Construct yourself a winning geometry unit. A set of lessons introduces geometry scholars to constructions and proofs with compasses and straightedges. It also covers triangle congruence through transformations. This is the second of...

Learn about constructing figures, proofs, and transformations. The seventh unit in a course of nine makes the connections between geometric constructions, congruence, and proofs. Scholars learn to construct special quadrilaterals,...

Show the class the world as they've never seen it before—from way above! Learners try to unravel the mysteries presented by rich satellite imagery, learn to interpret topographic maps, and study erosion by constructing their very...

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

The last unit in the series by Core Knowledge focuses on alternative spellings, nouns, verbs, conjunctions, subject-verb agreement, using commas in a series, constructing sentences, and following the writing process while writing...

Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Young citizens construct an understanding of urban planning in this cross-curricular unit. Covering every aspect of city development from the political, economic, and social influences to sustainable building practices, this...

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Use the parallel lines to find your way. After first reviewing geometric constructions and the relationships between angles formed by parallel lines and a transversal, young mathematicians write proofs for theorems relating to parallel...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Perhaps planning a city isn't so difficult after all. Scholars first perform geometric constructions and investigate how parallel lines are useful in real-world situations. They then work on a city design project, drawing street maps,...

Eighth graders take a stand on a variety of controversial topics with a lesson on argumentative writing. As they view an informative presentation and work with collaborative groups, they decide which side of each argument they want to...

By constructing a watershed model and identifying watershed features in it, they discover how water erosion changes the landscape. As with most watershed modeling activities, this one is costly in terms of time and materials. It is,...
