A Cylinder Workshop
Students work with given formulas to solve for specific variables. The calculation of the volume of a cylinder and the change in volume when there is a constant surface area is analyzed in this lesson.
Curated OER
The Circumference and Diameter of a Circle
Ninth graders investigate the finding of the diameter of a circle in order to extend the practice towards finding the circumference. They differentiate between the distance measured across a circle from that of around the perimeter.
Curated OER
Construct Figures to Find Specific Volume
Sixth graders use number cubes to explore volume of two-dimensional shapes. They roll a die and construct a shape using the numbers rolled as measurements of the sides. They estimate the volume of a given object, and then use the...
Curated OER
Finding the Area Under A Curve with Random Probability
Students explore the concept of area under a curve. For this area under a curve lesson, students find the area under a curve using the Monte Carlo method using random points and probability. Students calculate the area under the same...
Curated OER
NetsS.A. of Prisms
Students build nets of three-dimensional prisms based on the dimensions they are given for hexagonal prism, triangular prism, rectangular prism. Working in groups, they use their prisms and calculate the Surface Area and Lateral Area.
Curated OER
Cylinder: Student Worksheet
In this cylinder worksheet, young scholars compare three different cylinders to experiment which one has the greatest volume. Students interact with rectangles as they experiment with the cylinders.
Curated OER
How Close Is Our Estimate?
Fifth graders estimate perimeter, area, and volume. They measure perimeter and area using nonstandard units of measurement. Students add and subtract non-standard units of measurement. They add mixed numbers and simplify the sum.

Telling Time to 5 Minutes
In this second grade lesson your class will practice telling time. The goal is to tell time to five minutes using an analog clock. Your young students count by 5 minute intervals and discuss elapsed time.
Improving Measurement and Geometry in Elementary Schools
The Sum of the Interior Angles of a Polygon
Junior geometers discover that polygons can be decomposed into triangles and that the number of triangles can be determined by a rule. Note that the Geometer’s Sketchpad® software is required to carry out all components of this...
Curated OER
Volume of Rectangular Prisms
Introduce the procedure needed to find the volume of a rectangular prism. Learners rank various prisms such as cereal boxes and tissue boxes from smallest to largest volume. They use an applet to find the volume and surface area of each...

Money in Action
Students become familiar with the various coins in our money system as well as amount of each coin. They help develop their ability to count change and find different ways to show equal amounts.
Curated OER
Triangles
This unit enables scholars to apply the rule for area of a triangle (area equals half base times height). They practice multiplication and division strategies as they calculate areas.
Curated OER
Area of Polygons
Students engage in a lesson that is about the concept of polygons and focuses upon finding the area. They use formulas provided in the lesson in order to solve problems given by the teacher for independent practice. Geometric figures are...

Finding Circumference and Area of a Circle
Young geometers explore the concept of circumference and area of circles. They discuss what information is needed to find circumference and area. The resource employs several instructional methods: Frayer Model for Vocabulary, literature...
Curated OER
Peter's String
Students are introduced to the math problem and consider how they could approach it. In pairs, students investigate Peter's conjecture in any way they see fit. They then share their answers with the class.
Curated OER
Karen's Tiles
Students investigate how perimeter changes as area changes to see the relation between area and perimeter for similar shapes. They then students answer the question if the area of the rectangle increase, does its perimeter have to increase?
Curated OER
Calculate It
Fourth graders find the area and perimeters of squares and rectangles using a calculator to check their multiplication. They use the appropriate formulas to find the area and perimeter of the given geometric shapes.
Curated OER
Word Problems: Geometry
Students solve word problems by using basic geometry. In this geometry lesson, students use geometric formulas to find the perimeter, area, and volume of objects. Students complete a worksheet.
Curated OER
Areas of triangles, trapezoids, and rhombi
Students solve geometry problems. In this area and perimeter lesson, students use formulas to solve problems from the textbook.
Curated OER
Making Rectangles
Students study rectangles. In this math instructional activity, students use numbers, measurements and geometry to draw rectangles of varying sizes.
Curated OER
The Chicken Run
Fourth graders work in a group of 4 to make rectangle with a 12m length of string. They discuss its perimeter and how they would calculate its area. Then another group of 4 make another rectangle and estimate if the area would be greater...
Curated OER
New Pen at the Zoo
Students create two drawings for a new animal pen design at the zoo. They must draw the ideas keeping the amount of material available in mind. They compare and contrast their two designs and write how they are similar in perimeter and...
