### Math:

Dear Parents,

For the next two weeks, your child will be learning about 2-D shapes. The goals will

be for your child to use shapes to make other shapes, to identify shapes that are

congruent (the same size and shape), and to recognize symmetry in shapes. These

skills will help your child to understand that many shapes are related to one another

and that shapes can be sorted and given the same name, such as a set of

parallelograms or a set of triangles. Your child should begin to notice interesting

geometric designs in his or her world. You might talk to your child about how these

designs have been created. At the end of the chapter, your child will be using

knowledge of shapes to create geometric designs. Throughout the two weeks, you

and your child may engage in activities such as:

•  Your child can look for shape puzzles at home. Look in resources such as

newspapers and puzzle books. Your child could bring a puzzle to school to display

on a class bulletin board or puzzle table.

• Your child can find and list things around the house that have more than one line

of symmetry, and sketch at least 4 of these items and show the lines of symmetry.

• Your child could plan a symmetrical design for one wall of a bedroom or some

other room in the house. This might include the placement of pictures or posters

on the wall. Your child can draw a sketch of the symmetrical design, draw the line

of symmetry, and describe how the design was created.

• Your child can find something at home, such as a rug, a vase, or a bedspread, that

has an interesting geometric pattern. Have your child draw the pattern and describe

attributes such as congruent shapes, lines of symmetry, and colour. Your child should

then describe how the pattern was made. This is called the pattern rule. Your child

might take the real object or a drawing of the object to class to share with others.

You may want to visit

www.mathk8.nelson.com for more suggestions to help your child

learn mathematics and for books that relate children’s literature to 2-D geometry. Also

check the Web site for links to other sites that provide online tutorials, math problems,

and brainteasers.

If your child is using a

Mathematics 3 Workbook, pages 57–63 belong to Chapter 7.

There is a page of practice questions for each of the 6 lessons in the chapter and a

Test Yourself page at the end. If your child requires assistance, you can refer to the

At-Home Help box on each Workbook page.
