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-
What will be the value of the finished Cent Sign?

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.

Day 12: Which One Doesn't Belong?

Day 12:  Which One Doesn't Belong?

K-2 Directions:  Look at the 4 shapes made with cubes below.  One of them is different from the others.  When you figure out which one doesn't fit in, tell someone you're home with which one it is.  Make sure you tell them why it doesn't belong.  Post your thoughts in the comments below.  (Shapes can be numbers 1-4 clockwise from the top left to make commenting easier)



K-2 Challenge:  After finding one shape that doesn't belong, try to find a different one that doesn't belong.  Tell someone you're home with the reason why it doesn't belong.  It should be a different reason than the first one!

3-5 Directions:  Look at pictures of money below.  They all have something in common, but you can also justify why one of them doesn't belong with the others.  When you figure out which one doesn't fit in, tell someone you're home with which one it is.  Make sure you tell them why it doesn't belong. Then, using a different reason, try to find a different money amount that doesn't belong.  Once you have, tell someone in your house the new reason why that image doesn't belong.  Post your thoughts in the comments below.  



3-5 Challenge:  Come up with a reason why each of the 4 amounts of money doesn't belong in the group with the others!  Tell someone you're home with and post thoughts in the comments section below.
