Multiplication Project Your child has been assigned a multiplication project. This project is worth one math test grade and is done at home. Your child is to model and display multiplication using 5 of the following strategies: arrays, repeated addition, rectangular array, skip counting, a number line, the commutative property, and equal groups. This must be done on a poster board, poster paper or students may create a book with each strategy on a different page. Each model must include the multiplication sentence with it. The students can model each of these strategies by drawing pictures, using household materials like cotton balls, dried foods (pasta, beans, etc), stickers or craft supplies, or cutting pictures out of newspapers or magazines. Students will select one multiplication sentence (please refrain from using the 0 and 1’s multiplication facts) and represent that ONE multiplication sentence using each of the strategies. Note that the same multiplication sentence will be used throughout the project, but it will be represented different ways (ex: if a student chooses the fact 4 x 3 = 12, that multiplication sentence will be used for the entire project, yet it will be represented using each strategy). Each student will be judged on neatness, accuracy of each model, creativity, and completion. All projects are due on or before Friday, January 8th, 2016. Projects may be turned in early but NO LATE PROJECTS will be accepted. Please refer to the 3rd grade website keyinto3rd.weebly.com as well as the rubric on the back of this sheet to obtain the most points possible. –Ms. Callaway Optional extra credit – DIVISION PROJECT For up to 35 points extra credit you may also create a division poster board. Again, choose one division equation to model or display. The division one must have FOUR models. Also due no later than Friday, January 8th, 2016 Division strategies: repeated subtraction, number line, skip counting, equal groups, or an array. Choose ONE division equation to solve and model solving that equation in 4 different ways. Be sure to label the equation next to each model. This must be done on a poster board, poster paper or students may create a book with each strategy on a different page. The students can model each of these strategies by drawing pictures, using household materials like cotton balls, dried foods (pasta, beans, etc), stickers or craft supplies, or cutting pictures out of newspapers or magazines. Students will select one division sentence (please refrain from using the 0 and 1’s facts) and represent that ONE division sentence using each of the strategies. The division projects will be scored will also be judged for neatness, accuracy, creativity, and completion. See example drawn below. Categories 0-1 points 2-3 points 4-5 points The array does not represent the multiplication sentence. The array did not represent the multiplication sentence being used, but it did represent multiplication. The array accurately represented the multiplication sentence being used. The addition used is not adding the same amount each time. It does not represent any multiplication sentence. The addition is repeating, but it does not match the multiplication sentence being modeled. The addition is repeating and matches the multiplication sentence being modeled. The rectangular array does not represent the multiplication sentence. The rectangular array did not represent the multiplication sentence being used, but it did represent multiplication. The rectangular array accurately represents the multiplication sentence being modeled. The skip counting does not use equal intervals between numbers. It does not represent the multiplication sentence. The skip counting does show equal intervals between numbers, but it does not match the multiplication sentence being modeled. The skip counting does show equal intervals and represents the multiplication sentence being modeled. The number line does not use equal moves. It does not represent any multiplication sentence. The number line does use equal moves, but it does not match the multiplication sentence being modeled. The number line does use equal moves and represents the multiplication sentence being modeled. Array 2 x 5 = 10 XXXXX XXXXX Repeated Addition 7 + 7 + 7 = 21 7 x 3 = 21 Rectangular Array 4 x 9 = 36 Skip Counting 8 x 7 = 56 8, 16, 24, 32, 40, 48, 56 Number Line 0 1 2 3 4 5 6 7 8 9 10 2 x 5 = 10 Equal-Sized Groups 3 x 4 = 12 Commutative Property The groups do not contain the same amount. It does not represent any multiplication sentence. The groups contain the same amount, but they do not match the multiplication sentence being modeled. The groups contain the same amount and represent the multiplication sentence being modeled. There are two equations but they do not represent the commutative property. There are two equations that represent the commutative property, but they do not represent the property for the sentence modeled. There are two equations that accurately use the commutative property for the multiplication sentence being modeled. Student did not do any of the work, or did not complete the work. Student did not do most of the work. Student project was on time and student completed most/all of the work. If 3x4 = 12 then 4x3 = 12 Student self-evaluation Students will self-grade their level of completion and amount of work put into their project. Creativity & Neatness Models must be neat, well organized and arranged. All words must be spelled correctly and written neatly. The models were arranged in a sloppy order. The information was not clear and did not display any creativity. (Reminder: Students must only show 5 of the 7 ways listed). The models were arranged somewhat neatly. The writing was legible, but the information was not colorful or eye- catching. All models did not include a multiplication sentence. The models and handwriting were neat. Student used an original design to display information in a colorful, eye-catching way. All models included a multiplication sentence. ______ / 35
