The purpose of this activity is for students to connect flat shapes to objects in the environment. Students look at an illustration of objects in the environment and match them to the shapes they look like. Students may match each shape with multiple examples in the image. Students discuss how the objects and the shapes are alike. When students make and describe their own choices for how they represent real-world objects with geometric shapes, they prepare to model real-world problems with mathematics (MP4).

• Invite students to share which objects they matched to each shape.

The purpose of this activity is for students to identify shapes that are the same regardless of their size or orientation. While students may name the shapes in the activity, students do not need to identify the shapes in order to match the shapes that are the same. When students observe that a shape is the same even though the size, color, and orientation may differ, they identify a common mathematical property of the shapes (MP7).

• Display the problem with a square.
• “¿Cuál figura es la misma? ¿Qué observaron que les ayudó a decidir que esa figura es la misma?” // “Which shape is the same? What did you notice that helped you decide they are the same shape?” (The second one because it isn’t stretched out like the first shape. The second shape because they are both squares, one is just smaller.)

The purpose of this activity is for students to choose from activities that offer practice with number and shape concepts.

Students choose any previously introduced stage from these centers:

• Picture Books
• Bingo
• Shake and Spill

• “¿Cuál centro disfrutaron más hoy? ¿Qué disfrutaron de este centro?” // “Which center did you enjoy most today? What did you enjoy about this center?”
