How to make a Modular Origami Frog:
We will need a total of337 modules for this project.
265 Green units and 72 White units will be needed.
Step 1:
We will start making a connector unit in white.
Step 2:
Keep adding white such that Row 1 has 5 units and Row 2 has 4 units.

Keep this aside. We will be using it later.
Step 3:
Then build green rows in the below design:
Rows are built by increasing the number of units byone as you proceed:
Row 1 with 7 green.
Row 2 with 8 green.

Step 4:
Keep adding units till you have a row (7th Row) with 13 green units.
Step 5:
In the next Row (Row 8) as usual increase the number of units by 1 but use 1 white unit at both the ends.
This is how it looks at this stepused 12 green units and 2 white units for this row.

Step 6:
Add the next row (Row 9), add 13 green and 1 white unit at each corner.
Step 7:
Add the next row (Row 10), add 12 green and 2 white units at each corner.
Step 8:
Now slowly bring the corners towards each other. We will join the corners using the white units set we made in Step 3.
Here it is joined together.

Step 9:
Start inserting Row 11 with white units.
We will be adding 9 white units

and 12 green units in this row.

Step 10:
Keep adding green and white units.
Row 12 - 11 Green and 8 White units
Row 13 - 10 Green and 7 White units
Row 14 - 9 Green and 6 White units.
Step 11:
Now add only green units.

Keep reducing the number of units by 1 as you proceed to the next row.
Which means,
Row 15 (but only green units) with 8 units, Row 16 with 7 units and go on till you have 4 green units in a row.
Step 12:
Now similarly add white units. In the next row insert 7 units (increase by 1) and thereafter reduce 1 unit as you go on till youhave 3 units in a Row.
This is the model we get at this point. Since we have inserted the green and white units separately, we get a head like structurewith a mouth.

Step 13:
For the thighs of the frog, make this structure.
Step 14:
Make one more such piece.

Step 15:
For the legs, make the below structure.
Step 16:
We will need 2 hind legs and 2 front legs for the frog.

Step 17:
The legs will be glued on to the body of the frog. For this pull out one unit from the leg as shown here.
Step 18:
Apply glue on this unit pulled out.

Step 19:
Glue on the hind leg.
Step 20:
Now insert and glue the front legs.

Step 21:
The thighs made in Step 13 are then glued on.
The math so far is:
Body + Head = 179 Green units
4 Legs x 12 = 48 Green units
2 Thighs x 19 = 38 Green units
Belly/Body = 72 White units

Two coils out of green paper strip have been made for the eyes of the frog.
Step 23:
White circles cut out of paper are glued on the front and back of the coil.
Step 24:
Eyes are drawn using black marker.

Step 25:
The eyes are glued on to the head of the frog to finish it!
