Do you use QR codes in your classroom? Can you share how you are using them in the comment?
Every year my students bring a collection of 100 to school. We weigh the collections to compare the weight and practice grouping 100 items. This year my students recorded their grouping activity using Educreations. They took pictures and recorded how they counted.
They embedded the Educreations lesson on their blog to share it with their family and well, with the world! My twitter friends Mrs. Lirenman from Canada and Mrs. Hino from Japan left a comment on our blog. My students were soooo excited and couldn't believe people from other countries could view their blog;)
