Have them experiment and collect data and record.
ComputationEstimate how much water you could conserve by turning off the tap while you brush your teeth. How could we figure out the answer to this problem more precisely?
Questions students if the calculations are correct. A leak that fills up a coffee cup in ten minutes will waste over 3,000 gallons of water in a year - pg. 42. ( 8 oz. /(cup) x 6 c./ hr x 24 hrs/day x 365 days/yr. = 420,480 oz/yr. Dividing by 128 oz in a gallon indeed equals 3,285 gal. a yr.

Able to think of and use another number pattern to create a storyDiscuss the factorial numbers- To get to the total the calculation would be to multiply the first ten counting numbers together. They are represented by dots in the back of the book in arrays. 1 x 1 =1, 1 x 2 = 2, 1 x 2 x 3 =6, 1 x 2 x 3 x 4 = 24, 1 x 2 x 3 x 4 x 5 = 120. It helps the learner to visualize the abstract numerical pattern of factorials by illustrating numerical progressions through pictures, narrative, arrays and numbers.The Big Friendly Giant is seen by a little girl named Sophie. He snatches her from her bed and arrives in his home, a secret cave underneath a big stone. Sophie learns that he is friendly. She does meet the mean giants, however. They eat humans every night. Sophie does not like this and she and the BFG set out to get rid of the bad giants. The Queen of England helps out and they capture the bad giants. Bunches and Bunches of Bunnies - Louise Mathews
Measurement - Proportion, Scale
Proportion - The BFG is 6 times as large as Sophie. If he is 24 feet tall, how tall is Sophie? The other giants were at least twice as big as the BFG. One of the giants was 54 feet tall. Use that to make up problems.
Chapter - "The Royal Breakfast" - Everyone was busy creating furniture that would fit the BFG. See how they determined the measurements. They used a base of a 6-foot tall man. What didn't they use Sophie's height? Use pg. 56, "So Big"
Use grid and scale to draw a larger picture from a small one. See pg. 57.
Feet size - What foot size would the BFG be if he is 6 times as tall as Sophie? Brainstorm the process of figuring it out. (Since the BFG is 6 times as large as Sophie, his feet would be also.) Find a student who is Sophie's height, 4 feet tall. Trace the foot pattern. Cut out the pattern, and arrange them in the shape of a foot so they are six wide and six long. Glue the feet together and draw the outline of a large foot around them. Cut out the "big foot" and mount it on the wall.
Extension: From inch tall to giant. Use Jim and the Beanstalk, Raymond Briggs. The giant can't see and needs glasses. Used a gold coin to measure for the lens. He also needed his teeth redone. Then, he needed a wig. Needed red hair and curly.

Talk with your group.

He finds it at home on the floor. Feeling bad, he decides to sew all the buttons that his friends find on his jacket. He gives the jacket as a gift to his good friend, Frog. Gator Pie - Louise Mathews
Number Sense - Attributes
Sorting buttons - Use a felt board to allow students to manipulate the story. In groups, have children select a handful of buttons and sort them according to a specific attribute. They need to describe their attribute.
"Button Factory" - Tell the class you are a shirt designer and need buttons for your shirt. Hide a button in your hand and describe its attributes. Have children draw the button. Have the children continue the game in pairs.
One difference Train - Prepare one set of buttons for each pair of children. Use Activity sheet 20 on two colors of construction paper. One child is each group places a button on the construction paper. Another child finds a button that is different in only one way, then places it next to the first button. Partners continue, in turn, to form a one-difference train.
"Button Up" - Describe an attribute of a button such as color, size, shape, number of holes, … If the children are holding a button with that attribute they hold the button up.
Estimate the buttons in a jar - Ask the children to guess the amount of buttons that would fit in a jar. Do not show the children the jar or the collection. Indicate to the children that it is difficult to get an accurate prediction because they do not have enough information. Suggest that if they saw the jar they could get closer to the number of buttons. Have them verbalize their estimation. Ask them how they arrived at that estimation.

They were twisting and turning and pointing their beaks toward the sun as they took their readings and plotted their courses south. With a start, Miyax noticed the sun. It was halfway below the horizon. Shading her eyes, she watched it disappear completely. The sky turned navy blue, the clouds turned bright yellow, and twilight was upon the land. The sun had set. In a few weeks the land would be white with snow and in three months the long Arctic night that lasted for sixty-six days would darken the top of the world. About an hour later, the sun arose and marked the date for Miyax. It was August twenty-fourth, the day the North Star reached Barrow. Of this she was sure, for on that day the sun lingered below the horizon for about one hour. After that, the nights lengthened rapidly until November twenty-first, when the sun disappeared for the winter."
Miyax knows what season it is and the exact date. How does she know these things? How will Miyax know when it is November 21? What will the next 3 months be like?

"One Inch Tall"- Shel Silverstein (Read the poem)
If you were only one inch tall, you'd ride a worm to school.
The teardrop of a crying ant would be your swimming pool.
A crumb of cake would be a feast.
A flea would be a frightening beast
If you were one inch tall.
If you were only one inch tall, you'd walk beneath the door.
And it would take about a month to get down to the store.
A bit of fluff would be your bed.
You'd swing upon a spider's thread,
And wear a thimble on your head
If you were one inch tall.
You'd surf across the kitchen sink upon a stick of gum.
You couldn't hug your mama, you'd just have to hug her thumb.
You'd run from people's feet in fright,
To move a pen would take all night,

How can this be?
How does this compare to Gulliver's Travels?
Have students create comparisons of different objects from different perspectives.
We develop number sense by comparison. Have students create statements using this form: ____ could not be the number of _____, but it could be the number of ____. Have them do this for small numbers, medium numbers, and large numbers. Do not specify which are small, medium, and large. You will be able to assess their number sense by their choices. Students can work in pairs and illustrate their statements on newsprint. These make colorful, interesting, and sometimes amusing wall displays.
Examples:100 could not be the number of kids in this class, but it could be the number of keys on a piano. 5000 could not be the number of houses on a block, but it could be the number of shreds of cabbage in coleslaw. 1,000,000,000 could not be the number of books in our library, but it could be the number of people in China. Humbug wants to travel by miles because it's shorter, and Milo wants to travel by half inches because it's quicker.

Pg. 179-180 - " By the eight million two hundred and forty-seven thousand three hundred and twelve threads in my robe, I'll say there are."
Is this reasonable? How is this number written with numerals? What word is inserted incorrectly?In chapter 16, Milo meets half a child. Milo is a little surprised by this child because he has never seen half a child before. The child responds, "It's .58 to be precise". He responds from the left side of his mouth (which happened to be the only side of his mouth). The conversation continues, "I beg your pardon? " said Milo. "It's .58," he repeated; "it's a little bit more than a half." (see book, pg. 196)
Number Sense - Infinity(see pg. 189-191) The mathemagician tells him "add one to it. Now add one again. Now add one again. Now add one…" - the largest number.
