First graders create two-dimensional shapes. In this shapes lesson, 1st graders learn about different two-dimensional shapes. Students have many hands-on experiences with these shapes including the use of geoboards, shaving cream, yarn,...

Students reinforce geometric concepts by playing "Guess My Solid." Through a process of elimination, they determine the shapes of mystery solids. Finally, students use various materials to construct their own geometric figures.

Learners determine the number of pennies needed to fill a room.  In this pennies lesson plan, learners work in groups to determine the number of pennies needed to fill a room.  They compute the probability of the head of a pin...

Learners explore pyramids. In this math lesson plan, students discuss where they have seen examples of pyramids. Learners classify pyramids as three-dimensional figures and identify their attributes.

Fifth graders explore polygons. For this math lesson, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

Students investigate geometric shapes by creating figures on a plane. In this polygon lesson, students complete a worksheet based on the angles in a power polygon. Students identify the different types of polygons and define their...

Fifth graders create a reflection of a poygon using a Mira. They discover that a line connecting a vertiex of a polygon and the corresponding vertex of its reflection is perpendicular to the line of reflection. Students create a glide...

Students identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...

Geometry adventurers study circumference of a circle as they listen to Sir Circumference and the Dragon Pi, by Cindy Neuschwander. In groups, they use string to measure the diameter and circumference of circular objects and...

Learners discuss the appropriateness of using a specific tool to measure and define an object. After measuring the area of their classroom and the objects in it with the appropriate tools, they create a floor plan that makes the most...

Students use geometry or trigonometry to measure the distance of a far off point. They verify their measurements using a tape measure to check their work.

Second graders gain an understanding of geometric shapes and spatial reasoning. They learn the attributes of solid shapes in everyday activities. Students compare geometric shapes to everday objects, finding things that serve a purpose...

Students examine how to investigate polygons using an instrument of their own construction. They should be able to prove the general formula for the number of degrees in any polygon (including a triangle). Finally they investigate an...

Investigate the application of vector transformations applied to linear systems. Individuals use vectors to transform a linear system translating the solution to the origin. They apply their understanding of vectors, matrices,...

Fourth graders investigate congruent shapes. In this congruency lesson, 4th graders explore examples of congruent shapes. Students determine how to check for congruency by sliding or flipping the shape.

Pupils describe, make and compare polygons. In this creating polygons lesson, students identify properties of quadrilaterals and describe common features of two dimensional shapes.

Learners find out the meaning for prefixes used in math vocabulary. By dissecting words used in everyday math, they figure out what the prefix indicates and what the word means. A variety of well-organized worksheets and activities...

Most problems can be solved using more than one method. A worksheet includes just nine questions but many more ways to solve each. Scholars must graph, solve, and justify quadratic problems.

Young mathematicians explore the maximun area for patio with the added complexity of finding the mimimum cost for construction. First, they maximize the area of a yard given a limited amount of fence and  plot width v. area on a...

Scholars find a pattern from a geometric sequence and write the formula for extending it. The activity includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

Functions require an input in order to get an output, which explains why the answer always has at least two parts. After only three multi-part questions, the teacher can analyze pupils' strengths and weaknesses when it comes to...

Students investigate the movements of the planet Pluto. Students participate in a hands-on activity to record data similar to the movements of the planet Pluto. Students compare their data to that found on a website.

In this famous person worksheet, students answer 10 multiple choice questions about the life and times of Albert Einstein. They answer questions about his childhood, first jobs and scientific theories.
