FACTS/TIPS

2 Times Table

Double it! Two times a number simply means add the number twice.

2 x 2 is actually 2 + 2 and 2 x 6 is the same as 6 + 6.

We can also skip count in twos to arrive at our answer, 0, 2, 4, 6, 8...

2x1=2 or 1 group of two

2x2=4 or 2 groups of two




2x6= 12 or 6 groups of two

WEEK 1: NOTATION & NUMERATION

SUB-TOPIC: SKIP COUNTING

Name: __________________________________________ Date: _________________________

FACTS/TIPS: Skip counting has a pattern.

To identify patterns, you can either add or subtract.

PRACTICE EXAMPLES:

Can we identify the patterns below and insert the missing values?

2, 4, 6, 8, ___ = 2, 4, 6, 8, 10

We keep adding 2s, therefore the missing value is 10.

5, 10, 15, 20, 25, ___ = 5, 10, 15, 20, 25, 30

We keep adding 10s, therefore the missing value is 30.

3, 6, 9, ___, ____, 18 = 3, 6, 9, 12, 15

We keep adding 3s, therefore the missing values are 12 and 15.

14, 12, 10, 8, ___ = 14, 12, 10, 8, 6

We keep subtracting 2s, therefore the missing value is 6.

ON YOUR OWN

and the digit in the ones place remains the same.

22, 32, 42, 52 - Here the digit in the tens place is increasing by 1

and the digit in the ones place remains the same.

65, 55, 45, 35 - Here the digit in the tens place is decreasing by

1and the other digit remains the same.

SUB-TOPIC: EXPANDED NOTATION

Name: __________________________________________ Date: _________________________

FACTS/TIPS

Expanded notation is when we write out the number by showing the

value of each digit. Place value or arrow cards are a great way of

showing the value of each digit.

Note: Expanded notation can be written in both number and word

forms.

PRACTICE EXAMPLE

Standard form 1 576

Standard form 7 043

Expanded/number form = 7 000 + 0 + 40 + 3 or 7 000 +40 + 3

Word form = 7 thousands + 4 tens + 3 ones or 7 thousands + 0 hundreds + 4 tens + 3 ones

+

ON YOUR OWN

Write the numbers below in expanded notation using both number

and word forms.

a) 4 289 Number Form ________________________________________

Word Form ________________________________________

b)9 015 Number Form ________________________________________

Word Form ________________________________________

c) 2 536 Number Form ________________________________________

Word Form ________________________________________

TOPIC: EXPANDED NOTATION

Name: ________________________________ Date: _____________________

FACT/TIP

Numeral expander shows how a number can be expressed in

different ways. It is made by folding strips of paper.

PRACTICE EXAMPLES:

John was asked to write the number to represent 52 hundreds, 4 tens

and 3 ones or five thousand two hundred forty-three.

This is what he wrote 5 243.

Is John correct? Yes, he is.

5 243 is actually 5 000 + 200 + 40 + 3 or 5 200 + 40 + 3 or

5 thousands +2 hundreds + 4 tens +3 ones

ON YOUR OWN

Cut 2 sets of four strips of paper. Fold each strip to show the numbers

below in expanded form.

(a) 2 367

(b) 9 876

Use the template below as a guide.

Complete the table below.

HOMEWORK

Answer the following questions.

(a) Tim says 4 329 in expanded notation is written as 4 000 + 3

000 + 29. Is he correct? __________

(b) Now he says that 5 879 is written as 5 000 + 800 + 70 + 9. Is he

correct this time? _____________

(c) Look carefully at the number 9 876. Why do we not expand

it as 9 + 8 + 7 + 6?
