 Box 1-
 *Two yellow equilateral triangles
 *Two yellow, two green right-angled isosceles triangles
 *Two yellow, two green, two gray right-angled scalene triangles
 *One red smaller right-angled scalene triangle
 *On red obtuse-angled scalene triangle<br>(Each triangle has a black line along one side)<br>

 === Presentation  ===
 #Invite the child to remove the triangles from the box, and then sort the triangles according to shape.
 #Having done this, ask the child to separate each pile according to color, resulting in various piles of triangles having both shape and color in common.
 #Isolate the two red ones to be used later.
 #The directress takes the pile of two equilaterals and separates them in such a way that the two black lines are facing each other.
 #Watch, these black lines are like a magnet.
 #Slide the two triangles together so that the black lines meet.
 #Invite the child to do the same, leaving the joined triangles in place.
 #Identify the figures that have been constructed: a yellow rhombus, a green square, and a gray rectangle.
 #The directress identifies the other three figures as common parallelograms (parallelogram: Greek parallelogramium &lt;parallelos, parallel, and grame, figure&gt;).
 #&nbsp;Therefore a parallelogram is a plane figure having parallel sides.
 #By simultaneously running two fingers along two parallel sides, the directress gives a sensorial impression of parallel.
