GRADE THREE CONSOLIDATED WORKSHEET

SUBJECT: TABLES

WEEK 11: ORDERING REVIEW

Name: __________________________________________ Date: _________________________



SUBJECT: NOTATION

WEEK 11: Roman Numbers

FACTS/TIPS:

The present number system that we use is called the Hindu Arabic

Numeral. Roman Numerals is another number system that we use

where letters represent numerals.

PRACTICE EXAMPLE:

The Romans used their fingers to form their number system. This is

what it looks like.

As time went by the iiii was changed.

Whenever a smaller Roman numeral comes before a larger Roman

Numeral the values are subtracted.

So iiii is now iv

iv = one less than five

OR

5 – 1 = 4

No Roman numeral can be used more than three times.

V is never repeated.

ON YOUR OWN:

Write the Roman Numeral for the Hindu Arabic Numerals below.

Numeral the values are added.

PRACTICE EXAMPLES:

Let’s look at this Roman Numeral.

WEEK 11: LENGTHS OF NON-STANDARD UNIT

Name: __________________________________________ Date: _________________________

FACT/TIP:

Length is described as the distance from one point to another. Non-

standard units are units that are not normally used for measurement.

Each would have its measurement.

PRACTICE EXAMPLE:

Some non-standard units that we can use to measure length are a

book, pencil, hand span, foot, and paper – clip.

Look at the length of this object.

Length length

Walk along the edge of a room in your home. How many feet length

is the edge of the room?

Your foot should be placed like this.

ON YOUR OWN:

Draw arrows to show where on the shape we can measure the

length.

Use your handspan to measure the end of a table in your home.

HOMEWORK:

1. Which of these is not a non-standard unit of measurement?

(a) handspan

(b) foot

(c) ruler

(d) tape measure

(e) stride

(f) crayon

2. Measure the long side of a textbook using a clothes peg.

---------------- clothes pegs long

3. Write five examples of things or places that you can measure

the length of e.g. The edge of your yard

(i) ______________________

(ii) ______________________

(iii) _______________________________

(iv) _______________________________

(v) _______________________________






LESSON 2

Name: __________________________________________ Date: _________________________

FACT/TIP:

The standard units of length are the common units used to measure

length.

Some standard units of length are millimeter (mm), centimeter (cm),

meter (m), and kilometer (km).

PRACTICE EXAMPLE:

The units in order of size are:

Smallest to largest

mm cm m km

We use the smaller units to measure the shorter lengths and the

larger units to measure the longer lengths.

So, we could use mm to measure or finger.

ON YOUR OWN:

What units would you use to measure the following items?

(a) Road -

(b) Pencil –

(c) Table –

(d) Book -

Answer: road (km), pencil (mm/cm), table (cm/m), book

(cm)

HOMEWORK:

1. Arrange these units from largest to smallest.

cm mm km m

________________________________________________

2. Write two items each that you can measure with the

measurements below.

(a) mm

(i) ______________________

(ii) ______________________

(b) cm

(i) _______________________

(ii) _______________________

(c) m _______________________

(i) _______________________

(ii) _______________________

(d) Km _______________________

(i) _______________________

(ii) _______________________

3. Why would you use a kilometer to measure the distance from

your home to your school?

WEEK 11: ESTIMATING THE LENGTH

Name: __________________________________________ Date: _________________________

FACTS/TIPS:

To estimate means to make a guess.

To get the exact length we have to measure.

To measure we use a ruler (for shorter lengths) or a meter stick (for

longer length).

The ruler, measuring tape, and meter stick are all called measuring

tools or instruments.

PRACTICE EXAMPLE:

Look at this ruler.

The unit on the ruler is cm.

If we measure 2 cm, we start from zero.

Zero to one = 1 cm

One to two = 1 cm

If we start at 1 then our 2 cm would stop at 3 because there are two

spaces between 1 and 3.

Look at the long edge of your exercise book.

Find the cm measurement on your ruler.

Guess or estimate the length of the long side of your exercise book in

cm.

Now measure the long side of the book with your ruler.

Put the answers in the table below.

Object Estimate Actual Measurement

The long side of the

exercise book

ON YOUR OWN:

Estimate the length of the objects below, in cm, then measure them with your

ruler.

Object Estimate Actual

Measurement

HOMEWORK:

1. Use the mm side of your ruler.

Draw lines with the measurements below.

(a) 5 mm

(b) 10 mm

(c) 8 mm

2. Use the ruler to write the measurement of each strip.

(a)

______ cm

(b)

_______ cm

(c)

________ c





WEEK 11:

Name: __________________________________________ Date: _________________________

FACTS/TIPS:

When solving written statements or problems in Mathematics, we

should read the statements carefully and look for keywords or terms

before solving them.

PRACTICE EXAMPLE:

Read this statement carefully.

Jane has two pieces of string. One piece is 12 cm long and the other

is 12 m long. Which piece of string is longer?

Step 1 – Read the statement.

Step 2 – Look for keywords.

Step 3 – Write short statements.

Step 4 – Solve.

Solution

One piece is 12 cm. The other piece is 12 m.

They have the same number but the units are different.

Since the larger unit is m, the longer piece is 12 m.

Answer: 12 m

ON YOUR OWN:

Read the statement carefully, then solve it.

Mrs. Singh wants to purchase some cloth to make curtains. What unit

of length would she most likely purchase at the store?

Keywords: cloth for curtain, unit of length

Statement:

Answer: meters

HOMEWORK

Read these statements carefully before solving them.

(1) A Grade 3 teacher was taking her class on a walk around

the community. What measuring tool could she use to

measure the length of the journey?

(2) John has an assignment to measure from one end of his

street to another.

(a) What is he measuring?

(b) What unit of measurement would he use?

(c) What instrument would he use?

(3) Sarah was measuring the length of some items in her home

using millimeters. List 5 items she may have measured?
