Multiplication 1 Unit 3Module 5Cluster 1 Odd and Even NumbersActivity Sheets 108–117Cluster 1 IntroductionThe instruction begins with identifying multiples of 2 using pictures of familiar objects. Multiples of 2are identified as pairs, even numbers, and equal addends. A review of skip counting provides a softintroduction to multiplication.The activities focus on even numbers within 10, using pictures and numerals together beforeproceeding to numerals by themselves. Students match sets of objects to even numbers. Afterreviewing even numbers, they practice the process with odd numbers—pairs plus one. The activitiesmirror those used for even numbers to ensure familiarity.The cluster develops the generalization for even numbers: even numbers are made of two equaladdends. It reinforces the addition strategy of doubles and emphasizes the language of partners aspairs. Identifying pictures of sets of objects as odd or even and matching pairs of equal addendsconcludes the basic introduction to odd and even numbers within 15.Distribute activity sheet 108 to the students.Instructional InsightInstruction: activity sheet 1081Deepening current understandingof familiar concepts and languageis foundational to building anew concept.1You may already know about odd and even numbers.You will use that knowledge to use pairs in multiplication.Multiplication is another operation used with numbers.Multiplication is repeated addition. You will learn more aboutmultiplication in the next few weeks.Name1The two skills you will apply to multiplication are pairs andodd and even numbers. Discuss with your partner things thatcome in pairs. Did you talk about eyes, ears, hands, legs, feet,glasses, earmuffs, gloves, jeans, shoes, and boots?What are some other things that come in pairs?If you were to define a pair to someone who knewnothing about pairs, what would you tell dBeven8AoddBeven9AoddBeven10AoddBeven5In pairs, there are two things that are the same. When wethink about a pair of eyes, it is two eyes. It is not one eye andone ear.We talk about pairs of glasses and pairs of jeans. Do thosephrases mean two sets of glasses and two sets of jeans? Thinkabout it.SGU3M5evenB42 2017Bodd3List the key ideas on the whiteboard as they are shared. Since pairs are two things that are the same, all pairs are evennumbers. Think about that.oddA2There are some key things to remember about pairs. I willwrite them on the whiteboard as we discuss them.No. A pair of glasses includes two lenses. It would be hard towear a glass. A pair of jeans includes two pant legs. It wouldbe funny to wear a jean. On the back of your activity sheet,draw a picture of someone wearing a glass or a jean. Sinceeyes and legs come in pairs, the coverings for them must alsocome in pairs.AList the even numbers.2 , 4 , 6 , 8 , 10List the odd numbers.1 , 3 , 5 , 7 , 9 2017SGU3M5Even Numbers108108Basic BackgroundIdentifying attributes of pairs isprobably new for many students.Take time to structure theirthinking, which will preparestudents for multiplication.2125

Second GradeUnit 3Module 5Cluster 1 Odd and Even NumbersActivity Sheets 108–117Draw a number line 0 to 10 on the whiteboard . Draw tick marks for the even numbers .Start at 0, and skip count by 2 . I will write the numbers as yousay them: 0, 2, 4, 6, 8, 10 .1Basic BackgroundNumber lines are good modelssince skip counting can bequickly recognized .1These numbers are pairs . Think of them as doubles . Whattwo equal addends make 2? Yes, 1 1 . What two equaladdends make 4? Yes, 2 2 . How about 6? 8? 10? Wheneveryou have two equal addends, the result is an even number .The sums will always have 0, 2, 4, 6, or 8 in the ones place .Let’s talk some more about pairs . Do the two items in a pairhave to be exactly the same? No, they only need to be alike inone way .Demonstrate examples with a deck of playing cards . Here are two 5s, a pair of 5s . They both represent the number5 . Are they exactly the same? No . One is a club; the other isa diamond . When talking about the value of the card, the suitand the color don’t matter .Another key is that a pair is two items that are typically usedtogether, two partners . Think about a married couple, twins,dance partners (e .g ., pairs of ice skaters), tires on a bicycle,names of businesses (e .g ., Abercrombie and Fitch, Barnes andNoble, Sears and Roebuck), and many more . Can you think ofpairs or partners that you see every day?pair 2 ddBevenoddBevenPlease look at this activity sheet . Each row has a number ofsocks from 1 to 10. Does the one sock in the first row have apartner? No . Is it an even number? No . All items in an evennumber have partners . Fill in the bubble for A, odd .2Draw a ring around the two socks in the second row . Is thisa pair? Does every sock have a partner? Yes . Is 2 an evennumber? Yes . Fill in the bubble .6A7AoddBeven8AoddBevenDraw a ring around each pair of socks in the third row . Howmany socks are in this row? Does every sock have a partner?No . Is 3 an even number? No . Fill in the bubble .9AoddBeven10AoddBeven345Draw a ring around each pair of socks in the next row . Howmany socks are in this row? Does every sock have a partner?Is 4 an even number? Fill in the bubble .List the even numbers.2 , 4 , 6 , 8 , 10List the odd numbers.1 , 3 , 5 , 7 , 9 2017SGU3M5Complete the other rows the same way . Draw rings aroundeach pair of socks . If every sock has a partner, the numberis even. Write the number if necessary, and fill in the bubble.Please put your pencil down when you have finished.Read the directions in the box at the bottom of the page . Ifyou do not know the numbers to write, what can you do? Yes,look at the numbers with the rows of socks . All the numbersmarked B are even numbers. They go on the first set of lines.All the numbers marked A are odd numbers . They go on thesecond set of lines. When you have finished, read each set.Independent PracticeNo independent practice is recommended .1126AEven Numbers12108108AoddBevenAoddBevenInstructional InsightExtending pairs to identify oddand even numbers is included inthe instruction and guided practice .This provides the frameworkfor multiplication .1 2017SGU3M5
