Problem: Article: Use 30-40 small, countable, and fairly homogeneous objects: pebbles, marbles, or erasers.  Scatter the objects on a table in front of your students. Explain that in modern math, we use the number 10 as a base. Arrange the objects into several groups of then, and count them for the class. Show the students that four groups of 10 pebbles equals 40. Sketch out the concept on a whiteboard. First, draw a basic T-chart, Write the number 1 in the top-right corner of the T-chart. Then, write a 10 in the top-left compartment. Write a 0 in the (right-hand) column labeled "1," and write a 4 in the (left-hand) column labeled "10." Now, explain to the class that each number you made with the pebbles has its own "place." Make or print out a "number board" that lays out all of the numbers sequentially from 1-100. Show your students how the numbers from 0 to 9 interact with the numbers from 10 to 100. Explain that every number from 10 to 99 is really made up of two numbers, with one number in the "ones" place and a modifying number in the "tens" place. Show how the number "4" signifies "four" when it is in the "ones" place, but acts as a prefix for the set of "40" when it is located in the "tens" place.  Illustrate the "ones" place. Direct the class mark or cover up every number that has a "3" in the "ones" place: 3, 13, 23, 33, 43, 53, 63, 73, 83, 93. Explain the "tens" place. Have the class point out every number with a "2" in the "tens" place: 20, 21, 22, 23, 24, 25, 26, 27, 28, 29. Explain that the "3" in "23" is stacked on top of the "20" that is signified by the "2." Teach your kids to read the "tens" place as a trigger. You can arrange physical objects or draw on a whiteboard. You can explain place value using increments of money, which students have likely already learned to associate with scaled numerical values. For a fun and interactive exercise, try using the students themselves as the "groups" of values. Memory is predominantly visual, and the concept of place value can be abstract until you put it into visual terms. For that matter, numerical symbols themselves can be abstract for young kids! Look for ways to frame group counting and place value so that they come across as simple, tangible, and intuitive. Try using differently-colored chalks or markers to visually demonstrate place value. For instance, write out various numbers using a black marker for the "ones" place and a blue marker for the "tens." Thus, you would write the number 40 with a blue "4" and a black "0." Repeat this trick with a wide range of numbers to show that place value applies across the board.
Summary: Show the kids that it is easier to count in groups of ten. Translate the pebble example into written numbers. Use a number board to illustrate the basic place values. Experiment with other visual teaching tools. Use colors.

Problem: Article: Your gecko may have stopped eating if it has fallen ill or is suffering from an injury.  If you suspect your gecko to be ill, you should take it to your veterinarian for an examination.  Carefully examine your gecko for any of the following signs:  A skin infection may be identified by any area that is red, swollen, or emitting pus. A respiratory issue can be identified by plugged nostrils, laboured breathing, or any unusual noises during respiration. This is caused by dust or high humidity. Metabolic Bone Disease (from lack of calcium and d3) may cause your gecko to have weakness in its legs and jaw or the inability to stand. It may also cause swelling in the abdomen as it can become impacted from the inability to have a bowl movement. Your gecko's eyes may also become cloudy if it is ill or have an infection. You may be able to feed your gecko by hand, if it is comfortable with you picking it up.  There are a few methods of food preparation that may work better than others.  Some experimentation may be required to find which method your gecko likes the best.  Fruit nectars can be applied to a Q-tip.  The Q-tip is then placed near the gecko's mouth.  If your gecko  finds it appealing, it should begin licking and feeding from the nectar on the Q-tip. You may simply hold your gecko in one hand and a prey item in the other.  Introduce the prey item to the gecko, holding it up to its mouth.  Your gecko may take interest and start eating. If your gecko doesn't take live prey items from your hand, you may need to crush the prey before presenting it.  Once crushed, the prey is gently rubbed on the gecko's lips to encourage it to eat. Do not force feed your gecko. Diagnosing any medical issue on your own can be difficult.  If you notice that your gecko is not eating, you should take it for a visit to your veterinarian for a proper examination.  Your veterinarian will be able to accurately diagnose and will work with you to help restore your geckos appetite and health.  You may need to bring a fresh stool sample. Keep any gecko that you suspect to be ill separate from other geckos you may have.  This will keep any potential diseases from spreading to healthy geckos.
Summary:
Look for signs of illness. Hand feed your gecko. Schedule an appointment with your veterinarian.
