I used Wallwisher to create an online word wall where students can write high frequency words and post on our literacy word wall. I also created a science and social studies word wall where students can add new vocabulary to the board during workstations. We even could create a board for different units of study and students can add vocabulary and find images to describe each particular term.
I could use Skype into my classroom to help students communicate with other students from around the world and learned about different cultures. As many of my students have family in other countries it will be relevant to them learn how they can communicate with their family using this tool.
