I am co-presenting at our district technology inservice on ways to integrate technology into both math and literacy. If you're interested in finding out about ways you can integrate Padlet, DoodlecastPro (Explain Everything, Educreations,etc) and PicCollage, feel free to check out our presentation link above. If you have any questions, please don't hesitate to contact me.
My co-presenter is a 5th grade teacher and as such we have many examples from both of our classrooms. YOu'll also find links to Padlet boards with more examples as well as video links with tutorials to get you going.
