the vocabulary associated with partitioning shapes into equal shares. Students will also explore shapes that are partitioned into halves, thirds, and fourths. Student recording sheets and pictures of anchor charts are included within this lesson.

This lesson calls for students to compose congruent hexagons using smaller pattern block pieces. They will explain which arrangements of pattern block pieces compose a congruent hexagon, and count the number of smaller pieces that compose the "bigger" shape.

This is lesson one in a series of six lessons focused around developing a mathematical community at the beginning of the school year. The primary goal of this lesson is for students to begin establishing norms for math class. A secondary goal is to start exploring a non-standard problem that has more than one possible solution.
