As you may know from years past, I love both. Actually, I have to keep track of when we do birch landscapes so as not to repeat the theme. Traditionally we do cardinals in grade 2 and I've done birch landscapes in 1st and 4th grades.
This lesson was relatively simple and I owe thanks to Pinterest for the idea of these simple shape cardinals.
After creating the backgrounds, we identified circles, semi-circles and triangles. My little artists cut and combined shapes to create their birds and then glued them down.
