Q2Help cranes reach their food using the number line. To reach the worm: 667 – ………. steps = 650. Length of steps: ……….
650655660665670675680685690695700667
The crane stands on 667. The worm is at 650 and the fish is at 700.
Answer

667 – 17 steps = 650

Length of steps: 1

667 – 7 = 660
660 – 10 = 650
7 + 10 = 17
65065566066567067568068569069570066717 steps back
17 steps back take the crane to the worm.
Q3To reach the fish: 667 + ………. steps = 700. Length of steps: ……….

The crane stands on 667. The worm is at 650 and the fish is at 700.
Answer

667 + 33 steps = 700

Length of steps: 1

667 + 3 = 670
670 + 30 = 700
3 + 30 = 33
65065566066567067568068569069570066733 steps on
33 steps forward take the crane to the fish.

The second number line. The crane stands between 770 and 775.
Answer

The crane stands on 773.

773 – 23 steps = 750

Length of steps: 1

773 – 3 = 770
770 – 20 = 750
3 + 20 = 23
75075576076577077578078579079580077323 steps back
23 steps back take the crane to the worm.
Q5To reach the fish: ………. + ………. steps = 800. Length of steps: ……….
750755760765770775780785790795800
The second number line. The crane stands between 770 and 775.
Answer

The crane stands on 773.

773 + 27 steps = 800

Length of steps: 1

773 + 7 = 780
780 + 20 = 800
7 + 20 = 27
75075576076577077578078579079580077327 steps on

410 > 400
640 > 400
400 < 505
400 < 830

Any numbers bigger than 400 are right.

100 + 100 + 100 + 100 + 100 + 100 = 600

Six slips with 100 on each make 600.
Q6Are there numbers which can not be made using these slips? Find out.
Six blank paper slips. On each one you may write 100, 10 or 1.
Answer

Yes. A number can be made only if it needs exactly 6 slips.

250 → 2 + 5 + 0 = 7 slips, too many
100 → 1 + 0 + 0 = 1 slip, too few

700, 999 and 55 cannot be made either.

Q7What is the smallest number that can be made?
Six blank paper slips. On each one you may write 100, 10 or 1.
Answer

The smallest number is 6. Write 1 on every slip.

1 + 1 + 1 + 1 + 1 + 1 = 6
111111
Six slips with 1 on each make 6.
