Math

Whole Numbers Units

We will be beginning a mathematics unit on whole numbers. We will explore very large numbers, and develop and refine strategies for adding, subtracting, multiplying, and dividing multi-digit numbers. We will learn which method of computation (estimation, mental math, paper and pencil, or technology) is appropriate in a given situation. We are going to explore strategies, such as using the inverse operation, to check answers to computational questions.

In this unit, your child will:

·        Read and write whole numbers in standard, expanded, and written forms.

·        Use place value to represent and read whole numbers.

·        Compare and order whole numbers.

·        Estimate sums, differences, products, and quotients.

·        Use mental math to add, subtract, multiply, and divide.

·        Add and subtract multi-digit numbers.

·        Multiply and divide 2-digit number.

·        Pose and solve multistep problems.

Here are some activities you can do to enhance your child’s learning:

·        Together, plan the cost of a family outing or trip.

·        Help your child to find and read large numbers in newspapers and magazines.

·        Encourage your child to estimate the total cost of several items as you shop.


Patterning and Algebra

Your child's class is starting a mathematics unit on number patterns. Understanding and producing patterns are important skills that help develop your child's number sense and algebraic reasoning skills.

Patterns occur in nature, art, and many everyday activities. Patterns can be described using numbers, words, models, and formulas.

In this unit, your child will:

·        Write a pattern rule for a number pattern.

·        Identify, extend, and create patterns.

·        Use patterns to pose and solve problems.

·        Use patterns to explore divisibility rules.

·        Find the value of a missing term or factor.

Patterns occur in many forms. Help your child see the patterns that occur in his or her everyday life — in pictures, numbers, or sequences of performing steps.

Data Management

General Outcome:

Collect, display and analyze data to solve problems.
It is expected that students will:

1. Create, label and interpret line graphs to draw conclusions.

2. Select, justify and use appropriate methods of collecting data, including:

• questionnaires

• databases

• electronic media

3. Graph collected data and analyze the graph to solve problems.

4. Conduct a survey and collect data that will help students make inferences about their data.

Geometry (Transformations)

General Outcome

Describe and analyze position and motion of objects and shapes.

It is expected that students will:

1.  Perform a combination of translations(s), rotation(s) and/or reflection(s) on a single 2-D shape, with and without technology, and draw and describe the image.

2. Perform a combination of successive transformations of 2-D shapes to create a design, and identify and describe the transformations.

3. Identify and plot points in the first quadrant of a Cartesian plane using whole number ordered pairs.

4. Perform and describe single transformations of a 2-D shape in the first quadrant of a Cartesian plane (limited to whole number vertices).

Geometry (3-D Objects and 2-D Shapes)

General Outcome
Describe the characteristics of 3-D objects and 2-D shapes, and analyze the relationships among them.
It is expected that students will:

1. Construct and compare triangles and quadrilaterals, including:

• scalene
• isosceles
• equilateral
• rectangles
• parallelograms
• rhombus
• kites

2. construction of right, obtuse, and acute angles (between 0 and 180 degrees)
in different orientations.

3. Describe and compare the attributes of regular and irregular polygons.

4. Create 3D objects using isometric dot paper and construct structures from a picture.


Decimal, Fractions, Percent - Number Sense
General Outcome
Develop number sense.
It is expected that students will:

1. Demonstrate an understanding of place value for numbers less than one thousandths.

2. Relate improper fractions to mixed numbers.

3. Demonstrate an understanding of ratio concretely, pictorially and symbolically.

4. Demonstrate an understanding of percent (limited to whole numbers) concretely, pictorially and symbolically.

5. Demonstrate an understanding of multiplication and division of decimals (1-digit whole number multipliers and 1-digit natural number divisors).
