Sides and corners asks three things: name the drawing, count the sides or corners, and say whether color or turning changes the name. 4 of the drawings are turned on purpose. Halves and fourths stays with halves and fourths of a circle or a rectangle. A turned trapezoid is still a trapezoid. Color does not change it either. One item asks, "A circle is colored green. Is it a triangle?" The answer is no. If a child says a turned shape is "upside down, so it is different," turn it back and ask again. On the answer line, a square has equal sides and a rectangle is drawn longer than it is tall. On the shares sheet, a fourth is the smaller piece, and two halves make one whole.
