Application ProblemApplication Problem
The shelter rescued 27 kittens in June. In July, it rescued 11 more. In August, it rescued 40 more.
How many kittens did the shelter rescue during those 3 months?
If 64 of those kittens found homes by August, how many still needed homes?

Concept DevelopmentConcept DevelopmentUse your base ten blocks to show
me 157 on your place value chart. Show me 10 more. Use a sentence frame to describe
adding 10 to 157. 10 more than 157 is 167. 167 is 10 more than 157. What did you do to change 157? Add 10 to the tens place.
![Page 13: More and Less Lesson 5.1:. Place Value On your place value chart, show 6 ones in chips. Write the number below it. What is the number? Show 1 chip in](https://reader036.vdocuments.mx/reader036/viewer/2022062516/56649d745503460f94a54885/html5/thumbnails/13.jpg)
Concept DevelopmentConcept DevelopmentGive me an addition sentence
starting with 157. 157 + 10 = 167 Start with 167 167 = 10 + 157167 = 157 + 10

Concept DevelopmentConcept DevelopmentShow me 157 again on your place
value chart. Show me 100 more than 157. Use a sentence frame to describe
adding 100 to 157. 257 is 100 more than 157. 100 more than 157 is 257. What did you do to change 157? We added another hundred. We added 1 hundred to 1 hundred.

Concept DevelopmentConcept DevelopmentBe specific. Where did you add the
hundred? To the hundreds place. Give addition sentence starting
with 157. 157 + 100 = 257Start with 257257 = 100 + 157257 = 157 + 100

Concept DevelopmentConcept DevelopmentTalk with your partner. Use place value
language to explain what you understand about 10 more, 10 less, 100 more, and 100 less.
We already knew about 10 more and 10 less, and now 100 acts the same.
10 less and 100 less is the same as taking away 10 or 100.
We have to subtract and add the same units, so the tens place changes when we add or subtract 10. The same for the hundreds place.

Concept DevelopmentConcept DevelopmentListen as I say a number pattern.
Raise your hand when you know the more or less rule for my pattern.
For example, if I say, “121, 131, 141, 151, 161,” you say, “10 more.” Wait for my signal.

Concept DevelopmentConcept DevelopmentI’ll write a series of numbers on the
board. In your notebooks, write the rule and the next three numbers.
The rules are + 10, ─ 10, + 100, and ─ 100.
Turn your notebook over when you have written your answer. Wait until I say, “Show me.”

show how we skip counted. Let’s try this.

Concept DevelopmentConcept DevelopmentIn the last unit, we used this
simplifying strategy; we called it the arrow way.
Talk to your partner about how this example is the same as and different from the ones we’ve done before.
Instead of ones and tens, this is tens and hundreds.
It’s just different place values.
