Word Problems

Day 81

1. We’re going to start solving problems with our math facts. We’ll keep playing games too, so we don’t forget the facts!
2. We’re going to figure out the problems together at first.
3. 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 come 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.
4. 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?
• 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 in 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.

2. Let’s see if you remember. Play this quick game.
3. Now look at these clocks. The minute hands are all pointing to the six. That means “thirty minutes.”
4. Find the right time.
5. Choose a game from Math 2 — Subtraction!

Day 117

1. Remember how to count by fives? Watch the video.

2. 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.
3. 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?
4. Now count around the clock again!

Measurements

Day 146

1. Read the centimeter ruler. Only whole centimeters are marked. You are measuring the red line.
2. This ruler looks different. It’s is still a centimeter ruler. The centimeters are marked with a longer line and the number to the left of 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 red 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 3.50 . (It’s kind of like \$0.50 is halfway to a dollar. \$3.50 is halfway between \$3 and \$4.)

2. Go the manipulatives page. Click on Manipulatives and choose “Bears in a Boat.”
3. Each boat holds ten bears. Drag one boat out onto your white board. Fill it up. Now you have ten. How many more bears do you need to make 16? Drag more bears onto the empty part of the board.
4. You have 1 ten and 6 ones.
5. Now make a picture of the number 23. You need two tens, or two boats. (Click on the boats and then click on the minus (-) magnifying glass to make them smaller so there is room.)
6. Make two tens and then add three more bears to make 23.
7. You have 2 tens and 3 ones.
8. Count the tens and ones. Choose numbers up to 59. The blue blocks are in groups of ten. Each tower of blue blocks is 1 ten. You count them 10, 20, 30…

Day 158

1. Count the objects. Count the number of lines of tens. Then count the ones.
2. Count the tens and then the ones.

Day 159

1. Write the number. Choose the right number of tens. Then choose the right number of ones.
2. “Write the value of the tens and ones. For example, in 24 the 4’s value is just 4 (picture 4 blocks), but the 2 is really 2 tens which is 20 (blocks). If the problem underlined the 2, you would write 20. An easier way to do it is to read the number out loud. We say TWENTY – four. The 2 isn’t just a 2, it’s twenty.”

Day 160*

1. Today we are going to separate tens and ones into addition problems. Here are some examples.
• 11 = 10 + 1      It’s just like counting the groups of ten first and then adding on how many ones are left.
• 17 = 10 + 7     Seventeen is one ten and seven ones.
• 25 = 20 + 5    The number twenty-five is two groups of ten (20) and five more ones.
• 34 = 30 + 4
• 75 = 70 + 5
• 81 = 80 + 1
2. Do you think you could do it? Complete this worksheet (tens and ones expanded form).

Day 161

1. Watch this presentation on adding and subtracting tens. It will play automatically. You don’t need to turn the pages. It will talk to you too, so make sure you have the volume on.
2. Go to this game page. Before you play the game, follow my instructions.
3. Drag a stack of ten blocks onto the board. It should say 10. Do you see it?
4. Drag more stacks of ten blocks onto the board and watch the number change. You are adding tens.
5. Now take the ten stacks away, one at a time, and watch the number change. You are subtracting tens.
6. Now you play that game if you like.

Day 162*

1. *Print out all four worksheets. Today you will do Adding and Subtracting 10s, Worksheet 1.

Day 163

1. Do worksheet 2 that you printed out on Day 162. (If you want the answer sheet to check the answers when you are finished, use the link on Day 162.)

Day 164

1. Do worksheet 3 that you printed out on Day 162.  (If you want the answer sheet to check the answers when you are finished, use the link on Day 162.)

Day 165

1. Do worksheet 4 that you printed out on Day 162.   (If you want the answer sheet to check the answers when you are finished, use the link on Day 162.)

Day 166*

1. When you add ten to a number, you just have to add 1 to the number in the tens spot.
2. 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 .

Day 167*

1. Print out page 89 and complete it. (It’s page 9 of the pdf.)

Day 168*

1. Watch this presentation on subtracting tens.
2. Complete this worksheet on subtracting tens (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.)

Day 169*

1. Print out this adding page. 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. 90 + 50 = ?
• 9 tens plus 5 tens
• 9 + 5 = 14
• 14 tens is 140
• 90 + 50 = 140

Day 170*

1. *Complete this subtraction worksheet (Subtracting Tens part 2). It’s just like Day 169 but with subtraction. Here’s one example.
• 130 – 80 = ?
• 13 tens – 8 tens = ?
• 13 – 8 = 5
• 13 tens – 8 tens = 5 tens
• 130 – 80 = 50

Day 171**

1. Watch this presentation on subtracting tens and ones.
2. *Try some. Complete this worksheet (subtracting 2 digits no regrouping).
3. Next you are going to do an easier worksheet. There is no ten in the bottom number, so you only need to subtract the ones.
4. Here is an example.
5. 46 – 3 = ?
6. 6 ones – 3 ones = 3 ones
7. You aren’t taking away any tens, so there are still 4 tens.
8. The answer is 4 tens and 3 ones or 43.
9. *Complete the worksheet (subtracting 1 digit no regrouping).

Day 172**

1. Watch this presentation on adding tens and ones.
2. And with adding nothing in the tens?
3. 46 + 2 = ?
4. 6 ones + 2 ones = 8 ones
5. 4 tens + no more tens = 4 tens
6. The answer is 4 tens and 8 ones. That’s 48.
7. 46 + 2 = 48
8. Complete these worksheets on adding tens and ones.
9. Worksheet 1: addition with 1 digit
10. Worksheet 2: adding with 2 digits

Day 173**

1. Complete these worksheets. You need to pay attention! Some are + and some are -. If you don’t pay attention, you will get some wrong. Make sure you subtract when it says minus. Make sure you add when it says plus.

Day 174

1. We’re going to try one more thing before the end of the year. You are almost there!
2. Watch this presentation on adding tens and ones.
3. Watch this video on adding this way. Stop around 5:40 when it says “to stop and work on your worksheet.” (You don’t have a worksheet!)
