Day 18 - Which One (from your house) Doesn't Belong?

Day 18:  Which One (from your house) Doesn't Belong?

Directions: Like earlier this week, it's your job to come up with a "Which One Doesn't Belong?", but this time it is with things around your house.  Find 4 things and figure out why one doesn't belong and then take a picture.  You can email the picture to jpera@bpsk12.org and they will be posted tomorrow.  I put an example below.  Can you figure out why one of the dice doesn't belong, then come up with a different reason for a different one?  Looking forward to seeing what you come up with!

Day 15 - Make Your Own "Which One Doesn't Belong?"

Day 15:  Make Your Own "Which One Doesn't Belong?"

Directions: Today it's your turn to help make a "Which One Doesn't Belong?".  Instead of having 4 options like normal, there are only 3 today.  It's your job to add in a 4th one that doesn't belong OR makes one of the original three not belong and tell us why in the comments below.  Your answers need to be an addition expression (K-2) or subtraction expression (3-5).

K-2:

2+43+3
4+3?

3-5:  

14-616-8
18-9?

Challenge:  Once you come up with a 4th option that doesn't fit in, try to come up with a NEW one that makes the other three not fit in.  See an example below:

5
8
9
?

#1 - If I replace the ? with the number 11, 8 doesn't fit in because it's the only even number.


#2 - If I replace the ? with the number 16, 5 doesn't fit in because you can't use repeated addition to get to the number 5.
(2 + 2 + 2 + 2 = 8, 3 + 3 + 3 = 9, 4 + 4 + 4 + 4 = 16)

#3 - If I replace the ? with the number 13, 9 doesn't fit in because 5 + 8 = 13.

Day 14- Coin Estimation

Did you know that 70% of your life you actually need to estimate instead of calculate the correct answer?  That is more than 1/2 of the time.  Here is a great chance to practice this important skill.


For each one- Put your estimation and reasoning in the comment box below with a label.  Do better than I just guessed for your reasoning.  For example, " Pennies= ____ cents I know this because ...."  Try more than one!  Try the challenge!  On Monday we will reveal the answers and who is the closest for each grade span.

Grade K-1-
What is the value of the roll of pennies?  

Grade 2-3-
What is the value of the roll of Nickels? Dimes?


Grade 4-5-
What is the value of the roll of Quarters?

Challenge-

Day 13 - Play a Card Game

Play a card game with someone in your house and post a comment about which one you played and  how it went.

K-1 Activity:

Tens Go Fish:  



You need a deck of ordinary playing cards with the face cards and 10's removed.
1. Each player is dealt 5 cards.
2. Each player looks for pairs from his or her cards that make 10.  Players put down the pairs of cards that make 10, and they draw new cards to replace them.
3. Players take turns asking each other for a card that will make 10 with a card in their own hands.
If a player gets the card he or she asked for, he or she puts the pair down and picks a new card from the deck.
If a player does not get the card that he or she asked for, the player must "Go Fish" and pick a card from the deck.

If the new card makes 10 with a card in the player's hand, he or she puts the pair of cards down and takes another card.
If a player runs out of cards, the  player picks two new cards.
A player's turn is over when no more pairs can be made that make 10.
The game is over when there are no more cards.

Gr. 1-2 Activity:

Make Ten Card Game:


1.  Remove the face cards from a deck of cards and place the deck face down on a table.
2.  Each player chooses 5 cards from the top of the deck and puts the cards in front of them.
3.  The first player uses the 5 cards in front of him/her to make 10 in as many ways as possible and writes them down.  For example, if I had the cards 9,1,3,2,4.  I could write 9+1= 10, 4+3+2+1=10, or 9+4-3=10.
4.  After making as many equations as possible, the player sets aside used cards and play passes to the next player.
5.  Play continues with players refilling their 5 cards at the beginning of each round.
6.  Whoever used the most cards by the end of the deck is the winner.

Gr. 3-5 Activity:

Oh no!  99:  (2-4 players:
