Making triangle-shaped snacks is a way of illustrating what a triangle is to preschoolers. You can make a child’s favorite snack in the shape of a triangle and give it to her during snack time. Alternatively, you can cut cinnamon toast diagonally so as to make two large triangles or four small ones and serve triangle crackers with cheese slices cut in triangle shapes. You can also have children cut pictures into triangle shapes using a blunt scissors before arranging them together.
Triangle collages are a collection of different materials shaped in the form of a triangle. One way of introducing preschoolers to triangles is by using a mosaic kit. It contains various triangle-shaped tiles, which the children can use for preschool mosaic project. Alternatively, you can cut various sizes of triangles from a bright colored paper and invite the children to glue them on a dull colored surface anywhere they wish. Creating a large pattern for the first letter of each of the preschooler’s name is another alternative. They can then glue the paper triangles to the large letter.
Matching up triangles that have identical colors or sizes can be a fun activity to preschoolers. Obtain three heavy papers of different colors, which you can then cut out into triangles with different sizes, including short and wide, long and skinny, or two equal sides. Mix up these triangles and invite the children to match them up. Trace the triangles on a large poster board square and have your children place the triangles in the matching tracings.
During a drawing class, introduce triangle-opening activities to your preschool children. Give a piece of paper to each and draw a dotted outline of a large triangle. Have the children join the dots together to form a triangle. Showing them how to use crayon to connect the dots and having them do it in groups can serve as an interactive art and craft lesson at the same time.
Making snowflakes takes preschoolers through an arts and craft lesson while at the same time introducing triangles to them. Fold a triangle-shaped piece of white paper into two before having them cut off a corner or two using blunt scissors. Children can then hang the snowflake patterns they have made on a window at home, or display them in the classroom.
