Yesterday I ended up having a preschooler in my room while I was doing work after school. I put her on geometry pad and she did very, very, well on it. She had a lovely time making patterns and showing me her creations. This reminded me that if I give students free reign to choose a program, many choose this to play with and create patterns. I think given a chance, students enjoy creating their own original art. My geometry class will soon start learning about congruent triangles after they learn about classifying angles. I've decided they can make a small book using Book Creator on classifying triangles by sides or angles using the geoboard for the illustrations and they can put in the information using text. The next step in the process would be to have students using showme or other such program to make a presentation for the different theorems used in proving congruent triangles.
Each day I find more things I can do with the free apps I have. I will start this in about 2 weeks.
