A Whole Lotta Math Goin' On!

Wow!  We have been busy, but we have been having so much fun, 
I don't think the kids realize that we have learning lots too!

First of all, I have a couple of great books to share with you.
My new favorite book is
Developing Number Sense Grades 3-6!

 I don't know about your kiddos, but mine coming into 4th grade
really struggle with number sense.
This book is awesome!  Last week I introduced a game called

Get to 1000.

Each pair of students get 1 die.
Players take turns rolling the die.
On each roll, each player decides separately whether he or she
wants to multiply the number by 1, 10, or 100.
Each player records the resulting product on a piece of paper.
Players continue to roll, multiply, and record their products until they each have 
ten products on their paper.  (Each player will have rolled 5 times.)
Each player finds the sum of his or her products.
The one whose final score is closer to 1000, whether over or under,
is the winner.
The best part of this book though is that there is a writing piece to each activity.
Here are some pics of my kiddos and their write-ups...

We played this game several times last week and they are getting better at it.

Last week we also did an activity that I found at The Teaching Thief.
First we brainstormed what they knew already about 
multiplication and created this anchor chart.

Then we made these multiplication concept posters.  
Just like Amanda said, stickers and food did the trick!

Here are a few of their masterpieces...

Today I taught them a new game, 
Oh, no!  99!

They loved that they got to use playing cards!
For this activity you need a deck of playing cards for each pair.
I got mine at Dollar Tree, 2 decks for a dollar!

It goes like this...
Aces:  add 1
Jacks:  subtract 10
Queens:  wild cards that can represent any other card in the deck
Kings:  add zero
All others (2-10):  add their face value

One player shuffles the cards and deals 4 cards to each player.
The rest of the cards become the draw pile.
Players take turns playing one card at a time, adding or subtracting 
the value of their card to or from their jointly accumulating score.
Each time a player plays a card, he or she must replace it 
with the top card on the draw pile.
Play continues until one player forces his partner to go over the score of 99.

I modeled it for them with me being one player and the rest of them playing against me.
For that game we got to see all of the cards, 
but when they played with their partners, 
they kept their cards hidden.
They LOVED it! 
(Warning - it did get kind of loud!)

Here is what they revealed about their strategies...

Whew!  That's a whole lotta learnin'!

What have you been up to?


  1. I love it! I am headed over to amazon to buy the book now. I think this will be perfect for my small math group during Daily math! Thank you for giving such a clear and wonderful description. I am always so nervous to buy books without knowing what I am getting.


  2. Wow Teresa,
    Your class has been busy. Thanks for sharing the games AND the kiddos' writing. There is obviously some great thinking happening during these games. The book will have to go on my wishlist I think! :)
    I love the anchor charts too!

  3. I love your ideas and I just had to go get my own copy of the book. Thanks for sharing!


  4. I love these ideas. I am ordering my book now. Thanks.

  5. I absolutely LOOOVEEE how much Math you're doing and how awesomely engaging all your students are! I'm currently doing probability with year 9 and am amazed how many students have no idea about a deck of cards! Loving them in your pics :) I'm your newest follower! :)

  6. There is certainly a lot to know about this topic.
    I love all of the points you've made.
