Step It Out
1. Look for patterns.
A. Count by fives.
45, 50, 55, ___, ___, ___, ___
165, 170, 175, ___, ___, ___, ___
Answer:
The pattern will be 45, 50, 55, 60, 65, 70, 75.
The pattern will be 165,170,175,180,185,190, 195.
Explanation:
Given to count by fives, so 45, 45+5 = 50, 50+5 = 55, 55+5 = 60, 60+5 = 65, 65+5 = 70, 70+5 = 75. So the pattern will be 45, 50, 55, 60, 65, 70, 75.
Given to count by fives, so 165, 170, 175, 175+5 = 180, 180+5 = 185, 185+5= 190, 190+5 = 195. So the pattern will be 165,170,175,180,185,190, 195.
B. Count by tens.
530, 540, 550, ___, ____, ___, ____
670, 680, 690, ___, ___, ___, ___
Answer:
The pattern will be 530, 540, 550, 560, 570, 580, 590.
The pattern will be 670, 680, 690, 700, 710, 720, 730.
Explanation:
Given to count by tens, so 530, 540, 550, 550+10 = 560, 560+10 = 570, 570+10 = 580, 580+10 = 590. So the pattern will be 530, 540, 550, 560, 570, 580, 590.
Given to count by tens, so 670, 680, 690, 690+10 = 700, 700+10 = 710, 710+10 = 720, 720+10 = 730.
So the pattern will be 670, 680, 690, 700, 710, 720, 730.
C. Count by hundreds.
100, 200, 300, __, ___, __, ___
300, 400, 500, __, ___, __, ___
Answer:
The pattern will be 100, 200, 300, 400, 500, 600, 700.
The pattern will be 300, 400, 500, 600, 700, 800, 900.
Explanation:
Given to count by hundreds, so 100, 200, 300, 300+100 =400, 400+100 = 500, 500+100 = 600, 600+100 = 700. So the pattern will be 100, 200, 300, 400, 500, 600, 700.
Given to count by hundreds, so 300, 400, 500, 500+100 = 600, 600+100 = 700, 700+100 = 800, 800+100 = 900. So the pattern will be 300, 400, 500, 600, 700, 800, 900.
Turn and Talk Is it faster to count by tens or by hundreds? Explain.

Question 1.
Xavier is on page 170 of his book. He reads 10 pages every day for the next three days. What page will he be on at the end of the three days?
170, ___, ___, ____
Xavier will be on page ___
Answer:

Question 2.
Count by fives.
285, 290, 295, __, ___, ___, ___
Answer:
The pattern will be 285, 290, 295, 300, 305, 310, 315.
Explanation:
Given to count by fives, so 285, 290, 295, 295+5 = 300, 300+5 = 305, 305+5 = 310, 310+5 = 315. So the pattern will be 285, 290, 295, 300, 305, 310, 315.

There are ___ trees planted.
Answer:
There are 800 trees are planted.
Explanation:
Given that a new forest has 200 trees and workers plant 100 more trees every day for six days. So the count will be 200, 200+100 = 300, 300+100 = 400, 400+100 = 500, 500+100 = 600, 600+100 = 700, 700+100 = 800. So there are 800 trees are planted.
Question 4.

Answer:
Question 5.
Use Repeated Reasoning Count by tens.
60, 70, 80, ___, ___, ___, ____
Answer:
60, 70, 80, 90, 100, 110, 120.
Explanation:
Given to count by tens, so 60, 70, 80, 80+10 = 90, 90+10 = 100, 100+10 = 110, 110+10 = 120. So the pattern will be 60, 70, 80, 90, 100, 110, 120.
Question 6.
Count by fives.
735, 740, 745, ___, ___, ___, ____
Answer:
The pattern will be 735, 740, 745, 750, 755, 760, 765.
Explanation:
Given to count by fives, so 735, 740, 745, 745+5 = 750, 750+5 = 755, 755+5 = 760, 760+5 = 765. So the pattern will be 735, 740, 745, 750, 755, 760, 765.
