Activities:

• Have bags of five $1 bills, 15 dimes and 4 sticky notes ready for each pair of students.  "With the money in your bag, create each amount as I say it.  You will make 4 groups $1.30; $2.10; $0.70, $2.40. Now write the amount of money each group contains on a sticky note to match to the group."  Have studetns share their responses with the class.
• "Cover All" game-from Mrs. Reynolds.  Students draw a card with an amount printed on it.  They then color in a 100 grid to show the amount.  The students take turns drawing cards and filling in their grids.  The first one to "Cover All" of the grid is the winner.

• Decimals and Money: one dollar = 1 whole; 10 dimes in a dollar = .1 of a dollar; 100 pennnies in a dollar, 1 penny =.01.  Continue with decimals amounts greater than 1. $6.52 = 6 dollars + 5 dimes + 2 pennies = 6 ones + 5 tenths + 2 hundredths
• READ: six dollars and fifty-two cents
• DECIMAL: six and fifty-two hundredths
• REAL LIFE CONNECTIONS:
• Teacher read an article in which a patient died because the Dr./Nurse gave him the wrong dossage (incorrect decimal).
• Get packaging from McDonals (big mac, chicken nuggets, etc.)and make a poster board with prices.  Then have students buy items, add decimal, and calculate their change or how much more money they need.
• Menus from different restaurants (Los Cucos, Chillis, Olive Garden, Red Lobster, etc.). Have students play waitress and customer.  Students order from the menu and the waitress adds the prices. 
• Teacher can also have a list of questions for each menu.
• How much is it for _____  and ____ ?
• What is your change if you order _____ and _____ and you pay with a $20.00?
• Students build decimal numbers and shade corresponding pictures for decimals less than, equal to, and greater than one. 
• Students build equivalents decimals to make the connection

• Students use grids to compare and order decimals

• Have students compare and order more than two decimals

• Next TEK: 4.2D relate decimals to fractions that name tenths and hundredths using concrete objects and pictorial models

• Clothes Line -- teacher sets-up a clothes line for students to order decimal numbers, written on cards, in order from least to greatest.  The answer is in the front of the room on paper for students to check their work when they are finished.
• Decimal War -- comparing and ordering decimals (Mrs. Reynolds)
• Decimal Ring -- Adding and subtracting decimals (Mrs. Reynold)
• Cover ALL -- pick a card and cover board with ones and tens manipulatives.  The student that covers the board first wins.  Students need to use their strategies to decide if they need to place a cube or a rod.
• Decimal Dialogue -- from Motivation Math by Michael L. Lujan pg 18.  Students roll 2 dice and find the cordinates (intersection of the row and column) on the game mat.  Then the student reads  aloud the decimal number written in the square.  For example: 3.8 = three and eight tenths.
