Multiplication and Division with 0 - 5, 9, and 10: Pre-Assessment (SLO) 1 day; 19 lessons (Lessons 6, 9, 14, and 18 may take 2 days); Quick quizzes and Strategy/Fluency Checks -- 4 days; Unit Assessments 2 days; Total days -- 30.Meanings of Multiplication and Division: 5's and 2's1.1 Multiply with 5OA. 1, OA.4, OA.7, OA.9There are quite a few routines and materials that need to be managed in these first two units. Read about them in the Math Background pages. Consider how you want to manage the materials and where you would like to store the materials to complete the recommended dashes and signature sheets. There are several strategy cards to keep track. Additionally, students use the white boards and number paths to keep track of their count bys., read description on page 1W in the teacher text book. Please read the "Teaching Note" on page 3 about the convention of group size. count-by, equation, multiplication, factor, product, multiplier, multiplesI can dentify and use patterns to multiply with 5.Describe ways to find 8 x 5. Hector has some nickels in his pocket. He has no other coins. Could he have exactly 28¢? Explain.
1.2 Multiplication as Equal GroupsOA.1, OA.3, OA.7Have small paper plates and counters available for students who may need a more concrete experience creating equal groups before they are able t represent the equal groups drawings.equal groups, in each, in every, per, equal shares drawing, function tableI can use multiplication and drawings to represent equal groups situations.Draw an equal shares drawing to find the number of markers in 8 packages of markers with 5 markers in each package; you know that 2 x 4 = 8 and that 40 is the same as 4 tens. Explain how you could use this infomration to find 2 x 40.
1.3 Multiplication and ArraysOA.1, OA.3, OA.5, OA.7Important: Quick Practice for fluency. Fluency folder made from pages 15-18 student activity book. Linking cubes can be used as a concrete representation of arrays.array, row, column, Commutative Property of MultiplicationI can use arrays and the Commutative Property in multiplication.Draw arrays to show why 2 x 5 equals 5 x 2. How can you use 7 x 9 = 63 to find the unknown factor in the equation 9 x __ = 63?
1.4 The Meaning of DivisionOA.1, OA.3, OA.4, OA.5, OA.7Activity 2 is a STRONG concept builder. Students are asked to relate multliplication to division and determine the meaning of the factors and the product to see how they relate to the divisor, dividend, and quotient. Be sure to give students ample opportunities to discuss and make meaning of the numbers in the situations. division, dividend, divisor, quotientI can relate division to multiplication with an unknown factor.What multiplication equation with an unknown number can you write to find 20 ÷ 5 = ___? Explain how you can use a multiplication equation to find the quotient 40 ÷ 5.
1.5 Multiply and Divide with 2OA.1, OA.2, OA.3, OA.4, OA.6, OA.7, OA.9The number line can be a helpful tool to keep track of student count bys. If students are having a hard time keeping track of the count bys and the total number of items, have them count stacks of linking cubes so they can clearly see the number of groups. The Check Sheets are a way for students to record their practice. The Check Sheet Answer strips are found on page M7 of the Teacher Resource Book (TRB)multiplier, pictograph, even number, odd numberI can identify patterns in 2s count-bys and multiplications and relate multiplication and division.Explain how patterns in the 2s count-bys and mutiplications can help you when multiplying; How is finding the number of earrings in 6 pairs diffrent from finding how many pairs you can make with 6 earrings?
