Classroom Management / Communication:
Seesaw Learning Journal (free)
Seesaw is a student driven digital portfolio. This tool allows students to document their work for the entire year. It is a great way to show progress throughout the year. I highly recommend this tool for RTI documentation as well. Students take a picture of their work and it saves it into a cloud for parents to see. (Great for parent conferences)
Edmodo takes the ideas of a social network like facebook and turns it into a classroom management system. Edmodo allows students to collaborate, take quizes, interactive games, and more. A tool such as this is a must have for any 1:1 initiative. It can truly get your classroom a step closer to paperless.
TooNoisy (free version or $3.99)
Uses the microphone from the iPad to measure the noise level of the classroom. If the students are too loud, the alarm will sound. You can adjust the sensitivity and monitors how long it is on without being set off. It is a great way for kids to be aware of their volume.
Assessments / Instruction
A free game-based learning platform that makes it fun to learn. I highly recommend adding fun questions within the normal curriculum questions. For example, I put a picture of a cartoon character and ask "Who is this character?" The kids really enjoy this program, but it has to be used correctly.
