This ActivInspire flipchart includes aid for lessons 15.1 through 15.4.
There are problems and teaching aids for each lesson taught in Topic 15.
"I can" statements and differentiated "exit tickets" are also provided for each lesson.
I have included a PDF version of the flipchart, too.
Much of this product could be printed for partners or centers.
More Topic 15 products including practice pages for each lesson and task cards for each lesson are found on my page:
I hope I can help you help your babies navigate through this brave new math world!!! Blessings, Stacey Robinson
