Save this template into the student shared.
Have students choose 5 slides they want to keep in
their book and delete the extras.
Have students identify angles, lines and geometric
figures in each picture. Students titled each slide
based on the geometric figures they find in the
pictures.
Students will write sentences explaining what they
saw in the pictures.
Students will use the drawing toolbar at the
bottom of the screen to trace over the lines, angles
and figures.
1. If they do not see the drawing toolbar, go to
view/toolbars/drawing
As an extension, have students use the
digital camera to take pictures of geometric
figures around the school. Students can
then use the digital images for this activity.
See slide 3 and 4 for a student example. Delete this slide
and slide 3 & 4 before using with students.
