a. Students’ initial descriptions might be “One side of the line is the same as the other”. b. Or “The points can cross the line of symmetry”. c. Students will gain an awareness of the property of ...
Big Idea – We can describe, measure, and compare spatial relationships. to build on students' knowledge of line symmetry and develop students' reasoning with properties of symmetry to develop an ...
