I've used these before, but this year I changed several of my resources and had a much more successful lesson.
BooksI used the books Grandfather Tang's Story and Three Pigs, One Wolf, and Seven Magic Shapes
PicturesI took close-up pictures of the templates used in each book, which I displayed on my SMART board.
Magnetic TangramsI have a set of large foam tangrams that I use to demonstrate with. Before starting my lesson this time around, I hot-glued magnets to the back of each piece. Now I can use them on my whiteboard as I demonstrate, which makes the demonstration visible for all students.
Both of these visuals added success to my lesson. In the past, my students had to refer to tiny 3 cm square pictures, now the large image on the SMART board combined with my step-by-step demonstration on the whiteboard, enabled all of my students to build the shapes successfully!
Do you have other Tangram books or resources that you've found successful?
