Roll out cookie dough and cut into various shapes using the cookie cutters. Ensure there is a variety including triangles and at least one other shape, such as circle, square or rectangle. Place on a baking sheet and bake according to the package directions.
Prepare a range of sandwiches. Use the cookie cutters to punch out shapes in them and a knife to divide some into triangles, cutting corner to corner, and squares, cutting midline to midline.
Show the demonstration shapes to the students and discuss their properties. Have a quiz and ask the children to call out the names when you show them the shapes.
Place the sandwiches and cookies on plates and show the students. Each student then asks for a specific shape cookie or sandwich. For example: "Can I have a triangle sandwich?" or "May I have a circle cookie?" If the student fails to mention the shape in his request, prompt him by asking which shape he would prefer.
Tell the student to take the cookie or sandwich but do not mention the shape when you speak. For example, simply say "Take it" or "You choose." Say nothing else and watch carefully while the student takes the item. If the item taken matches the spoken request, reinforce by repeating the sentence and giving praise.
Correct the mistake if the child does not take the corresponding item. First tell him the name of the item for which he reached, such as "You wanted the circle cookie." Ask him to select the correct shape. Distract their attention by asking him to look away, covering the cookies or clapping hands. Offer the plate again for the child to make a further request.
Continue using the same procedure in various lessons, such as art, requiring the student to request art equipment in specific shape, and in building tasks, asking for blocks or bricks of specific shapes.
Keep a note of the student's performance to enable you to keep a track of his understanding.
Use a range of worksheets to practice matching and drawing activities. Allow the students to work in pairs so that each can give directions to the other such as "Color the triangle red" or "Color the square blue."
Complete a class scavenger hunt for each student to find as many examples that he can of named shapes.
