Skip counting answers: exercises 1 to 10

Exercise 1 – Count by 5s

Add 5 each time: 35, 40, 45, then 45 + 5 = 50 and 50 + 5 = 55.

50 and 55

35, 40, 45, 50, 55, 60.

Exercise 2 – Count by 10s

Add 10 to 140 to get 150. Add 10 to 150 to get 160.

150, 160

Exercise 3 – Count by 100s

Add 100 each time: 400 + 100 = 500 and 500 + 100 = 600. Then 600 + 100 = 700 fits.

500, 600

Exercise 4 – Next by 5s

\(275 + 5 = 280\)

280

Exercise 5 – Missing number

\(490 + 10 = 500\), and 500 + 10 = 510 checks.

500

Exercise 6 – Count back by 10s

Take away 10 each time: \(350 – 10 = 340\) and \(340 – 10 = 330\).

340, 330

Exercise 7 – Count the jumps

Count the arcs: 5, 10, 15, 20, 25, 30. That is 6 jumps.

\(6 \times 5 = 30\)

6 jumps

Exercise 8 – Compare two numbers

The hundreds are the same (2). Compare the tens: 4 tens is less than 5 tens.

\(245 < 254\)

Exercise 9 – Compare close numbers

600 has 6 hundreds. 599 has only 5 hundreds.

\(600 > 599\)

Exercise 10 – Same number

The hundreds, tens and ones are all the same.

\(318 = 318\)

Exercises 11 and up

Exercise 11 – Compare with blocks

Both have 4 hundreds. The top has 1 ten and the bottom has 2 tens.

\(412 < 421\)

1 ten is less than 2 tens, so 412 is less than 421.

Exercise 12 – Write a sentence

706 has 7 hundreds and 670 has 6 hundreds.

\(706 > 670\)

Exercise 13 – Order the numbers

842 has the most hundreds, so it is greatest. 482 and 428 both have 4 hundreds. Compare the tens: 2 tens is less than 8 tens.

So 428 < 482 < 842.

428, 482, 842

Exercise 14 – Greatest number

95 has no hundreds, so it is least. 509 and 590 both have 5 hundreds. 9 tens is more than 0 tens.

590

Exercise 15 – Count the nickels

Count by 5s: 5, 10, 15, 20, 25, 30, 35, 40.

\(8 \times 5 = 40\)

40 cents

The 8th nickel brings the total to 40 cents.

Exercise 16 – Boxes of paper

Count by 100s: 100, 200, 300, 400, 500, 600, 700.

700 sheets

Exercise 17 – Cross 300

Add 10 each time. 280 + 10 = 290. 290 + 10 = 300. 300 + 10 = 310. 310 + 10 = 320.

290, 300, 310

The hundreds digit changes from 2 to 3 at 300.

Exercise 18 – Find the rule

Each number is 5 more than the one before it.

The rule is count by 5s. Next: 130 + 5 = 135.

Count by 5s; 135

Exercise 19 – Stamp collections

Both have 3 hundreds. Compare the tens: 5 tens is more than 4 tens.

\(354 > 345\)

Aisha has more stamps.

Exercise 20 – Jumping jacks

List the numbers: 150, 160, 170, 180, 190. The fifth number is 190.

190

Exercise 21 – Mystery digit

Try tens digits. 462 is not greater than 463, because 6 tens and 2 ones is less than 6 tens and 3 ones.

472 is greater than 463 because 7 tens is more than 6 tens.

Exercise 22 – Count back by 100s

Take away 100 each time: \(900 – 100 = 800\) and \(800 – 100 = 700\). Then 700 – 100 = 600 checks.

800, 700
