## HMH Into Math Grade 2 Module 6 Lesson 3 Answer Key Identify and Extend Number Patterns

I Can complete a pattern that counts by tens or hundreds.

How can you show the number of ladybugs in the rose garden?

Read the following: There are 200 ladybugs on the roses in the garden. 10 more ladybugs land on the roses. How many ladybugs are there now? Write the number. Which digit changed? Write the place the digit is in. Then 10 more ladybugs land on the roses. How many ladybugs are there now? Write the number. Which digit changed? Write the place the digit is in.

Explanation:
Given that there are 200 ladybugs on the roses in the garden and 10 more ladybugs land on the roses. So the number of ladybugs are there now is 200+10 which is 210 ladybugs. Here the tens place was changed and 10 more ladybugs landed on the roses. So the number of ladybugs is 210+10 which is 220. The tens place was changed.

Build Understanding

Mr. Coates is learning to knit. He knits 720 stitches. He starts a new row every 10 stitches. Use the hundred chart.
A. How many stitches are at the end of the next row?
____ stitches

The number of stitches will be 730 stitches.

Explanation:
Given that Mr. Coates knits 720 stitches and he starts a new row every 10 stitches. So the number of stitches will be 720+10 which is 730 stitches.

B. Count by 10s to fill in the missing numbers in the chart.

C. Start at the last number you filled in. What number is 10 less?
___________

780.

Explanation:
The last number filled is 790 and the number less than 10 is 790-10 which is 780.

D. Look at the tens place. Complete the pattern.
390, 380, 370, ___, ___, ____, ____
621, 631, 641, ___, ___, ____, ____

390, 380, 370, 360, 350, 340, 330.
621, 631, 641, 651, 661, 671, 681.

Explanation:
Here, the pattern followed count back of 10, so the pattern is 390, 380, 370, 370-10= 360, 360-10= 350, 350-10= 340, 340-10= 330.
Here, the pattern followed count of 10, so the pattern is 621, 631, 641, 641+10= 651, 651+10 = 661, 661+10 = 671, 671+10 = 681.

E. Look at the hundreds place. Complete the pattern.
100, 200, 300, ___, ___, ____, ____
805, 705, 605, ___, ___, ____, ____

100, 200, 300, 400, 500, 600, 700.
805, 705, 605, 505, 405, 305, 205.

Explanation:
Here, the pattern followed count of 100, so the pattern is 100, 200, 300, 300+100 = 400, 400+100 = 500, 500+100 = 600, 600+100 = 700.
Here, the pattern followed countback of 100, so the pattern is 805, 705, 605, 605-100 = 505, 505-100 = 405, 405-100 = 305, 305-100 = 205.

Turn and Talk Which digit changes as the numbers increase by 100? Which digit changes as the numbers decrease by 100?
For both increasing and decreasing the hundreds place is only changing.

Step It Out

1. If Make a pattern of numbers that shows 100 more.
A. Draw a number greater than 100, but less than 1,000.

The number is 200.

B. Draw a number that is 100 more.

The number is 300.

C. Draw a number that is 100 more than your last number.

The number that is 100 more than your last number is 300+100 which is 400.

D. Write the numbers in your pattern.
___, ___, _____

The pattern is 200, 300, 400.

Question 1.
529 ants live in a colony. 100 more ants hatch every week. Complete the pattern.
529, ___, ___, ___, _____

529, 629, 729, 829, 929.

Explanation:
Given that 529 ants live in a colony and 100 more ants hatch every week. So the pattern will be 529, 529+100 = 629, 629+100 = 729, 729+100 = 829, 829+100 = 929.

Question 2.
Use Structure There are 270 oranges at the grocery store. Each shopper buys 10 oranges. Complete the pattern to show how many oranges there are after each shopper buys 10 oranges.
270, ___, ___, ___, ____

270, 280, 290, 300, 310.

Explanation:
Given that there are 270 oranges at the grocery store and each shopper buys 10 oranges. So the pattern will be 270, 270+10 = 280, 280+10 = 290, 290+10 = 300, 300+10 = 310.

Attend to Precision Complete the pattern.
