+Introduction to Problem Types
+===============================
+
+Please read the following, watch the videos, and try to solve the problems.
+
+
+Solving Mixed-up Code Problems
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you see a problem like the one below you will need to put the mixed-up
+code in the correct order on the right side. You may need to indent the blocks as well.  There may also be extra blocks that are not
+needed in a correct solution that you can leave on the left side. Click the "Check" button
+to check your solution.
+
+See the video below for an example.
+
+.. youtube:: 0x4yWQ9ZJAg
+    :divid: iwgex1-parsons1-mooc_nested
+    :optional:
+    :width: 650
+    :height: 415
+    :align: center
+
+Try to solve the following mixed-up code problem.  This problem doesn't require any indentation.
+
+.. parsonsprob:: intro-simple-parsons-no-indent-mooc_nested
+   :numbered: left
+   :adaptive:
+   :practice: T
+   :order: 3, 1, 2, 0
+
+   Drag the blocks from the left and put them in the correct order on the right. The text in each block
+   defines the order.
+   -----
+   First block
+   =====
+   Second block
+   =====
+   Third block
+
+Try to solve the following mixed-up code problem. This problem requires indentation.
+
+.. parsonsprob:: intro-simple-parsons-indent-mooc_nested
+   :numbered: left
+   :adaptive:
+   :practice: T
+   :order: 3, 1, 2, 0
+
+   Drag the blocks from the left and put them in the correct order on the right with the correct indentation.
+   The text in each block defines the order and indentation.
+   -----
+   First block
+   =====
+   Second block
+   =====
+       Third block that needs to be indented
+
+Try to solve the following mixed-up code problem. This problem requires indentation and has extra blocks that are not needed in a correct solution.
+
+.. parsonsprob:: intro-simple-parsons-indent-with-dist-mooc_nested
+   :numbered: left
+   :adaptive:
+   :practice: T
+   :order: 3, 1, 2, 0
+
+   Drag the blocks from the left and put them in the correct order on the right with the correct indentation.
+   There is an extra block that is not needed in the correct solution.
+   -----
+   First block
+   =====
+   Second block
+   =====
+   Extra block that is not needed #paired: This block is not needed
+   =====
+       Third block that needs to be indented
+
+The mixed-up code problems have a "Help me" button at the bottom of the
+problem. Once you have checked at least three incorrect solutions you can
+click the button for help.  It will remove an incorrect code block, if you used
+one in your solution, or combine two blocks into one if there are more
+than three blocks left.
+
+See the video below for an example.
+
+.. youtube:: jkKp9V_Z22E
+    :divid: iwgex1-parsons2-mooc_nested
+    :optional:
+    :width: 650
+    :height: 415
+    :align: center
+
+Solving Write Code Problems
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+If you see a problem like the one below, you will need to write code.  The problem
+will have unit tests that you can run to check that your code is working
+correctly.  Click on the "Run" button to compile and run your code.  Look after
+the code area for compiler errors and/or unit test results.
+
+See the video below for an example.
+
+.. youtube:: tQZrw8yUiSs
+    :divid: mooc_nested-write-code-video-ex
+    :optional:
+    :width: 650
+    :height: 415
+    :align: center
+
+Finish writing the code for the following problem.
+
+.. activecode:: intro-sample-write-code-double-mooc_nested
+    :autograde: unittest
+    :nocodelens:
+
+    Write a function called ``double(num)`` that takes a number ``num`` and
+    returns the number times 2. For example, ``double(3)`` should return 6 and ``double(-4)`` should return -8.
+    ~~~~
+    def double(num):
+        # Your code here
+        pass
+
+    print(double(2))
+    print(double(-1))
+
+    ====
+    from unittest.gui import TestCaseGui
+    class myTests(TestCaseGui):
+
+        def testOne(self):
+            self.assertEqual(double(2),4,"double(2)")
+            self.assertEqual(double(3),6,"double(3)")
+            self.assertEqual(double(-1),-2,"double(-1)")
+            self.assertEqual(double(0),0,"double(0)")
+            self.assertEqual(double(11),22,"double(11)")
+
+    myTests().main()
+
+
+
+Solving Write Code Problems with Pop-Up Mixed-up Code Puzzles to Help
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+If you see a problem like the one below, you will need to write code. You can go to the **toggle bar** above the problem description to open a mixed-up puzzle that will help you write the code. 
+The mixed-up puzzle will have blocks of code that you can drag and drop to create a solution. You can also use the "Help me" button to get additional assistance within the puzzle if needed.
