Teaching analogies is important and fun, but unless students have been exposed to analogies in the past, getting a solid grasp during test preparation can also translate to stress. The most common categories of analogies are:
1. Contrast 2. Part to Whole 3. Part to Part 4. Activity to Result 5. Use
6. Individual to object 7. Measurement 8. Degree of difference to similarity
In the past, I have reviewed a couple of really good apps that teach analogies. For a grade and level break down practice sheets, visit englishforeveryone.org. They have a wealth of great materials.
