isosceles+ : geometry sketchpad
Pros: Tutorials are excellent for reviewing concepts and assessing knowledge either before or after an in-class lesson.
Cons: Manipulating and constructing figures can be tricky, so kids will need plenty of time to practice.
Bottom Line: Versatile high-tech, hands-on tool is useful for teaching, exploring, constructing geometric figures.
Use the tutorials to test kids' knowledge either before or after a unit that applies to the content in the tutorials. For example, after kids learn about the Pythagorean theorem, have them complete the related tutorial individually or with a partner. Then move to the sketchpad and have kids construct a triangle and add measurements for two sides. They can then use the Pythagorean theorem to find or demonstrate the measure of the third side.
Kids can begin using the app either by checking out the tutorials or by going directly to the sketchpad. Tutorials teach kids concepts related to geometry, and each is followed by a series of assessment items. The sketchpad is an exploratory tool with numerous options. Kids can create free-form sketches or use the drawing tool to combine lines, circles, conics, arcs, and circles to create complex figures. Some of the more interesting features include the ability to insert images and graph functions, add text annotations and mathematical expressions, and easily save and share drawings.
As they view the tutorials, kids can learn and test their knowledge of lines, circles, triangles, and more. Assessment questions that follow the tutorials include multiple-choice questions as well as problems that require kids to construct lines and figures with specific features. This is a great way for kids to review and practice important concepts. By using the sketchpad, kids are encouraged to learn through exploration as they construct, manipulate, and edit lines and figures. It's also an excellent way to boost kids' confidence in using technology.

Great Platform for Engaging Geometry Sketches
I love the different tools the app has. You can make tic marks and use arcs to construct shapes. You can also type next to a shape or point to label it or even give instructions or explain what you did. The most challenging aspect of the app is that it does not have clear instructions on how to do all of these things. It takes quite a bit of time messing around in the app to figure out how to create the figure you want to. I think this app could definitely help my students create helpful drawings in Geometry and could provide a digital way to do constructions. However, it would require quite a bit of class time to make sure all the students understood how to use all the tools it provides.
