### PRODUCT DESCRIPTION

Explore 2D shapes and 3D figures in a fun way while developing problem-solving and oral communication skills!
Most of the activities suggested in this document have been conceived to allow students to work in pairs, however, they can also be successfully completed individually .
It is important to familiarize students with the Problem-Solving Model (that can be downloaded at no cost in our store) in order to guide them through the problem-solving process.
Students should have opportunities to share their work with their peers. In this regard, it is recommended to reserve 10-15 min at the end of the lesson or unit to allow students to share their work, as well as answer or ask questions.
The tasks can be printed and laminated for longer usage and placed in your Problem-Solving workstation or just printed and used by your students as a one-time activity.
Specific expectations covered in the activities :
 identify and describe common 2-D shapes (e.g., circles, triangles, rectangles, squares) and sort and classify them by their attributes (e.g., color; size; texture; number of sides), using concrete materials and pictorial representations;
 trace and identify the 2-D faces of 3-D figures, using concrete models;
 use and identify 2-D shapes in drawings;
 identify and describe common 3-D figures (e.g., cubes, cones, cylinders, spheres, rectangular prisms) and sort and classify them by their attributes (e.g., color; size; texture; number and shape of faces), using concrete materials and pictorial representations;
 describe similarities and differences between an everyday object and a 3-D figure;
 use 3-D figures to build structures and compose new 3-D figures,
 make 3-D figures using different materials.
