3. Take the test.  This will only let you do a certain number of problems before asking about an account.  You do not need to make an account.  Just stop once it asks you about an account.

Day 5*

1. *Label the even numbers based on the numbers already on the line.  Use the numbers that are there to figure out the missing numbers in the pattern.  Check your answers.
2. Make numbers. Drag one of those big squares of blocks onto the work mat. What number does it say? 100! There are 100 blocks in that square. It’s 10 stacks of 10 blocks all put together. Make the numbers: 142 and 375. Now you are using hundreds, tens and ones.
3. Make numbers. You are using hundreds, tens and ones. Make a big number. Do you see the hundreds, tens and ones? Click on the button to see them all put together. Click on “new” and make another big number.

Day 6*

xtramath — If you haven’t yet, go to this site every day until you know all of your addition and subtraction facts fast! Stop when you get to multiplication. (Parents: If this isn’t coming easily for your child, you can slow it down. Click on parent/teacher and log in. Choose the child’s tab. Choose Change Program. Choose 6 second addition. When it’s mastered, you can change to subtraction, etc.)

1. *What numbers come before and after? Which number is the hundreds?  Check your answers.
2. Click to play “10 more”. It will tell you a number. Add 10. Remember how? Add 1 to the ten’s place. It’s easy on the chart. Just look down one row because each row has ten numbers. When you find the right answer, click on “next” to get your next number to find. When this is easy for you, go on to number three (below).
3. Play again.  This time click “11 more“. That’s adding 10 and adding 1. Now you will add 1 to the tens and 1 to the ones. What happens when you add 1 to 9? Do you remember? It’s easy on the chart. Just move down one row to add 10 and over one spot to add 1.

Day 7*

2. You are going to complete a worksheet, but before you start, I want you to look at the first problem. You are going to subtract 20 from 100. We’re going to do it together.
• First you’ll subtract the ones straight down. Zero minus zero is zero. You can write zero in the answer spot under the zeros in the ones column.
• What’s left? Draw a box around the 10 left in 100.
• Now you have ten minus two left. You know the answer to that. What’s ten minus two?  (answer: 8)
• Write 8 in the tens spot in the answer.
• *Complete the worksheet. Each time draw a box around the ten in the problem. When you need to borrow more ones in order to subtract, you can cross off the ten and make it a nine. Then like normal you take those ten and move them into the ones column.  Check your answers.
Day 29*
1. *Use your worksheet and subtract the money, like you are making change. (You can ignore the decimal points. For example, the first one is 65 cents minus 21 cents. 65 – 21 = 44.  That’s 44 cents. You write that as \$0.44 .  For all of your answers you will write \$0. and then the answer to your subtraction problem. I already gave you the first answer, so you are already on your way!
Day 30*

Day 32*

xtramath

1. Watch this video on rounding.
2. 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 “go.” 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 “go.” Find 27. Is it closer to 20 or 30?
• 2 –> Is it closer to 0 or 10?
3. Try rounding to the nearest ten.

• 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 we need to change the number on the left to one more. The 4 becomes a 5.
• 461 –> 500   Which is 461 closer to, 400 or 500?
3. Watch this video again, just for the first 32 seconds.
4. Round to the nearest hundred.

4. Remember: the hour is not eight yet. It’s still five minutes before the hour hand will reach the eight.
5. Do you see that there are just five minutes until eight o’clock?
6. When we talk about time until the hour, we count by fives backwards. At the 11 there are just five minutes until the hour. At the 10 there are ten minutes until the hour.
7. Make the clock say “ten minutes to nine.” What does the digital clock say?  (answer  8:50)
8. Remember: It’s not nine o’clock yet. There are still ten minutes before the hour hand reaches the nine.
9. If you got it wrong, fix the clock hands.
10. Make the clock say “twenty minutes until ten.”  Count by fives backwards. The 11 is five, the 10 is ten, the 9 is 15…  What does the digital clock say when you make the hands say “twenty minutes to ten?”  (answer  9:40)

• You don’t need to know the names of all of those properties, but it’s good to know these things. Read below.
• Multiplication is adding over and over again. 5 times 2 is 5 + 5, 5 times 3 is 5 + 5 + 5, 5 times 4 is 5 + 5 + 5 + 5, That’s like counting by fives 4 times.
• If I put five books on each shelf and there were four shelves, I would have 5 + 5 + 5 + 5 books. 5 x 4 = 20
• Anything zero times is zero. A million times zero is zero. If I gave you a million dollars zero times, you would have zero dollars.
• Anything one time is itself. 8 times 1 is 8. If I give you eight pieces of candy one time, you would have eight pieces of candy.
• 3 times 2 is the same as 2 times 3 (just like addition). If I gave you 3 M&Ms two times, you would have 6. If I gave you 2 M&Ms three times, you would have 6. If you don’t believe me, go ask for some chocolate chips to practice with. Give 3 two times and 2 three times and see if it’s the same amount.  2 x 3 = 3 x 2 = 6
2. Learn that any number times zero is zero.
