Sorting Quadrilaterals

Note to Families
This Home Connection Activity involves sorting quadrilaterals. Although some of these shapes are pretty strange- looking, they’re all related in that they each have 4 sides and 4 corners. Your child may have many different ideas about how to sort the quadrilaterals on the next page, but if he or she runs out of steam, it’s okay for you to mention things like right angles, parallel lines, and symmetry. Have fun!

Cut out the shape cards on the next page. Some of the shapes may look a little strange to you, but they are all quadrilaterals. That is, they all have 4 sides. Look carefully and you’ll find that it’s true! Work with someone in your family to find as many ways to sort these shapes as possible, and list your ideas below.

Three-Dimensional Shape Hunt

Note to Families
We recently started a new unit on geometry. We are using pattern blocks, geoboards, and paper shapes to investigate many different two- and three-dimensional shapes. Besides learning to recognize and name these shapes, we’ll explore how they’re alike and different and what happens when we cut them up, put them together, and move them around by sliding, turning, and flipping them. We’ll learn how to measure the area of some of them, and how to use others to create symmetrical designs. We’ll also consider the shapes that are all around us, both human-made and those occuring in nature. This assignment reinforces what we are learning about geometry.

Have you ever thought about why things are the shape they are? Ever wondered why a cup is round and the rooms in most houses are square or rectangular instead of round? Why dice and ice are cube-shaped and why we eat ice cream out of cones instead of pyramids? Shapes are fun to find and fun to think about! This week, you’re going to go on a three-dimensional shape hunt. All you have to do is search around your house for things that are shaped like cubes, spheres, cylinders, and rectangular prisms (boxes), and list them below. Happy hunting!

Here are some of things we found that are cylindrical:

Bridges in Mathematics Grade 2 Home Connections Unit 6 Module 2 Answer Key 7
This exercise asks your child to count and sketch the faces of two different three-dimensional shapes. “Face” is the term mathematicians use for a flat surface on a three-dimensional shape. The triangular prism pictured to the left has 5 faces: 2 triangles and 3 rectangles. Your child will need a cube and a rectangular prism to do this exercise. One of a pair of dice and a cereal box would be great.

Materials

  • Three-Dimensional Shape Hunt, page 2
  • a cube, such as one of a pair of dice
  • a rectangular prism, such as a cereal box

Instructions
Take a good look at some of the shapes you found to answer the following questions.

How many faces does your cube have? ____________
Are they all the same shape? ____________
Make a sketch of each of the cube’s faces right here:
Answer:
A cube is a three-dimensional solid object bounded by six square faces, and sides, with three meeting at each vertex.
A cube has 6 faces.
They all have the same shape.
