Fourth graders explore triangles. In this math lesson, 4th graders discuss the different types of triangles. Students create triangles using wiki sticks. Students complete an online matching game.

Students calculate the midpoint of a line. In this geometry lesson, students identify the different parts of the coordinate plane. They use the midpoint formula to find the middle of segments between a pair of coordinates.

Play a coordinates game to encourage collaborative learning and grid use! Learners plot points on grids and play a game that challenges them to locate a specific point on a coordinate grid by using horizontal and vertical movements.

A geometry game that resembles Battleship is the foundation for hide and seek where "hiders" draw shapes on coordinate planes and "seekers" must guess the shape and its location based on questions and clues. Reproducible, paper-sized...

Shape shifters recognize characteristics of polygons. Embracing language arts skills in addition to math, they use a thesaurus to pinpoint specific attributes of a set of polygons. They also participate in a 21-question guessing game...

Fourth graders investigate regular polygons. In this regular polygon instructional activity, 4th graders explore the attributes of different polygons. Students work in groups to complete a KWL chart regarding polygons.

Students investigate transformation on a coordinate plane. In this geometry lesson, students identify pairs of coordinates and their location on the grid. They perform rotation and reflection of each polygon.

Third graders become more familiar with various geometric shapes by completing the games and activities in this instructional activity. They keep track of the number of each shape they use in each of the three ways.

Learners explore geometry by participating in a pattern identification activity. In this tetrominoes lesson, students define the characteristics of congruent and symmetrical shapes. Learners practice translating shapes across quadrants...

Learners identify and categorize different polygons. In this polygons lesson plan, students research and identify properties of polygons,  identify different polygon shapes, and categorize different triangles and quadrilaterals.

Patterns emerge as the class works together to fill in a number grid. This whole group activity is designed to make all learners feel successful, and ultimately turns into a instructional activity on the least common multiple.

Students use the Internet to answer lab questions about fractals, and then construct fractals using the initial stage and iteration rule. They complete tables and generate rules for the "nth" term and create their own fractals.

Students explore the concept of geometric shapes. In this geometric shape lesson plan, students play bingo to review geometric shapes. Students identify the shape being described by the teacher and put a marker on their bingo card.

Learners introduced to different views of the Earth. They play BINGO with boards that are made of images of Earth.
