Are you searching for a purpose for geometric constructions? Use an engaging approach to explore dilations. Scholars create dilations using a construction method of their choice. As they build their constructed dilation, they...

Playing with mathematics can invoke curiosity and excitement. As pupils construct triangles with given criteria, they determine the necessary requirements to support similarity. After determining the criteria, they practice...

A diameter is the longest chord possible, but that's not the only relationship between chords and diameters! Young geometry pupils construct perpendicular bisectors of chords to develop a conjecture about the relationships between chords...

You know about the tangent function, but what are tangent lines to a circle? Learners investigate properties of tangents through constructions. They determine that tangents are perpendicular to the radius at the point of tangency,...

How do you prepare class members for the analytical thinking they will need in the real world? An assessment requires the higher order thinking they need to be successful. The module focuses on the concept of rigid transformations...

Learners will have fun creating a parachute to collect data with. They will construct the parachute in small groups, measure the materials, and create an observation sheet. Then they drop the parachute and make predictions about how long...

Symmetry, line, shape, art, and math are all connected through a fun hands-on craft. Included are instructions to a classic activity, where learners create butterflies to show symmetry in nature and then discuss symmetry in math. It is...

Your learners find and construct the line of reflection between a triangle's pre-image and its reflection image in this short activity.

A series of geometry worksheets have mathematicians constructing, dissecting, overlapping, and measuring as they analyze angles in various contexts. Learners use symmetry and reflections in a compass rose to write instructions on...

Your geometry learners will discover and show the construction of the circumcenter of a triangle. Guided by the steps in the activity, they construct perpendicular bisectors of each side that have a point of concurrency called the...

Youngsters count, classify, and estimate quantities using buttons after a read aloud of The Button Box by Margarette S. Reid. They discuss the difference between guessing and estimating. Based on an experiment, they predict the...

An engaging lesson which has elementary learners measure weight to the nearest pound and construct and interpret a bar graph! They measure length using non-standard units and determine area using square tiles. Pupils round their birth...

Build an interest and appreciation for architecture in your young learners with this fun 10-lesson art unit. Engaging children in using their five senses, the class first observes the environment around them, paying...

This activity is a follow-on activity to inscribing a square in a circle. The overall problem is more complex. It deals with geometric constructions, properties of triangles, and regular hexagons. The final part of the activity...

For kids who love movies, figuring out a schedule for the maximum number that can be seen in one day is not only a good demonstration of Common Core mathematical practices, but also a highly motivating activity. Robert Kaplinsky...

Learn about patterns in residual plots with an informative math lesson. Two examples make connections between the appearance of a residual plot and whether a linear model is the best model apparent. The problem set and exit ticket...

Our teacher told us the formula had one-third, but why? Using manipulatives, classmates try to explain the volume formula for a pyramid. After constructing a cube with six congruent pyramids, pupils use scaling principles from...

Learners construct a model of an electromagnetic spectrum using play-doh and string. They use exponents and plot the radio/microwave, infrared, and visible bandwidths of the spectrum.

Your geometry learners are guided by questions that help them use the language of reflections to explain the Side-Angle-Side congruence between two triangles in this collaborative task. Given a sample solution, declaring the...

Why are only four colors needed to color webs from regular pentagons, not five? An assessment task requires young mathematicians to first construct regular pentagons using a compass and straightedge, then has them consider a shape...

Engage in a hands-on addition and subtraction activity that is a wonderful tie-in with ocean studies. As the teacher, you will make up equations using construction paper and goldfish crackers.

Gardening geometers construct the formula for the area of a rectangle by viewing a video revolving around two young people, their lawn mowing business, and their need to charge by the square meter. A relevant real-life application lesson!

Young scholars explore the concept of probability. They calculate the probability of an event happening and graph their results. Students determine the probability of winning a sweepstakes. They construct a bar graph to represent all the...

Sixth and seventh graders construct a "metric machine" as a kinesthetic aide in converting from one unit to another in grams, liters, or meters. They complete a metric activity on the Internet and view about five minutes of a video on...
