Young scholars solve word problems by using basic geometry. For this geometry lesson, students use geometric formulas to find the perimeter, area, and volume of objects. Young scholars complete a worksheet.

Students study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.

Third graders practice measuring items by examining classroom objects.  In this geometry lesson, 3rd graders utilize measuring tools to find the weight, time, length or temperature of specific classroom items.  Students predict...

First graders explore estimating and measuring distances. They analyze and discuss a map of New York State, make estimations, measure distances using yarn, and calculate total distances between cities on the map.

Most adults remember learning about the Pythagorean theorem, but they don't all remember how to use it. The emphasis here is on developing an intuitive understanding of how and when to use the theorem. Young mathematicians explore...

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

What do you need to prove triangles are similar? Learners answer this question through a construction exploration. Once they establish the criteria, they use the congruence and proportionality properties of similar objects to find...

In this geometry worksheet, 10th graders use the theorems regarding right triangles to find the missing length in a special right triangle. The one page worksheet contains eleven questions. Answers are included.

Is the amount of information getting overwhelming for your geometry classes? Use this strategy as a way to organize information. The resource provides a handout of information studied in relation to triangle congruence. It includes a...

Tenth graders investigate the history of Pi and how it relates to circles. In this geometry lesson, 10th graders measure the circumference of a circle and the diameter of a circle. They relate these measurements to the number of Pi or 3.14

We know theorems about circles—now what? Class members prove a theorem, with half the class taking the case where a point is inside the circle and half the class taking the case where a point is outside the circle. The lesson then...

Second graders identify the hour and minute hands. They tell time by the hour, nearest quarter hour, half hour, and determine the relationships of time (e.g. minutes in hour, days in a month, weeks in a year). They create over-sized...

In addition to the catchy title, this lesson plan provides upper graders an opportunity to more closely scrutinize the attributes of plane figures. In particular, they focus on the similarity of different shapes. Both whole-class and...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Let your use of the resource be in proportion to its usefulness. Pupils investigate similar triangles by measuring side lengths and considering given angle measures. The results of the investigation help develop generalizations about...

Get your class out in the environment for hands on math activities. In this wetlands lesson, learners transplant native plants, calculate how much soil is needed, and perform math activities based on this experience. They then make...

Boxing takes on a whole new meaning! The second installment of the three-part series has groups create lidless boxes from construction paper that can hold the most rice. After testing out their constructions, they build a new box....

Learners explore the measures of the angles of a triangle in this geometry lesson plan. They use Cabri Jr. to investigate the sum of the measures of the interior angles of a triangle, and examine the relationships between the interior...

Students perform transformations and translations using polygons. In this geometry lesson, students perform transformations on a coordinate plane. They identify the image and pre-image of each figure.

Have fun calculating angles for different polygons. The class differentiate the relationship between the interior and exterior angles of polygons. They discuss linear pair as it related the polygons and their angles. This is done as they...

Second graders make an origami Johnny Appleseed. In this geometry lesson students follow folding instructions. They find different geometric shapes while they are folding. They create Johnny Appleseed's body and attach a face and hands...

In this solar storms instructional activity, students use a diagram given the location of two STEREO spacecraft satellites, a coronal mass ejection, the sun and the Earth to solve 2 problems about the coronal mass ejection. Students use...

In this geometry instructional activity, 10th graders determine the measures of various angle pairs:  supplementary, complementary, and vertical angles.  The two page instructional activity contains a combination of twelve...

Second graders calculate mileage for a journey. In this place value and measurement lesson, 2nd graders read Johnny Appleseed, work in groups to locate his birthplace on a map, locate the other states he stopped in, and measure the...
