Another great blog demonstrating your great maths. Happy Friday!

1
a] 8 ones
b] 8/100=0.08
c] 8 hundredths

2
a] 8 tens
b] 80/100=0.8
c] 8 tenths

3
a] 2 places to the right.

4
a] 3/100=0.03
b] 90/100=0.9
c] 0.05
d] 0.6
e] 5
f] 2

5
a] Her mistake was stupid. She just didn’t move the tens 2 to the right.
b] 48/100=4.8

6
a] You just move 2 spaces downwards.
b] 92/100=0.92
c] 19/100=0.19

7
a] 31/100=0.31
b] 60/100=0.60
c] 85/100=0.85
d] 1
e] 29/100=0.29
f] 58
g] 50
h] 10

8
a] 36/10=3.6
b] 36/100=0.36
c] 36/10/10=0.36
d] 91/10=9.1
e] 91/100=0.91
f] 91/10/10=0.91

9
a] Yes, because when you divide by ten you move 1 place to the right so if you divide again it’ll move 2 spaces to the right like your dividing by 100. Proof. E.g. 26/10=2.6/10=0.26 and 26/100=0.26.

10
a] 54/100=0.54 and 45/100=0.45
b] 31/100=0.31 and 13/100=0.13

1.
a) 8 ones
b) 8/100=0.08
c) 8 hundredths
If we divide by 100, we move the counters by 2 places to the right

2.
a) 8 tens
b) 80/100=0.8
c) 8 tenths

3.
To divide by 100 you move the counters 2 places to the right.

4.
a) 3/100=0.03
b) 90/100=0.9
c) 0.05=5/100
d) 0.6=60/100
e) 50/100=0.5
f) 0.02=2/100

5.
a) Dora made a mistake and moved only one of the counters by 2 places, leaving 4 tens in the same place, which is incorrect.
b) 48/100=0.48

6.
a) To get the correct answer you can move 2 places down on the Gattegno chart.
b) 92/100=0.92
c) 19/100=0.19

7.
a) 31/100=0.31
b) 60/100=0.6
c) 0.85=85/100
d) 0.01=1/100
e) 0.29=29/100
f) 58/100=0.58
g) 0.5=50/100
h) 0.3=30/100

8.
a) 36/10=3.6
36/100=0.36
36/10/10=0.36

b) 91/10=9.1
91/100=0.91
91/10/10=0.91

9. Yes, I agree with Amir, that’s because if you divide twice by 10 is the same as dividing by 100.

10.
65/100=0.65 and 56/100=0.56
42/100=0.42 and 24/100=0.24
The biggest number I made is 0.65

Some more great Maths work Alex, well done.

1a) 8 ones
b) 8: 100= 0.08
c) 8 hundredths
The counters moved to places to the right.
2a) 8 tens
b) 80:100=0.8
c) 8 tenths
The counters moved two places to the right.
3) To divide by 100 move the counters 2 places to the right.
4a) 0.03 b) 0.9 c) 0.05 d) 0.6 e) 50 f) 2
5) She should move the digit two places to the left when dividing by 100.
6a) I should move two places down.
b) 92:100= 0.92
c) 19: 100= 0.19
7a) 0.31 b) 0.60 c) 0.85 d) 1 e)0.29 f) 58 g)50 h) 100
8a) 3.6 0.36 0.36 b) 9.1 0.91 0.91
Dividing by 100 will have the same result as dividing by 10 twice.
9) Yes, each time when I divide by 10 I need to move the digit one place to the left. By dividing twice by 10 I will have to move the digit twice, the same number of places like in dividing by 100.
10) 12: 100= 0.12 and 21:100= 0.21
The greatest possible answer is 66.
The smallest possible answer is 11.
