66 Each of the levels will have about 5-10 exercises.
Level 1
Given: Randomly Generated isometric projection of Cubes in a 3×3×3 space. Each side of each cube
will be color coded. Isometric will be able to be manipulated for a 360˚ view in all directions.
Students: Create all three orthographic views of same object. Squares will be created in corresponding
colors to those of isometric projection.
Level 2
Given: Randomly Generated orthographic projection of squares in a 3×3 space.
Students: Create isometric view of same object using cubes. Isometric will be able to be manipulated
for a 360˚ view in all directions.
Level 3
Given: Randomly Generated isometric projection of Cubes in a 4×4×4 space. Each side of each cube
will be color coded. Isometric will be able to be manipulated for a 360˚ view in all directions.
Students: Create all three orthographic views of same object. Squares will be created in corresponding
colors to those of isometric projection.
Level 4
Given: Randomly Generated orthographic projection of squares in a 4×4 space.
Students: Create isometric view of same object using cubes. Isometric will be able to be manipulated
for a 360˚ view in all directions.
Level 5
Given: Randomly Generated isometric projection of Cubes in a 5×5×5 space. Each side of each cube
will be color coded. Isometric will be able to be manipulated for a 360˚ view in all directions.
Students: Create all three orthographic views of same object. Squares will be created in corresponding
colors to those of isometric projection.
Level 6
Given: Randomly Generated orthographic projection of squares in a 5×5 space.
Students: Create isometric view of same object using cubes. Isometric will be able to be manipulated

In this stage of the CRIOSAT treatment you will be given a three dimensional object. With this object you will have to create the front, top, and side views of the object. You may use the control buttons provided to move the object and see it from different sides. The controls are located to the upper right portion of the three dimensional object, as seen below.
The buttons labeled up, down, left and right will turn the object in the indicated direction. The buttons labeled “rot” will rotate the object. The button labeled “reset” will put the object back into starting position. The button labeled “mouse mouse” will allow you to click on the object and move it however you wish; if the “mouse move button is green then it is turned on, red means off.
The goal is to move the object however you need to in order to make the different views. Below is an example of a correct solution for a top, front, and side view.
You enter your answer by clicking on the empty boxes to the right of the three dimensional figure. One click will place a block in an empty space and a second click will make that block disappear. When you have finished your solution for all three views, click on submit. When you click submit, it will

show you your solution, the correct solution and whether or not you got the item correct. It will also show you what parts are correct and incorrect.
When you see the correct solution, you may move the object still to see how you got the answer correct or incorrect. Then Click the “next question” button to continue. When you have completed enough items you will move to the next level.

In this stage of the treatment you will be asked to do the opposite of the last stage. You are given the front, top, and side views. You will have to create the three dimensional view. In the screen below you can see that the front, top, and side view that are given and the blank space provided for the three dimensional figure that you are to create.
The controls in the upper right work the same as in the last level. There are some new features though. In this level there are two ways to place the cubes where you want them. First look at the buttons along the bottom, which are labeled “reset”, “front”, “side”, “top”, and “place blocks”. These buttons are seen below.
The reset button moves the three dimensional object to a starting position. The front button will show you what your three dimensional object looks like from the front. The side and top buttons shows your object from those angles. The button labeled place blocks, switches between place blocks and remove blocks. This button tells you whether you can place new cubes or remove ones that are already there.
You can place cubes by clicking on the transparent spheres, as seen below. When you click on a sphere a cube will appear in its place.
72
You can also place cubes by clicking on the squares at the bottom of the screen. Each layer of the object is separated and labeled. By clicking on the square once a cube will appear. If you click on the square a second time the cube will be removed. You can tell that a cube has been placed because the square you click on will enlarge. View the image below to see how this works.
When your front, side, and top views look the same as the given views, click on the submit button. This will show you if you are correct and what you got correct or incorrect, as seen below.
73
When you have seen your answer and compare it to the correct answer, click the next question button. This will give you a new item. If you need to read these instructions again, click on the show instructions button.
