Promote thinking! The 23 lessons in this unit take a variety of approaches to identifying similarities and differences. Picture puzzles reinforce visual discrimination. Word search activities promote single-word and short-phrase analysis. Examples: Find at least 10 ways in which these pictures are different. What makes these words similar: duck, chicken, turkey? Difficulty peaks with finding the similarities and differences in sentences. These step-by-step activities are sure to improve thinking and logic skills. And, because they seem more like games than work, students will have loads of fun while they learn.
