WELCOME TO GRADE 4!! EXPLORE THE SUBJECT TABS TO DISCOVER WHAT YOU ARE LEARNING THIS YEAR!!
SS4.1: Demonstrate an understanding of time by:
reading and recording time using digital and analog clocks (including 24 hour clocks)
reading and recording calendar dates in a variety of formats
SS4.2: Demonstrate an understanding of regular and irregular 2-D shapes by:
recognizing that area is measured in square units
selecting and justifying referents for the units cm² or m²
estimating area by using referents for cm² or m²
determining and recording area (cm² or m²)
constructing different rectangles for a given area (cm² or m²) in order to demonstrate that many different rectangles may have the same area.
In this unit of measurement we will be learning about how to measure time using a calendar and a clock and how to measure area of regular and irregular shapes.
In our first lesson we are going to be learning about how to write dates using metric notation and in words and numbers. We are also going to write a date when looking at a calendar.
Watch the videos below to learn to write the date in different ways.
Go to Google Classroom and complete the assignment called, Lesson 1: "Calendar Time" in the Classwork section under the Math 5. Measurement Unit.
Turn in the assignment for grading.
For extra practice work on learning about measuring time, go to IXL Math Grade 4 Time Section and work on the following: Q.1 to Q.14.
In the last lesson you learned how to write calendar dates in a variety of ways. In this lesson you will be learning how to read an analog and a digital clock.
You will also be learning how important the hour and the minute hand are when telling time on an analog clock.
Watch the videos below to learn how to read analog and digital clocks.
Go to Google Classroom and complete the assignment called, Lesson 2: "Exploring Time" in the Classwork section under the Math 5. Measurement Unit.

For extra practice work on learning about measuring time, go to IXL Math Grade 4 Time Section and work on the following: Q.1 to Q.14.
You have been learning how to tell time using an analog and a digital clock.
In this lesson you will continue practicing how to tell time in different ways. To help you understand how to tell time you will be making your own analog paper clock to help you.
Watch the videos below to learn how to read analog and digital clocks.
Go to Google Classroom and complete the assignment called, Lesson 3: "Telling Time" in the Classwork section under the Math 5: Measurement Unit.
Turn in the assignment for grading.
For extra practice work on learning about measuring time, go to IXL Math Grade 4 Time Section and work on the following: Q.1 to Q.14
In the last two lesson we have been learning how to tell time to the nearest hour, half hour, and nearest 5 minutes by skip counting. You also have been learning how to write time two ways. Make sure to keep using your practice paper clock to help you tell time.
In this lesson you will be telling time to the nearest minute. Remember, skip counting by 5 will help you when telling time on an analog clock.
Watch the videos below to learn how to read analog clocks to the nearest minute.
Go to Google Classroom and complete the assignment called, Lesson 4: "Telling Time to the Nearest Minute" in the Classwork section under the Math 5: Measurement Unit.

For extra practice work on learning about measuring time, go to IXL Math Grade 4 Time Section and work on the following: Q.1 to Q.14
We have been working on telling time using an analog and a digital clock.
In this lesson we will be learning how to tell time using the 24-Hour Clock. The 24-hour clock is a way of telling the time in which the day runs from midnight to midnight and is divided into 24 hours, numbered from 0 to 24. It does not use a.m. or p.m. This system is also referred to (only in the US and the English speaking parts of Canada) as military time.
24-hour clock time is used in computers, military, public safety, and transport. In many Asian, European and Latin American countries people use it to write the time.
Watch the videos below that help explain how the 24-Hour Clock works.
Go to Google Classroom and complete the assignment called, Lesson 5: "The 24-Hour Clock" in the Classwork section under the Math 5: Measurement Unit.

LESSON 7 - COVERING SHAPES
You just finished learning about perimeter of regular and irregular shapes.
In Lesson 7 we are going to be learning about area. Area is calculated by determining the number of units that cover the total surface of a shape. The units must be the same size and congruent. We will be using pattern blocks to determine how many units a certain shape is.
Remember, Area is the total number of units needed to cover a surface completely.
Watch the videos below to learn to how to calculate area using pattern blocks.
Go to Google Classroom and complete the assignment called, Lesson 7: "Covering Shapes" in the Classwork section under the Math 5. Measurement Unit.
Turn in the assignment for grading.
LESSON 8 - EXPLORING AREA
In the last lesson, you learned that area is calculated by the total number of units used to cover the surface of a shape. We used patterned blocks to determine the area.
In lesson 8 we will be exploring area using square units. Just like perimeter, area can be calculated using different units of measurement including cm and meters represented in "square units" (cm squared, meter squared). You will be able to explain why the square is a most efficient unit of measuring area.
Watch the videos below that help explain how area is calculated using square units

LESSON 9 - Measuring Area in Square Centimetres
In the last lesson we looked at measuring the area of a shape using square units.
In this lesson we are going to measure different shapes using square centimetres. Centimetres squared can be written as cm². We will be using square centimetres to measure area. You will also be finding benchmarks for a square centimetre.
Watch the videos below that help explain how area is calculated using square centimetres.

LESSON 10 - Estimating and Measuring Area
In the last lesson we looked at measuring the area of a shape using centimetre squares
In this lesson we are going to estimate and measure area of different polygons. We will be using square centimetres to measure area.
Watch the video below that help explain how to estimate the area of polygon when it does not follow the boxes on a 1cm grid. Make sure to follow the three step rules to estimate the area.
