Module 3 Mathematical Concept Online Help Common Core Standards Word Problems using a Bar Model (aka Tape Diagram) and the RDWW strategy we use in class: R ead the word problem & extract (underline) the information needed to solve the problem Draw picture to represent the problem Write a number sentence horizontally to represent your drawing Write an explanation of your answer to check for reasonableness Word Problems using a Bar Diagram & RDWW This strategy is used throughout the Common Core curriculum to solve word problems Lessons 1-3: Area and Perimeter formulas Finding the perimeter Determining the missing side in perimeter Finding the area Determining the missing side in area 4.MD.3 Lessons 4&5: Use a place value chart to multiply by 10, 100, and 1,000 Using place value to multiply by 10, 100, 1,000 4.NBT.5 Lesson 6: Using the area models and array models to multiply Multiplication with the area and array models Multiplication with the area model Multiplication with number bonds 4.OA.4 4.NBT.5 Lesson 7: Multiply two digit number by one digit number Multiplying with a place value chart 4.OA.3 4.NBT.5 Lesson 8: Apply place value chart model to multiplying larger numbers & using partial products method to multiply Multiplying with a place value chart Multiplying with partial products 4.NBT.5 Lessons 9 & 10: Apply partial products method to multiply a standard multiplication algorithm Multiplying with partial products Multiplication algorithm Multiplication word problems 4.OA.3 4.NBT.5 Lesson 11: Use the area model and partial products to complete a standard multiplication algorithm Use the area model to multiply large numbers 4.NBT.5 Lesson 12: Use a tape diagram to solve multi-step multiplication word problems Multi-step multiplication word problems 4.OA.3 Lesson 13: Solve multi-step word problems that have multiple operations Multi-step word problems with multiple operations 4.OA.3 Lessons 14 & 15:Solve division problems with different models Division with an array model Understanding the bar model in division Understanding what to do with the remainder in a word problem Interpret a remainder 4.NBT.6 Lessons 16-19 :Solve division algorithms with place value Division with place value (concept is well represented, where she "cashes in" we unbundle) to understand the division algorithm 4.NBT.6 Lesson 20-21: Use the area model to solve division problems Area model used to solve division word problems 4.NBT.6 Lesson 22: Use factor pairs to understand prime and composite numbers Use factors to identify prime and composite numbers 4.OA.4 Lesson 23: Use division or the Associative Property to test for factors Use division to find factors of a number The Associative Property of Multiplication 4.OA.4 Lesson 24: Determine whether a whole number is a multiple of another whole number with the use of division Use divisibility rules to determine whether a number is a multiple of 2, 3, or 6 Use divisibility rules to determine whether a number is a multiple of 4 or 7 4.OA.4 Lesson 25: Identify prime and composite numbers Prime and composite numbers 4.OA.4 Lessons 26-32: Use place value to divide large dividends by a single divisor Division with place value (concept is well represented, where she "cashes in" we unbundle) to understand the division algorithm Divide three digit dividends using "friendly multiples" Divide four digit dividends using "friendly multiples" 4.OA.3 4.NBT.6 Lesson 33: Use the area model of division to explain the algorithm Area model for division (when doing this, show the algorithm in correlation with the area model for visual effect) 4.OA.3 4.NBT.6 Lessons 34- 38: Use the area model, array, partial products and place value chart to multiply two-digit factors Area model and array for two-digit multiplication Area model for two digit multiplication Partial products for two digit multiplication Two-digit multiplication algorithm 4.NBT.5
