Quick Draw - Shape Have students draw the following shape. Have them focus on the lengths and proportions. Have them edit their work if it is not correct. Then, have them imagine the shape turned 90 or 180 degrees to the right or to the left and draw that shape. You do not need to use the terms “ 90 degrees” or “ 180 degrees”. Instead, you may choose to guide students to use the sides or the given letters to match the rotation path. For example say, “Turn the shape so that the letter is right here. ” © DMTI (2018) | RESOURCE MATERIALS
