Fill in the blanks with appropriate numbers. a) 2540, 2590, ____, ____, ____, ____ 2540 2590 Six trees in a row. Two of them already carry a number.

2540 2590 Six trees in a row. Two of them already carry a number. First find the jump between the two given numbers. 2590 − 2540 = 50 2590 + 50 = 2640 2640 + 50 = 2690 2690 + 50 = 2740 2740 + 50 = 2790 2540 2590 2640 2690 2740 2790 Six trees in a row. Two of them already carry a number. Why it happens: The tens digit goes up by 5 each time, and 5 tens is 50. So we skip-count in fifties.

Fill in the blanks with appropriate numbers. b) 354, 1354, ____, ____, ____, ____, ____ 354 1354 Seven gates in a row. Two of them already carry a number.

354 1354 Seven gates in a row. Two of them already carry a number. Find the jump first. 1354 − 354 = 1000 1354 + 1000 = 2354 2354 + 1000 = 3354 3354 + 1000 = 4354 4354 + 1000 = 5354 5354 + 1000 = 6354 354 1354 2354 3354 4354 5354 6354 Seven gates in a row. Two of them already carry a number. Why it happens: Only the thousands digit changes — 1, 2, 3, 4, 5, 6. The last three digits stay 354 all the way.

7645 7670 7745 A number line with eight boxes. Three boxes already carry a number. Find the jump between the first two boxes. 7670 − 7645 = 25 7670 + 25 = 7695 7695 + 25 = 7720 7720 + 25 = 7745 matches the printed box 7745 + 25 = 7770 7770 + 25 = 7795 7795 + 25 = 7820 7645 7670 7695 7720 7745 7770 7795 7820 A number line with eight boxes. Three boxes already carry a number. Why it happens: On a number line the jumps are all of one size. The printed 7745 in the middle tells us our jump of 25 is right.

Seven gates in a row. Two of them already carry a number.

Answer

Seven gates in a row. Two of them already carry a number.

Find the jump first.

1354 − 354 = 1000
1354 + 1000 = 2354
2354 + 1000 = 3354
3354 + 1000 = 4354
4354 + 1000 = 5354
5354 + 1000 = 6354

Seven gates in a row. Two of them already carry a number.

A number line with eight boxes. Three boxes already carry a number.

Answer

A number line with eight boxes. Three boxes already carry a number.

Find the jump between the first two boxes.

7670 − 7645 = 25
7670 + 25 = 7695
7695 + 25 = 7720
7720 + 25 = 7745 matches the printed box
7745 + 25 = 7770
7770 + 25 = 7795
7795 + 25 = 7820

A number line with eight boxes. Three boxes already carry a number.

Why it happens: On a number line the jumps are all of one size. The printed 7745 in the middle tells us our jump of 25 is right.
