Today's lesson introduced the concept of angles in 2-dimensional shapes. Danny counted and circled the number of angles of shown shapes along with writing the shape's names. Then, he drew lines to complete shapes so that it matched the number of given angles. Next, Danny used the number of sides and angles to sort 2-D shapes. He circled shapes from groups that followed the shown attribute rules. Danny finished with a 2-step daily word problem, circling the given numbers and looking for clue words to find the 2 different operations needed to complete the problem.
