First Rectangular Box

• Demonstrate the exercise by first bringing the First Rectangular Box to the working mat or table
• Remove three pairs of identical triangles and place them randomly and show the child how to handle the triangle.
• Isolate any one triangle and pair it by placing it with black lines facing and then slowly bring them together
• Repeat the exercise with the other two pairs of triangle.
• After joining the pairs mix them and invite the child to repeat.
• Gradually introduce more triangles to the child as she works till she has handled each pair

The Second Rectangular Box (Blue Triangles)

• Demonstrate the exercise by first inviting the children to gather around you and by bringing the Second Rectangular Box to the working mat or table
• Remove a pair of identical triangles and place them randomly on the mat
• Show the child how to join them along any side
• Hold one triangle using your left index finger and slide it slowly the other triangle against the triangle on the left hand.
• Allow the child to see the new shape formed and ask the child to identify it.
• Continue moving along all sides until you reach the original position.
• Repeat the exercise with the other pairs one at a time
• In the second part of the exercise, remove a paid of identical triangles and place them randomly on the mat, adjacent to each other.
• Encourage the child to flip one triangle over and join it with it’s identical pair to see a new shape
• Now, slide the triangle to make other figures.

Triangular Box

• Bring the Triangular Box to the working mat or table
• Allow the child to remove all of the triangles and place them randomly on the mat.
• Isolate the grey and green triangle and match them along the black lines.
• Place the green triangle below the grey triangle as the child observes pairing
• Show the child how compare and verification of equivalences of green triangle over grey triangle
• Similarly, follow the procedure for red and yellow triangles
• Gradually mix the triangles and invite the child to repeat the exercise in front of you once so that you can correct an error if a child makes one.
• Encourage the child to do the activity individually.

Large Hexagonal Box

• First, bring the Large Hexagonal Box to the working mat
• Now, ask the child to remove all of the triangles and place them randomly on the mat
• Make a red rhombus, a grey parallelogram and a yellow hexagon by following steps;
• First isolate the two red triangles
• Join them along the black lines to form a rhombus
• Now, isolate the two grey triangles, and join them along the black lines to form a parallelogram.
• And lastly, place the large yellow equilateral triangle in front of the child and encourage the child to look for three yellow obtuse-angled triangles
• Now, isolate them and match to form a hexagon.

Small Hexagonal Box

• Demonstrate by first bringing the Small Hexagonal Box to the working mat and place them according to their color and size
• Join them along their respective black lines to form various shapes of red rhombus, grey hexagon and green trapezium
• Now, demonstrate and show the child how to superimpose the red rhombus and, in turn, green trapezium onto the onto the grey hexagon and remove.
• Encourage the child to do the activity individually and monitor the activity and assist the child when it is necessary.
