Title: Shapes!!

Objective: By the end of the lesson, students will be able to: Recognize each shape when shown to them in class with a 100% accuracy level. Compare different shapes in a worksheet with a 100% accuracy level. Sort shapes into categories based on their attributes, in their home teams, with a 100% accuracy level.

Primary Standards Addressed:

Standards/Benchmarks Addressed:

MAK.1.1 Students read and represent numbers up to 9.

MAK.1.4 Students count with understanding up to 20 objects to solve problems.

MAK.2.1 Students recognize, name, compare, and sort geometric shapes (circle, square, triangle, and rectangle.)

Materials:

Materials and Equipment Needed:

A circle. What is an object that is in the shape of a circle? Answer: A clock. Where else in everyday life do we find shapes? Answer: Shapes are in my home, in school, on the playground, in the store, etc.

Opening: The teacher will take 2 minutes to read the book The Greedy Triangle by Marilyn Burns to the students. This attention grabber will not only focus the children’s attention, but it will also activate students’ prior knowledge about geometric shapes. The teacher will pass out the pattern blocks to each student at the conclusion of the book.

Guided Practice: • Prior to the lesson, shapes cut out of construction paper, glue, scissors, string, hangers, and miscellaneous items have been placed at each table of students.

• “We have just learned four of the major shapes. I want all of you to say out loud these shapes with me.” CIRCLE, SQUARE, RECTANGLE, AND TRIANGLE. Now that we know the names of these shapes, we are now going to make a shape mobile. You have been provided with circles, squares, rectangles, and triangles that have been cut out of construction paper. There are also cups of different items in the shape of the four shapes we have talked about. You need to glue at least four circle objects on your paper circle, four rectangle objects on your paper rectangle, four triangle objects on your paper triangle, and four square objects on your paper square. From there, we

Circles aren’t typically part of the pattern blocks but it has been added for this assessment and lesson. Their shape mobiles will also be formally assessed as this displays their ability to sort and compare the four different shapes discussed in the lesson. A rubric is provided at the end of the lesson detailing how to assess the students using both the pattern blocks and the shape mobile.

Rubric
