- Constructive Triangles Montessori

Box 1: Rectangular Box

This is the first box that is introduced to the child. It contains the following:

2 small equilateral triangles with black lines along one of the edge

2 right-angle isosceles triangles with black lines along the hypotenuse

2 yellow right-angle isosceles triangles with black line along one of the sides

2 green right-angle triangles with black lines along the longer right angle sides

2 yellow right-angle scalene triangles with black line along the shorter of the two right angle sides

2 grey right-angle scalene triangles with black line along the hypotenuse

1 red right-angle scalene triangle and 1 red obtuse angle scalene triangle

The black line is used as guide in forming the shapes.

Box 2: Blue Triangles / Second Rectangular Box

The second box contains blue triangles without black lines. Here the child can freely form his shape without using the black line as a guide.

2 blue right-angle scalene triangles

2 blue right-angle isosceles triangles

2 blue equilateral triangles

a pair of smaller blue triangles identical to the shape and size of the red triangles in Box 1

Box 3: Triangular Box

This box contains the following:

3 yellow isosceles obtuse triangles with black lines along both sides of the obtuse angle

4 red equilateral triangles, one with black lines on all sides, three with black lines one one side

2 green scalene right triangles with black lines along the longer of the two sides of the right angle

1 large grey equilateral triangle without black lines

Box 4: Small Hexagonal Box

The hexagonal boxes are my personal favourites. There’s just so many things you can do with them, especially when making equivalence (more of this in the elementary post). Anyway, here are the contents of the the small hexagonal box:

6 red obtuse-isosceles triangles with black lines on the side opposite the obtuse angle

1 large yellow equilateral triangle with no black lines

2 red equilateral triangles with black lines on one side

3 green equilateral triangles, 2 of which has black lines on one side, and 1 with black lines on two sides

6 grey equilateral triangles with black lines on two sides

Box 5: Large Hexagonal Box

The large hexagonal box contains a different set of triangles compared to the small hexagonal box. Here are the contents:

1 large yellow equilateral triangle with black lines on all three sides

3 yellow isosceles obtuse triangle with 3 black lines on the side opposite the obtuse angle

3 yellow isosceles triangles with 3 black lines on both equal sides

2 red isosceles obtuse triangles with black lines on the side opposite the obtuse angle

2 grey isosceles obtuse triangles with black lines on one of the sides of the obtuse angle
