Word Problems
Lesson 41
 We’re going to start solving problems with our math facts. We’ll keep playing games too, so we don’t forget the facts!
 We’re going to figure out the problems together at first.
 Let me give you an example of what a word problem is. Usually you do your math like this: 6 + 4 = ? Let’s make that into a word problem.
 Let’s say you have six people in your family. Another family with four people in it comes over for dinner. How many people will be sitting at the table?
 That’s a word problem. You need to figure out the answer, so you know how many chairs and plates you’ll need to set up.
 How do you figure it out? You have 6 people plus 4 more come. That’s 6 plus 4. 6 + 4 = 10. That’s your answer.
 Now your turn. Here’s the word problem.
 Ned rode his bike 7 miles to the library.
He took a shortcut on the way home which was only 5 miles long.
How many miles did Ned ride altogether?  I’m going to give you a hint. When a problem says altogether, you are going to add to find your answer. Before we add, let’s start with a picture.
 Take a piece of paper. Draw Ned on one side. Draw a library on the other side (it can just be a square.) Put your finger on Ned. Your finger is Ned. Now move your finger up and over and to the library. How far did Ned go so far? How many miles? Read the problem to find out. (answer: 7 miles) Write the number on the paper.
 Now move your finger straight back home. How far did Ned go to get back home? Look at the problem and find the number. (answer: 5 miles)
 Leave a space next to the seven and then write the number.
 Now let’s do it altogether. Put your finger on Ned. Go 7 miles to the library and 5 miles back home. How far did Ned go altogether?
 He went 7 miles plus 5 miles more. Write a plus sign between the 7 and the 5.
 What’s the answer? Go type it in and click on “Check.” Then click on “Show Answer.”
 Now, he didn’t go 12 centimeters or 12 feet. He went 12 miles. In a word problem it is VERY important to label your answer, meaning write the word that you are talking about (like miles for this problem).
 You solved your first word problem. Way to go! Now you can play a game.
 Ned rode his bike 7 miles to the library.

Lesson 42
 Here’s your new word problem.
 Anne ate 6 cookies.
Samantha ate 4 more cookies than Anne.
How many cookies did Samantha eat?
 Anne ate 6 cookies.
 Draw a picture or use Legos as cookies. You need 6 cookies. Draw 6 cookies or lay out 6 “cookies.”
 Who ate that many cookies? (answer: Anne)
 Who ate the most cookies? Read the problem carefully to find the answer. (answer: Samantha)
 The problem tells us that Samantha ate more cookies than Anne.
 How many cookies did Samantha eat? How do we figure it out? We know she ate 6 cookies, just like Anne, but then she ate more. How many more? (answer: 4 more)
 Add 4 more cookies to your drawing or Lego collection.
 How many cookies did Samantha eat? Write the number equation. That means write the problem with numbers and no words. (answer: 6 + 4 =)
 Type in your answer and check it. Type in the number and the label, the word you are talking about (cookies this time). First you will have to click on the arrow to change it to the second problem (2/5). That means second out of five problems.

 Henry gave 5 stickers to his younger brother.
Now he only has 9 stickers.
How many stickers did Henry have at first?
 Henry gave 5 stickers to his younger brother.
 What should we do first? Let’s draw a picture.
 Draw two people. Draw one stick person on one side of the page and another stick person on the other side of the page.
 Draw 5 stickers under one and 9 stickers under the other.
 How many stickers does Henry have now? (answer: 9 stickers)
 Before, he had those nine stickers, plus all of the stickers he gave his brother. Write this word problem as an equation, as a number problem. Don’t look at the answer until you’ve written the problem with numbers instead of words. (answer: 9 + 5 = )
 How many stickers did Henry have at first, before he gave any away? Click on the arrow to find the third problem (3/5) and then enter your answer with a number and a word label. The word label for this problem is stickers.

Lesson 44
 Here’s your next word problem.
 Derek and Larry have 15 books together.
6 of the books belong to Derek.
How many books does Larry have?
 Derek and Larry have 15 books together.
 What do we do first? (answer: Draw a picture.)
 Draw a picture of 15 books. (You can just make a line for each book. It doesn’t have to be a pretty picture.) Or, you can get out 15 Legos and pretend they are the books.
 Your fifteen books are Derek’s and Larry’s. Right now they are all together in one big pile.
 Now, look at the problem. How many of the books are Derek’s? (answer: 6 books)
 Count out six Legos and put them in a separate pile. Or, circle six books in your picture. Those are the ones that belong to Derek.
 Who do the rest of the books belong to? (answer: Larry)
 So, how many books does Larry have? Count them up. That’s the answer.
 But how do we get that with a number problem? What kind of problem is it when you have a lot and then take some away? Is it an addition problem or a subtraction problem? (answer: subtraction)
 Write this word problem as a number problem. Write the equation. Don’t look until you wrote it down. (answer: 15 – 6 = )
 How many books does Larry have? Click on the arrow to find the fourth problem (4/5) and then enter your answer with a number and a word label. What’s the word label for this problem? (answer: books)
 Were you right? Did you write 9 books?

5 clowns were wearing striped pants.
How many more clowns were wearing polka dot pants?
 11 clowns were wearing polka dot pants.
 What do you do first? (answer: Draw a picture. Draw the striped pants right underneath the polka dot pants.)
 This problem is different than others you have done. It asks, “How many more clowns were wearing polka dot pants?” It’s asking what’s the difference between the number of polka dot clowns and the number of striped clowns.
 Look at the picture. Draw a line from each striped pants to a polka dot pants. How many polka dot pants extra are there? How many don’t have matches? That’s how many more there are. How many? (answer: 6 clowns)
 How do we write that with numbers as an equation? Is it addition or subtraction? Write the equation before you peek at the answer. (answer: 11 – 5 = 6)

Lesson 54
 We’re going to add and subtract tens.
 3 apples + 5 apples = 8 apples, right?
 3 tens + 5 tens = 8 tens
 3 tens = 30 and 5 tens = 50
 30 + 50 = 80
 We add the ones: zero plus zero is zero.
 We add the tens: 3 + 5 = 8.
 What would 90 – 40 be?
 9 apples – 4 apples = 5 apples.
 9 tens – 4 tens = 5 tens
 90 – 40 = 50
 We subtract the ones: zero minus zero is zero.
 We subtract the tens: 9 – 4 = 5.
 Add tens.

 We add the ones: zero plus zero is zero.
 We add the tens: 9 + 5 = 14.
 What would 130 – 80 be?
 13 apples – 8 apples = 5 apples.
 13 tens – 8 tens = 5 tens
 130 – 80 = 50
 We subtract the ones: zero minus zero is zero.
 We subtract the tens: 13 – 8 = 5.

Lesson 73
 Remember how to count by fives? Watch the video.
 Now look at this clock face. Each of those big numbers stands for an hour. If the hour hand is pointing to the two, it is two o’clock. If it is after the two (but not to the 3 yet) then it is 2 and some minutes. Let’s figure out how many minutes.
 Point to each number as you count by fives. Point to the 1 and say “five.” Point to the 2 and say “ten.” It takes five minutes for the minute hand to move from one number to the next, so we count by fives when we are counting minutes. Count by fives all the way around the clock. When you get to the 11 you should be at 55 minutes. Did you count correctly?
 Now count around the clock again!

Adding and Subtracting Tens
 Complete the worksheet on adding and subtracting tens.
 You’ve seen this before. The ones place only has zero.
 Check your answers.
 When you add ten to a number, you just have to add 1 to the number in the tens spot.
 Watch this presentation on adding tens. It will play automatically and talk to you.
 40 + 10 = 50 You start with 4 tens. That’s 40. Then you add 1 ten. 4 tens + 1 tens = 5 tens. 5 tens is 50.
 35 + 10 = 45 The number 35 has 3 tens. Then you add 1 ten. 3 tens + 1 ten = 4 tens. The ones stay the same. We added nothing to the ones, so the answer is 45.

 *Complete the worksheet on subtracting tens. It’s what you did yesterday. Here are some examples.
 20 – 10 = 10 (2 tens – 1 ten = 1 ten)
 23 – 10 = 13 (2 tens – 1 ten = 1 ten You aren’t taking away any ones, so that number stays the same.)
 47 – 10 = 37
 50 – 20 = 30 (5 tens – 2 tens = 3 tens)
 56 – 20 = 36 (5 tens – 2 tens = 3 tens You aren’t taking away any ones, so that number stays the same.)
 Check your answers.
Lesson 84*
 *Look at your worksheet for today. It’s only adding but it uses bigger numbers. It’s the same thing, though. You can do it. Let’s look at a couple of examples before you start.
 40 + 80 = ? 4 tens + 8 tens = ?
 What is 4 plus 8? (answer: 12)
 So the answer is 12 tens. How do you write that?
 Well, how do you write 6 tens? You add a zero and write 60.
 How do you write 4 tens? You add a zero and write 40.
 How do you write 12 tens? You add a zero and write 120.
 Let’s try one more. 92 + 50 = ?
 9 tens plus 5 tens and 2 ones plus 0 ones.
 9 + 5 = 14 and 2 + 0 = 2
 14 tens is 140
 92 + 50 = 142

 Now choose level 2 and measure to the half centimeter. The centimeters are marked with a longer line and the number above it. In the middle of each centimeter is a shorter line. That’s halfway between. That’s a half a centimeter from the last marker. If the line stops at a middle line, then the length is the number of centimeters before it plus one half. If the red line stopped at a half a centimeter more than three, then the answer would be 3.5. (It’s kind of like $0.50 is halfway to a dollar. $3.50 is halfway between $3 and $4.)

 The middle line is the next longest. That marks half an inch.
 The other two lines on either side mark a quarter of an inch, 1 out of 4 parts of the inch or 1/4, or one quarter.
 If the line stops at the third line on the inch, then that is 3/4 of an inch. Give it a try.

Rounding and EstimationLesson 136
 Estimating means making a good guess as to what the answer is.
 Rounding is one trick we use to figure out what a good guess would be.
 Watch this video on rounding. Here are some examples of rounding to the nearest ten:
 13 –> the number on the right is four or less, so the number on the left stays the same
 10 is the nearest ten
 Look at it on the number line. Click on “done” to close the box. Find 13. Is it closer to 10 or 20? That’s what rounding is. Which number is closer? If it is right in the middle, we round up to the higher number.
 27 –> The number on the right is 5 or more, so the number on the left moves up one.
 30 is the nearest ten
 Look at it on the number line. Click on “done” to close the box. Find 27. Is it closer to 20 or 30?
 2 –> Is it closer to 0 or 10?
 Try rounding to the nearest ten.

 461 –> We are rounding to the nearest hundred. Which number is in the hundreds spot? (answer: 4)
 461 –> When we round this to the nearest hundred, we are asking, “Which is it closer to, 400 or 500?”
 We need to look at the number immediately to the right. Which number is to the right of 4? (answer: 6)
 Is six, 5 or more? (answer: yes)
 Then yes, we need to change the number on the left. The 4 becomes a 5.
