Language: Content Compatible
Learning Strategies / Social and Skills Development:
Students will demonstrate understanding of a pattern by creating patterns that repeat.
Time Frame:
One class period of 45 minutes
Materials Needed:
- shape blocks
- shape stencils
- long strips of paper
- pencils
- crayons
Description of Assessment (Performance Project):
Pre:
Each student needs one of each of the shape blocks. The teacher gives a clue about the mystery shape. After each clue the students choose which shape might be the mystery shape. Based on the continuing clues, students may change their choice if needed. For instance, if the shape is the rectangle, clues might be: "The mystery shape has four sides.", "My shape has two long sides and two short sides.", and "The long sides of the mystery shape are equal". After three or four clues, the students may call out the name of the mystery shape using the phrase "Es un ______." Continue this activity for several more shapes, and on other days, as a quick review. For these reviews, have students think of, and present clues for the mystery shapes.During:
The students will then use the shapes to create patterns at their seats. Students create three different patterns, each having three different shapes and/or characteristics in the section that repeats. The teacher can move about the room asking students to use the phrases listed above to explain their patterns.Post:
They can then use stencils to draw one of their patterns on a long piece of paper. Upon completion, they should explain to the teacher or teaching assistant their pattern, using the phrases listed above.Extension:
Some students will be able to write the names of the shapes on their pattern. Have them do this if time allows.
