Preschoolers are a joy. Their imaginations never stop. They’re interested in everything, and they want to go, go, go! They burst with pride over their newly-developed abilities—to hop on one foot, to write their names in crooked print, or to know where to put the forks on the table. Most preschoolers are just as curious about numbers as they are about outer space or ladybugs, but preschool math is often a dreary and boring affair. Workbooks abound for learning to count and write numbers, but preschoolers need to move, talk, and play as they begin to explore the world of math. That’s where this book comes in. You won’t find a single worksheet in it. Instead, you’ll find simple (but effective) games and activities to enjoy with your preschooler. Your child will master the numbers from zero to ten as the two of you count blocks, hide stuffed animals, jump from number to number, and play games. As the two of you enjoy these activities together, your child will learn far more than just counting to ten, though. Rather, your child will also learn to visualize the numbers up to ten and to match quantities with written numbers. She’ll learn to compare numbers, and she’ll even lay a foundation for addition and subtraction as she takes numbers apart and explores combinations. With a deep understanding of the numbers up to ten, your child will be well-prepared for kindergarten. Perhaps even more importantly, she’ll start her formal schooling with a positive attitude toward math! Introduction Page 2 What Your Child Will Learn All of the activities in this book focus on the four key skills that help preschoolers develop a thorough understanding of numbers: counting, subitizing, comparing numbers, and recognizing written numerals. Counting: more complicated than adults realize Counting seems very basic, but it is actually very complex. To be able to count accurately, a child has to learn: • The order of the counting words (“one, two, three,” etc.), • That any kind of thing can be counted (blocks, sounds, jumps, people, etc.), • That you have to count each item once and only once, • That you can count objects in any order, • That the last number said when counting is the total number. (For example, young children can often point to blocks and say “one, two, three” but aren’t able to say how many blocks there.) You don’t need to discuss these concepts explicitly with your child, though. Children learn them naturally through repeated exposure to counting, and they’re all embedded in the activities in this book. Introduction Page 3 Subitizing: recognizing quantities without counting While learning counting strategies is essential, children also need to learn to recognize groups of items without counting. This skill is called subitizing. Recognizing small quantities helps children start to think of numbers as groups and understand the relationships between numbers. In this book, you’ll use a five-frame for some of the beginning activities. Take a look at the five-frame below. Notice how you can immediately “see” that there are three circles, and that two spots are empty? When you do this, you’re subitizing. Organizing blocks on the five-frame helps develop this crucial skill and helps children move beyond one-by-0ne counting to solve problems. Once your child is familiar with the five-frame, you’ll then use a ten-frame. The ten-frame is especially useful for noticing relationships between numbers. For example, can you tell how many blocks are on this ten-frame without counting? You might have noticed that there is one empty box and figured that there must be nine blocks. Or, you might have noticed that there are five blocks on the left-hand side and four blocks on the right-hand side, for a total of nine blocks. Either way, you were using relationships about numbers to find the total, rather than one-by-one counting, and that’s the kind of thinking you’ll help your child develop with the activities in this book. While this book will leave the + and – symbols for kindergarten, learning how to subitize will provide a huge advantage to your child when she first encounters written addition and subtraction problems. Introduction Page 4 Comparing numbers: more, less, or equal? As children start to visualize quantities and understand numbers more deeply, they learn that the numbers that come later in the counting sequence signify greater amounts than the numbers that come earlier. (I.e., since six comes after five in the counting sequence, six is more than five.) Before children are able to reach this level of abstraction, however, they need plenty of experience with concrete materials. Once they’ve spent some time comparing numbers of objects, they’re then ready to begin comparing spoken numbers without counting out the corresponding number of objects. Recognizing written numerals: making the connection between quantities and symbols Recognizing the written numbers is essentially reading— matching a printed symbol to a spoken word. Before children are ready to deal with the abstract written symbols for numbers (1,2, 3, etc.), they need plenty of experience with quantities and the number words. In this book, written symbols are addressed in the final chapter, with lots of time spent making the connections between the written symbols and what children already know about numbers. Introduction Page 5 How to Use This Book Start when your child is interested Most children will be ready to start the activities in this book around age four. If your child becomes interested in numbers at age three, go ahead and start trying some of the activities. No matter what age your child is, if there’s frustration or tears, stop! Put the book away for a month and then give it another try. Sometimes, children’s brains just need a little more time to mature before they’re ready to understand number concepts. Follow your child’s lead for pacing the activities If your child has a lot of experience with counting, he may breeze through the first chapter of counting activities. Or, if your child is younger, you might spend a lot of time on chapter one. Take as much time as you need with each section, and feel free to skip concepts that your child has already mastered. In general, the activities grow in complexity from the beginning of each chapter to the end, so move on from activity to activity as your child is ready for more challenge. Introduction Page 6 Have a consistent (and short) math time You’re more likely to remember to do math if you choose a consistent time each day. You might do a little math together before bedtime, or you might play with numbers after morning snack each day. Most four-year-olds have a very short attention span, so don’t expect a twenty-minute, focused lesson. You’ll be amazed at what your child will learn after a year if you do math for just five minutes per day several times per week! Make a math basket It’s much easier to do math together consistently if you don’t have to hunt around your house for supplies. To make it as easy as possible to have math time each day, put together a small “Math Basket” with your supplies. You will need: • This book • 20 small blocks or counters (interlocking blocks, small wooden blocks, or poker chips are a great size, but you can use whatever you have around the house.) • Printables from appendix, preferably printed on cardstock (pages 37-43) • Two small brown paper bags (or some other small bags that you can’t see through) • Regular, six-sided die • Coin with heads and tails You will also occasionally need small toys (like stuffed animals or toy cars), a blanket, blank paper, and a marker, but you don’t need to keep these in your Math Basket. Introduction Page 7 “How many?” As your child masters counting, she needs to learn that the last number she says when counting is the total number. For example, she may be able to point to blocks and count “one, two, three,” but she may not be able to answer afterward when you ask how many blocks there are. Until she masters this important skill, make sure to ask her how many objects there are every time she counts. And, make sure you explicitly say how many objects there are every time you model counting. Weave math throughout the day Math is more than just numbers, but the other math concepts your preschooler needs to know will come up naturally during the day. Keep an eye out for opportunities to talk about patterns, clocks, shapes, and measurements, and use these teachable moments to introduce these ideas to your preschooler. This can be as simple as checking the time on the clock or measuring flour for pancakes together. Have fun! Math time for preschoolers should be fun! Feel free to adapt the games and activities to your preschooler’s personality. Use his favorite trucks for the counting activities, or pretend that the blocks on the ten-frame are people sitting on a bus. Preschoolers especially love peek-a-boo games and being in charge. In this book, you’ll see lots of hiding games and chances for your child to “be the teacher.” Go ahead and make the hiding games as dramatic and fun as possible, and enjoy the chance for your child to show off what she knows when she leads activities. Most of all, enjoy this one-on-one time with your preschooler. Introduction Page 8 Chapter 1 Recognizing Amounts and Counting to Five Goals • Count to five. • Recognize groups with up to five items by sight. • Introduce the idea of zero. Sample Activity 1.5 Feed the Stuffed Animal MATERIALS 5 small blocks or counters; stuffed animal; blank piece of paper or plastic plate ACTIVITY Set the blank paper or plate in front of the stuffed animal. Tell your child that the animal is hungry for two “cookies” (or apples) and ask her to put two of the blocks on the plate for the animal to eat. For added fun, use the stuffed animal as a puppet and have the animal “eat” the plateful. Repeat for other numbers of cookies up to five, including zero. Then, let your child choose the number of cookies and be the puppet-master. Chapter 1: Recognizing Amounts and Counting to Five Page 10 Chapter 2 Combinations That Make Five Goal • Become familiar with the combinations that make five (0 and 5, 4 and 1, 2 and 3). Sample Activity 2.2 Fingers Up, Fingers Down No special materials needed ACTIVITY Show your child four fingers, with your palm facing you. Ask how many fingers are up (four). Then, ask how many fingers are down without turning your hand around. After your child responds (one), turn your hand so that your palm faces your child so that he can confirm his answer. Repeat with other numbers of fingers. Then, let your child be the teacher and show different numbers of fingers to you. NOTE It might take your child a minute to figure out how many fingers are down. Make sure to give him some thinking time before offering any help. Children sometimes copy their parent’s hand with their own hand to see how many are down, and sometimes they look closely at the edge of the parent’s hand to see where the tucked fingers’ edges are. Whatever method makes sense to your child is fine; what’s most important is that she realizes that she’s capable of figuring things out. If she makes a mistake, just turn your hand around to show her how many fingers are down and then try again. Chapter 2: Combinations That Make Five Page 12 Chapter 3 Counting to Ten and Comparing Amounts Goals • Count to ten. • Understand what more, less, and equal mean. • Compare sets of objects up to ten. Sample Activity 3.4 Who Has More? MATERIALS 2 small paper bags with 10 small blocks or counters in each bag ACTIVITY Take a handful of blocks out of one bag. With your child, count how many you took. Leave these blocks out. Ask your child to take a handful of blocks out of the other bag and count the number of blocks. Talk about whether you have more, less, or an equal number of objects. Line the objects up next to each other to compare if your child isn’t sure. NOTE This activity is easier if each bag has different objects (for example, blue blocks in one bag and red blocks in the other.) Chapter 4: Connecting to Written Numerals Page 14 Chapter 4 Connecting to Written Numerals Chapter 4: Connecting to Written Numerals Page 15 Goals • Understand written numerals up to ten. Sample Activity 4.3 Number Jump MATERIALS 11 sheets of blank paper; marker; tape ACTIVITY With your child, count from 0 to 10. As you say each number, write it on one of the sheets of paper. Make the numbers large and easy to see. Have your child help you put the numbers in order on the floor from 0 to 10. (You may need to use a little tape to keep them from sliding.) Then, have your child start at 0 and jump on the papers in order up to 10, shouting out each number as she jumps onto it. NOTE Save these papers for the next activity. Chapter 4: Connecting to Written Numerals Page 16 Chapter 5 Combinations That Make Ten Goal • Become familiar with the combinations that make ten (0 and 10, 9 and 1, 8 and2, 7 and 3, 6 and 4, 5 and 5). Sample Activity 5.5 Make Tens Memory Game MATERIALS 2 sets of number cards 1-10 (pages 41-43) OBJECT OF THE GAME Win the most pairs of matching cards. ACTIVITY Shuffle both sets of number cards together and lay them out in a grid pattern, as in the game Memory. On your turn, flip over two cards. If the two cards make ten (for example, 6 and 4, or 7 and 3), you keep the pair. If not, turn them back over. Continue until all the cards have been matched. Whoever finds the most pairs wins. NOTE After your child turns over the first card, encourage him to say what card he is looking for before flipping the second card. Keep a ten-frame and blocks nearby so that your child can use the blocks to check any combinations he is unsure of.
