Relations and Graphs
Here is a simple, yet clever lesson on how to teach the important concepts of greater than, less than, and equal to. Pupils write their names down on grid paper - one letter per box. They compare their names and find a name that is...
Fraction Bars
Quotients of Whole Numbers that Equal Fractions
A complete lesson on dividing whole numbers by other whole numbers and getting a fraction result. Groups of learners use fractions bars, and strips of paper that are cut to specific lengths. The hands-on activities in the lesson are...

Tricorn Triangles
Help your learners examine triangles. Pupils explore the different sizes and measurements of triangles. They discover triangles can be isosceles or scalene, and examine the attributes of triangles. Here is the website where you can...
Curated OER
Equivalent Fraction Paper Strips
Young learners compare the relative values of fractions by making physical representations. They fold and label strips of paper that are equal in length to represent "one whole" and the equal parts that fractions represent. Also, they...

Special Lines in Triangles (part 1)
Allow your pupils to become the mathematicians! Individuals explore the properties of a midsegment of a triangle through construction and measurement. Once they figure out the properties, learners use them to draw conclusions.
Curated OER
Ant and Elephant
Have you ever wondered how many ants make up an elephant? Inquisitive minds will be amazed as they use scientific notation to compute and compare the mass of an elephant to an ant. Have participants make guesses and see how close they...
Curated OER
Supplementary, Complementary, and Vertical Angles
By using circles that they cut out and label themselves, learners literally "get a grip" on the angles they identify: supplementary, complementary, and vertical. They solve missing measurements based on properties of supplementary,...

"Polly"gon Pockets
Explore polygons with your elementary learners. Divide the class in 12 to configure the polygon puzzle before them. They list the attributes of each type of polygon they see, and if there's time, they jump on the interactive website...
Curated OER
Similarity and Dilations - Discover Properties of Similar Figures
Learners investigate properties of similar figures. For this properties of similar figures lesson, pupils construct similar figures using Cabri Jr. They dilate their figure to create a similar one, and discuss the relationships between...

Musical Vibes with Palm Pipes
Ancient people used musical pipes as early as the third millennium BCE. Young scientists explore the workings of musical pipes to better understand the relationship with frequency, length of pipe, and sound waves. They determine the...
Curated OER
Angles
Fourth and fifth graders investigate angles and name them according to the criteria for obtuse, acute, and right angles. They examine a human-made yarn pattern on the floor of their classroom and identify angles, vertices, and types of...
Curated OER
Splitting the Penstock
Students investigate the best way to calculate the measurements of an area. In this geometry lesson, students relate a large circle to a cylinder and its measurements. They use PVC pipes to gain hands on experience as they calculate the...
Curated OER
Hunting for "Measured" Treasure
Students compare and order objects according to length. They see that to conserve length, meaning that the length of an object is not altered by a change in its spatial position, even though it may appear to look longer or shorter than...
Curated OER
Time To Measure
Third graders measure time and length. Through the use of video and technology, they explore key elements of measurement, such as units and conversion between units. They explore alternate units of measurement and apply measurement to...

Finding Your Stride Length
Students participate in an estimation activity to determine the length of a hallway or to estimate how many people can fit in the school stadium or gym.
Curated OER
Measuring Natural Objects
Students predict the measurement of objects. In this measurement activity, students estimate the measurements of objects in a lab. Students measure irregular objects and generate scientific observations.
Curated OER
Approximating Measures
Fourth graders complete a worksheet about approximate measurements. In this lesson on approximation, 4th graders compare the wingspan of a given bird to the wingspan of other birds and classroom objects.
