Solving shape puzzles requires problem solving, rearranging and spatial memory. Assign each puzzle piece a scent that relates to the image of the completed puzzle. For example, if the puzzle depicts a pine tree, dab each puzzle piece with a cotton swab soaked in essential pine oil. The scent will help students remember the image and guide them in placing the pieces together. Essential oils are potent so only use a single dot for each puzzle piece.
Paste letters cut from textured fabrics on flashcards and allow the children to touch them while they work. Coordinate the type of fabric with the sound of the letter, for example, use silk and satin for soft sounding letters and wool or carpet for sharper sounds. Encourage the children to feel the letters with their fingers helps them memorize the flow and position of each line and curve. As you teach the sounds, instruct each child to feel the particular letter you're referencing with his fingers.
Create an over-sized world map with each region dusted in a particular spice or scent. Choose scents that correlate to a popular export or food in that country to enhance the cultural value for your students. For example, paste a patch of cayenne pepper over Mexico or orange oil over Spain. Even if you can't find an appropriate spice for every region of the world, creating a geographic "scratch and sniff" helps the children differentiate small groups of similarly sounding countries.
Help children learn opposites through touching. Fill four pairs of bins with opposite contents. For example, the first bin would have cold water, while the second bin contained warm water. Another bin holds smooth, silky scarves while the opposite bin holds strips of rough, industrial carpeting. As you teach the opposite concepts, have each child put one hand in either bin. For example, if you were teaching "hot and cold" the children would all place one hand in the hot water and one hand in the cold water.
