Free, standards-aligned geometry support designed for Florida teachers and students
Geometry is about more than memorizing formulas. Students need to visualize figures, recognize relationships, test ideas, and explain why their reasoning works.
Khan Academy’s revised Florida B.E.S.T. Geometry course was built specifically for Florida students and aligned to the state’s B.E.S.T. standards. For teachers, it offers rigorous content with scaffolded support that helps students develop the mathematical reasoning the course requires, not just work through a set of procedures.
Help students think flexibly about shapes and space
Students work with complex two- and three-dimensional figures by mentally cutting, rearranging, and combining familiar shapes in new ways. These decomposition strategies help students solve a wider range of problems than formulas alone.
The course also helps students recognize how often right triangles appear across geometry. They show up when students find the distance between two points, derive the equation of a circle, calculate the area of a hexagon, and use trigonometric ratios to connect side lengths and angle measures.
A question such as “How could you find the height of a building by measuring the angle to its top?” becomes more than a formula exercise. It gives students a chance to see how similarity and trigonometry work together.
Build reasoning from patterns to proof
Throughout the Florida B.E.S.T. Geometry course, students sharpen their ability to think logically. They look for patterns, form conjectures, test ideas with examples and counterexamples, and build formal proofs.
This progression matters because proof should not appear as a completely separate task. Students first explore what may be true, then gather evidence, challenge their thinking, and explain why a conclusion holds.
The revised course supports that full arc of mathematical reasoning, helping students develop habits that can serve them throughout geometry and beyond.
Scaffold geometric constructions
Geometric constructions can become a list of steps if students do not understand the relationships behind them.
The course introduces constructions gradually. Students complete partially finished constructions, then use triangle congruence criteria and line and angle relationships to explain why each step works. This helps students connect the procedure to the underlying geometry rather than simply memorizing directions.
The online course provides scaffolded practice with these ideas. Teachers can then have students apply that reasoning offline as they complete full constructions independently.
Connect new geometry to what students already know
The revised course builds on students’ prior knowledge throughout.
Cavalieri’s principle and other decomposition strategies connect familiar area and volume methods to approaches that apply more broadly. Students extend their surface area reasoning with new trigonometric tools and discover right triangles in places they may not expect, including as a natural path toward the equation of a circle.
These connections can help students see geometry as a connected system of ideas instead of a collection of separate topics.
How can teachers use the Florida B.E.S.T. Geometry course?
The course is designed to work alongside the geometry instruction you already have planned. Open it beside your pacing guide and find the topic you are teaching now.
You might use a resource to introduce a new representation, reinforce a concept after instruction, give students additional practice, or provide another explanation when a challenging idea has not clicked yet.
The scaffolded construction sequence can support students as they move toward independent work. The emphasis on patterns, counterexamples, and proof can also create more opportunities to ask students not only for an answer, but also for the reasoning behind it.
