5 wooden boxes with lids contain triangles in different sizes, shapes and colors.

**Triangle Box**

**Presentation **

1 The Directress shows the child how to take any one of the box individually to the floor mat.

2 She sits beside the child and places the box of shapes in front of the child.

3 Directress shows how to lay out all the contents on the mat.

4 Box 1 -Trace the lines on the shapes with fingers.

5 Join up the triangles along the line.

6 Then, use the gray triangle as control of error by holding it just above all the shapes made earlier, (not touching) in turn.

7 The Directress then invites the child to put the shapes together, matching the black lines. the resulting shapes are discussed and named.

8 Directress may use the Three Period lesson to teach the child the name of the shapes that could be formed with the various shapes, for e.g. hexagon, triangle, rhombus,...etc.

**Rectangular Box 1**

**Presentation **

1 Invite the child to work with the 'rectangular box'.

2 Show the child where the rectangular box is located on the shelf.

3 When the child has made the selection of the material, begin with the third step after naming the material for the child.

4 Indicate the procedure for carrying the material: one hand on each side of the rectangular box with thumbs on top and fingers on the bottom.

5 Place the box in the upper left side of the rug.

6 Remove the lid and place to the right of the box.

7 Say, "I will make shapes from the triangles."

8 Remove from the box the two green and two yellow isosceles triangles one at a time and place them in a straight line at the bottom of the rug.

9 With the index and middle fingers, trace the black lines on the green triangles.

10 Slide them together, forming a square.

11 Move the square below the rectangle box.

12 With the index and middle fingers, trace the black lines on the yellow triangles.

13 Slide them together, forming a rhomboid.

14 Move the rhomboid to the right of the square.

15 Select from the box ,the two grey, two green, and two yellow scalene right triangles one at a time and place them in a straight line at the bottom of the rug.

16 Trace the black line on the grey triangles.

17 Slide them together, forming a rhomboid.

18 Trace the black line on the yellow triangles.

19 Slide them together, forming a rhomboid.

20 Select from the box the two yellow equilateral triangles and the red scalene triangles one at a time and place them in a straight line at the bottom of the rug.

21 Trace the black line on the two yellow triangles.

22 Slide them together, forming a rhombus.

23 Trace the black line on the red triangles.

24 Slide them together, forming a trapezoid.

25 Replace the material into the box beginning with the trapezoid to the lower left, rhombus in upper left, right angle triangles in right as rectangles, and isosceles triangles as a square.

26 Return the material to the shelf in the manner as indicated in #3.

**Rectangular Box 2**

**Presentation **

1 Invite the child to work with the 'rectangular box'.

2 Show the child where the rectangular box is located on the shelf.

3 When the child has made the selection of the material, begin with the third step after naming the material for the child.

4 Indicate the procedure for carrying the material: one hand on each side of the rectangular box with the thumbs on the top and fingers on the bottom.

5 Place the box in the upper left side of the rug.

6 Remove the lid and place it to the right of the box.

7 Say, "I will make shapes from the triangles."

8 Remove the two isosceles right triangles one at a time, and place them in a straight line below the lid.

9 Slide them against each other, forming a square.

10 Again, slide them together to form a rhomboid.

11 Slide them together, to form a different rhomboid.

12 Select the two scalene right triangles one at a time.

13 Slide them against eachother, forming a rectangle.

14 Again, slide them together to form a rhomboid.

15 Slide them together to form a different rhomboid.

16 Select the two equilateral triangles one at a time.

17 Slide them against eachother, to form a rhombus.

18 Select the one scalene right triangle and the one scalene obtuse triangle one at a time.

19 Slide them together, to form a trapezoid.

20 Replace the material into the box beginning with the trapezoid on thr right.

21 Return the material to the shelf in the manner described in #3.

**Small Hexagonal Box**

**Presentation **

1 Invite the child to work with the 'Small hexagonal box'.

2 Show the child where the small hexagonal box is located on the shelf.

3 When the child has made the selection of the material, begin with the third step after naming the material for the child.

4 Indicate the procedure for carrying the material: one hand on each side of box with thumbs on the top and the fingers on the bottom.

5 Place the box on a rug.

6 Place the box in the upper left side of the rug.

7 Say, "I will make shapes with the triangles."

8 Remove the lid. Select the yellow equilateral triangle and place it to the right of the lid.

9 Select six Isosceles obtuse triangles, one at a time placing them in a straight line below the box.

10 Trace the black line with the index and middle fingers.

11 Slide the triangles together to foram a rhombus and continue until you have made three rhombi.

12 With two hands, make the first two rhombi point to the top of the rug.

13 Slide the third rhombi below forming the hexagon.

14 Slide Hexagon to the left.

15 Select the six grey equilateral triangles, one at a time placing them in a straight line at the bottom of the rug.

16 Trace the black lines with the index and middle fingers.

17 Slide the triangles to form a hexagon.

18 Select the three green triangles, one at a time placing them in a straight line to the right of the grey hexagon.

19 Trace the black lines with the indeax and middle fingers.

20 Slide the triangles together to form a trapezoid.

21 Select two red quilateral triangles one at a time placing them in a straight line to the right of the red hexagon.

22 Trace the black lines with the index and middle fingers.

23 Slide the triangles together to form a rhombus.

24 Replace the material into the box beginning with the red rhombus.

25 Return the material to the shelf in the manner indicated in #3.

**Large Hexagonal Box**

**Presentation **

1 Invite the child to work with the 'large hexagonal box'.

2 Show the child where the large hexagonal box is located on the shelf. When the child has made the selection of the material, begin with the third step after naming the material for the child.

3 Indicate the procedure for carrying the material: one hand on each side of the hexagonal box, with the thumbs on top and fingers on the bottom.

4 Place the box on a rug.

5 Place the box in the upper left side of the rug.

6 Remove the lid and place it to the right of the box.

7 Say, "I will make shapes with triangles."

8 Remove the yellow equilateral triangle and place it at the bottom of the rug.

9 Remove the three isosceles obtuse triangles with the black line on the side opposite to the obtuse angle and place them in a straight line to the right of the equilateral triangle.

10 With the index and middle fingers trace the black line of the equilateral triangle and the black line of one of the isosceles obtuse triangles.

11 Slide the black line of the second triangle against the black line of the equilateral triangle.

12 Continue with the remaining triangles in the same manner, thus forming a hexagon.

13 Indicate the equilateral triangle inscribed in the hexagon by tracing the black line with the index and forefinger.

14 Select from the box the yellow isosceles obtuse triangles with the black line on the two sides adjacent to the obtuse angle and place them in a straight line to the right of the yellow hexagon just formed.

15 With the index and middle fingers, trace the black line of the first isosceles triangle and the black line of the second isosceles triangle.

16 Continue in the same manner with the third triangle.

17 Superimpose the large yellow equilateral triangle over the equilateral triangle formed by the three isosceles triangles.

18 Return the equilateral triangle.

19 Select the two red triangles one at a time and place them in a straight line to the right of the equilateral triangle.

20 With the index and middle fingers, trace the black line on each triangle.

21 Then slide the triangles together at the black lines forming a rhombus.

22 Select from the box two grey triangles one at a time and place them in a straight line to the right of the red rhombus.

23 With the index and middles fingers, trace the black line on each triangle.

24 Then slide the triangles together at the black lines forming a rhomboid.

25 Replace the material into the box, beginning with the grey rhombus.

26 Return the material to the shelf in the manner indicated in step #3.
