1340 Week 4 Part 2 Check-in 1.) Solve each of the following story problems by providing a drawing and writing a corresponding multiplication number sentence a.) "Kelli is training to run a race. She runs 3/4 of a mile at a time. If she ran this distance 3 different times, how many miles did she run in all?" b.) "2/3 of Mr. Jeffries class is wearing a green shirt today. Of those students wearing a green shirt, 4/5 are wearing jeans. What fraction of the class is wearing a green shirt and jeans?" 2.) Draw an area model for 5 x . Then, state the product.3.) The following model shows the area model for the computation: 4 x 2-7. Find the product by counting the shaded regions. Show all work to explain how you got this answer from the area model! 4.) Explain why 0.7 x 0.2 = 0. 14. You may choose to explain in words, using a drawing (decimal paper?), through fractions, etc.1340 Week 5 Part 1 Check-in 1.) Classify each word problem as "How many groups?" or "How many in each group?" division. Write a division number sentence and a corresponding multiplication number sentence. Draw a model for each problem. State the final answer with units! a.) If 62 people are attending a wedding and tables hold 8 people per table, how many tables will need to be set up? b.) 4 pencils cost 36 cents. How much does one pencil cost? 2.) Complete the computation 2687 + 4 in each of the following ways: a.) Area model (in reverse) b.) Partial quotients method ("big 7")c.) Scaffold method d.) Long division (this is the standard algorithm for division)1340 Week 5 Part 2 Check-in 1.) Model the following using the common denominator strategy and state the quotient: 2 : 2.) Model the following story problem. State the final answer with units. The length of a piece of string is 12 meters long. If you cut it to create for necklaces that are - meters long, how many necklaces will you have? Will there be any string left over? If so, how much? 3.) Explain why 0.3 = 0. 12 = 2.5. You may choose to explain using decimal paper, in words, converting to fractions, etc.1340 Week 6 Part 1 Check-in 1.) Determine whether each statement is true or false. If false, provide a counterexample. a. The sum of an even number and an odd number is an even number b. If m is a factor of n, then n is a factor of m. 2.) a. Find the prime factorization of the number 8400. b. Is 25 . 3' . 5 a factor of 8400? Explain how you know. 3.) The number 819,750 is divisible by which of the following factors? Use divisibility rules. 2 3 4 5 6 9 10 124.) Use the prime factorization method to determine the GCF and LCM of 250 and 315. Provide a Venn Diagram of prime factors. 5.) Given the following word problem, determine whether finding the GCF or the LCM is appropriate. Then, show work and find the correct answer. White holiday lights come in packages that have 45 light bulbs and multi-colored holiday lights come in packages that have 60 light bulbs. If you want to have the same exact amount of light bulbs of each type, how many light bulbs would you need to purchase? How many packages of each type will you need to purchase
