4th Grade Winter Recess Packet, December 2014 - January 2015
To our parents, and guardians:
This packet was designed to help your child prepare for the New York State Mathematics and NYC Science tests. Please guide your child by monitoring their daily progress and completion.
All work is due on Monday, January 5, when school resumes. Thank you for supporting your child's success.
Signature: I have read and will monitor my child's daily study schedule. __________________________ ________________________________________________________________________________________
Dear ________________________ , after completing your math lesson each day, record what you've learned.
Use this schedule to record one math fact, and one science fact that you've learned, every day. EXAMPLE: In math, I learned that the number 250 has 25 tens. 25 x 10 = 250 and 250 ÷ 10 = 25

My 4th Grade Science Vocabulary Notes
Life Science
Producers have the greatest amount of energy. They are green plants that make their own food.
Draw, color and label a producer:
Consumers eat the producers or eat other consumers. Example: A beetle eats a leaf then a bird eats the beetle; both are consumers.
Draw, color and label two di�erent kinds of consumers:
Decomposers feed on dead producers, consumers, and wastes. They help to also break it down into the soil. Examples of decomposersinclude worms, �ies, mushrooms (a fungus) and mold.
Draw, color and label three di�erent kinds of decomposers:
_________________________________________________________________________________________In�uence of Human Activity on Ecosystems
Humans can have a major impact on ecosystems. Impacts can be positive or negative:
Negative Impacts:- Pollution is when harmful substances are added to Earth’s water, air, or land.- Water pollution can be too dirty to use. It can make living things sick which could end up killing the plants and animals living in it.- Air pollution can come from forest �res, cars, or factories. They release acids that mix with water in the air and can fall as acid rain. Smog hangs in the air like a cloud and makes it hard to breathe.- Land pollution is caused by trash being thrown to the ground. This can harm plants and animals. It can make the land ugly.
Positive Impacts-Laws that control air and water pollution-Using resources wisely-Public parks and forests to control how land is used-Laws that protect endangered species Illustrate and title an example of pollution.

278 UNIT 4 LESSON 4 Find Just-Under Quotient Digits
� Choose Between Calculation and Mental Math
Some problems have numbers that are easy to work with mentally. Other problems are easier to solve using pencil and paper or a calculator.
Use Mental Math
Some problems may contain numbers that are easy to work with mentally.
Example: There are 150 ribbons to be handed out at the school Field Day. There are 30 events, and the same number of ribbons will be awarded at each event. How many ribbons will be given out at each event?
The numbers in this problem are multiples of 10. Think: 150 � 30 is the same as 15 � 3, so the anwer is 5. Also, 30 � 5 � 150.
Use Calculation
If the problem asks for an exact answer and there is no noticeable pattern, then you will have to do the calculation.
Example: Last month Mandy was in school for 132 hours. She spent 6 hours in school each day. How many days did she go to school?
We need to find 132 � 6. This is difficult to do mentally, so use paper and pencil or a calculator: 132 � 6 � 22.
Solve. Then write the method you used.

230 UNIT 4 LESSON 7 Multiply and Divide with 9
4–7 Name Date
� Math Tools: Quick 9s MultiplicationYou can use the Quick 9s method to help you multiplyby 9. Open your hands and turn them so they are facingyou. Imagine that your fingers are numbered like this.
To find a number times 9, bend down the finger forthat number. For example, to find 4 � 9, bend downyour fourth finger.
The fingers to the left of your bent finger are thetens. The fingers to the right are the ones. For thisproblem, there are 3 tens and 6 ones, so 4 � 9 � 36.
Why does this work? Because 4 � 9 � 4 � (10 � 1) � 40 � 4 � 36
You could show 3 tens quickly by raising the first 3fingers as shown above.

� Math Tools: Quick 9s DivisionYou can also use Quick 9s to help you divide by 9. For example, to find 72 � 9, show 72 on your fingers.
