Task 1

12 x 3 = 36

16 – 5 = 11

11 – 5 = 6

6 – 5 = 1

Task 2

64395÷5=12879

7524÷9=836

61395 / 5

9594 / 9

33 / 3

384 / 6

Activity 1:

12 x 3 = 36

36 ÷ 3 = 12

12 ÷ 3 = 4

4 – 3 = 1

Activity 1:

17 × 5 = 85.

21 × 4 = 84.

48 ÷ by 4 = 12.

20 – 4 – 80.

Activity 1:

21 x 4 = 84

84 – 4 = 80

80 / 4 = 20

20 – 4 = 16

16 / 4 = 4

4 / 4 = 1

Activity 1:

17×5=85

21×4=84

48 divided by 4 =12

20 – 4 – 80

well done, can you complete Task 2.

Looks about right!

Activity one.

~

17 x 5 = 85

85 – 5 = 80

80/5 = 16

~

21 x 4 = 84

84 – 4 = 80

80 / 4 = 20

~

16 – 5 = 11

11 – 5 = 6

6 – 5 = 1

~

20 – 4 = 16

16 / 4 = 4

4 / 4 = 1

Welldone Amelia. Was there anything you noticed? a pattern…..

Have you found these ‘calculator’ tasks useful for secondary schools?

Task2:

21×4=84.

84–4=80.

80 / 4 = 20.

20–4=16.

16 / 4 = 4.

4 / 4 = 1.

20 x 5 = 100.

100 / 5 = 20.

20 + 5 = 25.

25 / 5 = 5.

5 / 5 = 1.

Well done Azan. Did you find anything challenging?

Activity 1

1)13×4=52

52-4=48

48÷4=12

12-4=8

8-4=4

4÷4=1

2)9×4=36

36÷4=9

9-4=5

5-4=1

The smallest number of keys I used was 4.

Yes, you can 5 to change 17 to 1. The answer is below.

17-5=12

12×5=60

60÷5=55

55-5=50

50-5=10

10÷2=5

5÷5=1

Activity 2

1)1582÷7=226

2)64395÷5=12879

3)7524÷9=836

4)33÷3=11

5)384÷6=64

6)608÷4=152

The strategy I used was trial and error.

I do not think there are any other ways to solving the problem.

Wow great work and clear working out!

Good work, Hadisa.

I done my maths work and I have sent the email.

Thank you, we have received this- well done :)

Activity 1:

21 x 4 = 84

84 – 4 = 80

80 / 4 = 20

20 – 4 = 16

16 / 4 = 4

4 / 4 = 1

————-

20 x 5 = 100

100 / 5 = 20

20 + 5 = 25

25 / 5 = 5

5 / 5 = 1

Well done Amaan :)

Task 1

17 x 5 = 85

85 – 5 = 80

80/5 = 16

16 – 5 = 11

11 – 5 = 6

6 – 5 = 1

Task 2

1582 / 7

61395 / 5

9594 / 9

33 / 3

384 / 6

108 / 4

There are different solutions that could also work like 63 divided by 3 but I chose the above.

Well done :)

Activity 1:

21 x 4 = 84

84 – 4 = 80

80 / 4 = 20

20 – 4 = 16

16 / 4 = 4

4 / 4 = 1

————-

20 x 5 = 100

100 / 5 = 20

20 + 5 = 25

25 / 5 = 5

5 / 5 = 1

What is five squared?

Good lad!

Are these skills useful for the future? Why?

Thank you.
