3 Homework Dear Family, (PAGE OF 2) Homework is an important link between learning in and out of school. Homework assignments provide reinforcement of the work students do in math class. Here are some suggestions for making the homework experience successful for your child. Set a regular time every day for homework, and establish a quiet place for your child to work (whether at home, in an after-school program, or at another location). Establish a system for bringing homework to and from school. Use an assignment book, a homework folder, or other organizational tools. Students will bring home the materials and directions needed to do homework activities. Certain materials will be used repeatedly throughout the year. Because these will be sent home only once, please help your child find a safe place to store these math materials perhaps in a math folder or envelope so that they can be easily located and used when needed. If your child regularly does homework in more than one place, we can discuss how to obtain the necessary materials. In our math class, students spend time working on problems in depth and are asked to share their reasoning and solutions. It is most important that children accurately and efficiently solve math problems by using problem-solving methods that are meaningful to them. At home, encourage your child to explain his or her strategies and mathematical ideas to you. UNIT 5 SESSION.3
4 Homework When your child asks you for help in solving a problem, it may be helpful for you to ask questions, such as these: (PAGE 2 OF 2) What do you need to figure out in this problem? Does this remind you of other problems? What part of the problem do you already know how to solve? What is a good place to start? What have you figured out so far? Would drawing a picture or diagram help? How can I help you (without telling you an answer)? If you would like to share any thoughts with me about how your child is approaching a homework task, please feel free to send me a note. If an assignment seems too difficult, too confusing, or perhaps too easy, please let me know so that I can address the issue. I look forward to working together throughout the year. UNIT 6 SESSION.3
5 Practicing Multiplication Facts Dear Family, (PAGE OF 2) To develop strong computation strategies for multiplication with multidigit numbers, students need to be fluent with the multiplication facts up to 0 0, often known as multiplication tables. Students were expected to learn these multiplication facts in Grade 3, and they reviewed and used them in Grade 4. The beginning of the school year is a good time for Grade 5 students to review these facts and identify any facts they may still not know fluently. The sheer number of multiplication facts to remember can seem overwhelming, and many adults recall the task of memorizing the facts. In school, students have learned these facts in categories of related facts to help them. As Grade 5 students review the multiplication facts, they identify the facts they still need to practice. They record the facts they are still learning, and they add clues to help them with those facts. Students use a fact that they know, which is close to the fact they are solving, and then they adjust to find the product. Here are some examples: 9 8 = = 72 Clue: 0 8 = = = 42 and 7 6 = 42 Clue: 6 5 = = = = 32 and 8 4 = 32 Clue: 2 8 = = 32 UNIT 7 SESSION.3
6 Practicing Multiplication Facts As they practice using the clues, students gradually come to know the facts that are difficult for them. Here are some suggestions to help your child learn the multiplication facts. (PAGE 2 OF 2) Ask your child which multiplication facts he or she is practicing. Find out what clues your child has chosen to help learn these facts. Choose two or three of the facts at a time to review together. UNIT 8 SESSION.3

You can use them at home to enrich your child s mathematical learning experiences. Estimating Any time you need to estimate amounts at home, try to involve your child. Look for ways to count or estimate large numbers of things, like floor tiles or windowpanes, or the number of cookies you ll need to make for a big party. Encourage your child to think of different ways to figure out about how many. Everyday Computation Notice when you use multiplication and division in your everyday life. Enlist your child s help. For example, if you are planning a picnic, have your child help figure out what you need to buy. If there are 20 slices in a loaf of bread, how many loaves will you need if each person eats two sandwiches? How Did You Solve That? Ask your child to tell you about how he or she is multiplying and dividing. Show that you are interested in these approaches. Because these strategies may be unfamiliar to you, listen carefully to your child s explanation; you might even try to do a problem or two, using the new procedure. Let your child be the teacher!

You can use the activities to enrich your child s mathematical learning experience. Playing I Spy Polygons and Angles To help your child continue to investigate the properties of polygons (especially triangles and quadrilaterals) and patterns involving their sides and angles, find figures around the house that fit a rule and play a guessing game. For example, you might describe a mirror by saying, I m thinking of something in this room that has two equal sides, at least two equal angles, and at least two parallel sides. What could it be? Then have your child identify objects that fit that rule, while trying to guess which specific object you were describing. Practicing Perimeter Estimating or calculating the perimeter of objects around the house is a good way to help your child use this concept in a variety of situations. There are many examples: the perimeter of a rectangular table, the perimeter of a room or rug, the perimeter of the refrigerator door or sink. You can measure perimeter in standard units of measure (such as inches or centimeters) or in nonstandard units (such as hand widths). Work with your child on estimating perimeters by measuring the perimeter of one object (for example, the sink), and then using this information to estimate the perimeter of a nearby object (for example, the refrigerator door).
