Mathematics Grade 5 – Unit 1 (SAMPLE)
Mathematics Grade 5 – Unit 1 (SAMPLE) Possible time frame: 25 days Students finalize fluency with multi-digit addition, subtraction, multiplication and division and apply whole number operations to measurement conversion (e.g. convert 12 feet to __yards). Students need experiences with numerical expressions that use grouping symbols to develop understanding of how to use parentheses, brackets, and braces with whole numbers. Students compare like expressions that are grouped differently as well as place grouping symbols in an equation to make it true. Students write simple expressions and interpret the meaning of the numerical expression. In prior grades, students used various strategies to multiply. In Grade 5, students must also understand and be able to use the standard algorithm. In applying the standard algorithm, students recognize the importance of place value. (5.NBT.A.1) In fourth grade, students’ experiences with division were limited to dividing by one-digit divisors. In Grade 5, students extend their prior experiences to include two-digit divisors. They will demonstrate their ability with whole number division using strategies, illustrations, and explanations. Major Cluster Standards Standards Clarification Understand the place value systems. 5.NBT.A.1 and 5.NBT.A.2 Work 5.NBT.A.1 Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it should be limited to whole represents in the place to its left. numbers as this standard will be 5.NBT.A.2 Explain patterns in the number of zeros of the product when multiplying a whole number by powers of 10, and explain patterns in the placement of revisited in Unit 2 and Unit 5. 5.NBT.B.5 Fluency should be the decimal point when a decimal is multiplied or divided by a power of 10.

He also gave 15 cards to Steven, Bobby’s twin brother. Later, Jonas found two new packs of baseball cards in his room. Each pack had 6 regular cards and one limited-edition card. Jonas wrote the following expression to find the number of cards in his collection. 183 − 15 + 15 + 2 × 6 + 1 The expression is missing grouping symbols. Place grouping symbols in the expression so that the result is the number of cards Jonas has left. Explain how you decided where to put the grouping symbols and tell how many cards Jonas has left. 5.

Explain how knowing 50 x 4 = 200 helps you find 500 x 400. 3 Mathematics Grade 5 – Unit 1 (SAMPLE) Sample End of Unit Assessment Task: Lonnie’s class visits a dairy farm to learn about milk production. They learn that the 25 cows on the farm must be milked twice per day (every morning and evening). The cows produce 1,050 gallons of milk per week. 1. How much milk does each cow produce in one day? Show your calculations, and be sure to include units. 2. The farm keeps 20 gallons of the milk produced each day to use on the farm and sells the rest of the milk to a milk distributor to be sold in stores. The farm packages 10 gallons of the milk they keep into gallon containers. The remaining 10 gallons are divided equally between quarts and pints. a. Write and evaluate an expression to find the number of quart-sized containers needed each day. b. Write and evaluate an expression to find the number of pint-sized containers needed each day. c. Explain how you would find the number of quart-sized and pint-sized containers needed each week. 4 Mathematics Grade 5 – Unit 1 (SAMPLE) Sample End-of-unit Assessment Item Responses: 1. 5.NBT.A.1 The value of 7 in 47,358 is 7,000. The value of 7 in 35,739 is 700. 7,000 is 10 times larger than 700. Note: Students might say 700 is 1/10th of 7,000 which is also acceptable. 2. 5.NBT.B.6 The quotient of 3762 ÷ 18 is 209. 3762 = 3600 + 162. 3600 = 36 x 100 36 = 18 x 2 so 3600 = 18 x 2 x 100 or 3600 = 18 x 200. I also know that 18 x 10 = 180 so to get 162 I have to multiply 18 by a number less than 10. 18 x 9 = 162 So, 18 x 200 + 18 x 9 = 3762 18 x (200 + 9) = 3762 18 x 209 = 3762 So the quotient is 209 because the quotient is the unknown factor in the multiplication problem 18 x ____ = 3762. Teacher note: Other methods are acceptable for students to explain/show how they arrived at the answer, including the standard algorithm. However, students are not expected to master the standard algorithm for division until Grade 6 so other methods can and should be used to divide. 3. 5.OA.A.2 a. Jacques wrote 5 × (3 + 9) c. Nadia wrote (9 + 3) × 5 d. Paige wrote (3 + 9) × 5 4. 5.OA.A.1, 5.OA.A.2 The expression should be: 183 − (15 + 15) + 2 × (6 + 1) I know that Jonas gave away 30 cards to his friends Bobby and Steven. In the expression 30 can be found by adding 15 + 15 so I put parentheses around 15 + 15. Then, Jonas found 2 packs of cards that each has 6 regular plus 1 limited-edition card. This means he has 2 packs of 7 cards. In the expression, 6 +1 represents the cards so I put that in parentheses because I have to add that before multiplying by 2 for the two packs. Jonas has 167 baseball cards left. 5 Mathematics Grade 5 – Unit 1 (SAMPLE) 5. 5.OA.A.1, 5.NBT.B.5, 5.NBT.B.6 6. 5.NBT.B.5 The product is 5,598,918. 6 Mathematics Grade 5 – Unit 1 (SAMPLE) 7. 5.MD.A.1, 5.NBT.A.1 To convert 2,500 grams to decagrams, divide 2,500 by 10 because there are 10 grams in 1 decagram. 2,500 grams is the same as 250 decagrams. The value of the digit 5 changed from 500 in 2,500 to 50 in 250. This happened because I divided 2,500 by 10 and 500 divided by 10 is 50. 8. 5.MD.A.1 Answer choice d. 11,232 inches. 9. 5.NBT.A.2 45 x 3 = (40 x 3) + (5 x 3) = 120 + 15 = 135 45 x 30 = (45 x 3) x 10 = 135 x 10 = 1350 450 x 30 = (45 x 10) x (3 x 10) = (45 x 3) x (10 x 10) = 135 x 100 = 13,500 450 x 300 = (45 x 10) x (3 x 100) = (45 x 3) x (10 x 100) = 135 x 1000 = 135,000 For each product, the product 45 x 3 is being multiplied by the next power, or multiple, of 10 (10, 100, 1000). Multiplying 135 by each multiple of 10 increases the number of zeros because the place value of each digit is changing by a factor of 10. 10. 5.NBT.A.1, 5.NBT.A.2 I know that 500 is 10 times 50 and I know that 400 is 100 times 4. 500 x 400 can be rewritten as (50 x 10) x (4 x 100). That means 500 x 400 is 1000 times 50 x 4. So I would only have to multiply 200 by 1000. 7 Mathematics Grade 5 – Unit 1 (SAMPLE) Sample End of Unit Assessment Task Response: 5.NBT.B.5, 5.NBT.B.6, 5.MD.A.1 Lonnie’s class visits a dairy farm to learn about milk production. They learn that the 25 cows on the farm must be milked twice per day (every morning and evening). The cows produce 1,050 gallons of milk per week. 1. How much milk does each cow produce in one day? Show your calculations and be sure to include units. 8 Mathematics Grade 5 – Unit 1 (SAMPLE) 2. The farm keeps 20 gallons of the milk produced each day to use on the farm and sells the rest of the milk to a milk distributor to be sold in stores. The farm packages 10 gallons of the milk they keep into gallon containers. The remaining 10 gallons are divided equally between quarts and pints. a. Write and evaluate an expression to find the number of quart-sized containers needed each day. b. Write and evaluate an expression to find the number of pint-sized containers needed each day. Students might also convert the five gallons to quarts first then to pints. They may also recognize they can use the answer from Part a, and multiply by 2 to get the number of pints. Both alternate methods are acceptable. c. Explain how you would find the number of quart-sized and pint-sized containers needed each week. In order to find the number of quart-sized or pint-sized containers for the week, I would multiply the number of quart-sized containers needed per day by 7 since there are seven days in the week. To find the number of pint-sized containers needed for the week, I would again multiply the number of pint-sized containers needed for one day by 7 since there are seven days in the week. 9 Mathematics Grade 5 – Unit 1 (SAMPLE) Possible Pacing and Sequence of Standards Content and Practice Standards Understand the place value systems. 5.NBT.A.1 Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left. 5.NBT.A.2 Explain patterns in the number of zeros of the product when multiplying a whole number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10.

Application Task Description: Students will determine how much fencing is needed to enclose a pasture given specific measurements and requirements. Students will have to make decisions about the type of materials to use. Students will explain to the ranch owners how they determined what materials to purchase. Days 24-25: End of Unit Assessment 16 Mathematics Grade 5 – Unit 1 (SAMPLE) Application Task: The owners of Dixieland Ranch have hired your group to help determine the amount and the cost of the fencing needed for their pasture. The ranch has an unfenced square pasture that measures 880 yards on each side. In order to drive the tractor into the pasture to complete the chores, the ranch hands need the pasture to have two wide gates installed on the opposite ends of the pasture. The gates come in two different widths: a 10-ft gate and a 12-ft gate. Both gates at opposite ends of the pasture must be the same width. Fence posts will need to be purchased. The fence posts must be spaced evenly around the pasture. The distance between each fence post must be the same as the width of the chosen gate. For example, if you choose to purchase the 10-ft gate, the distance between each fence post will need to be 10-ft. Three rows of barbed wire will be used to construct the fence around the pasture. The owners need your group’s math expertise to help determine which materials to buy, how much of the materials are needed, and how much it will cost to fence in the pasture. Your group will make your decision based on the information given below and your calculations. The owners of the ranch do not wish to spend more than $16,500. The Rancher’s Website sells gates, barbed wire, and posts that will need to be ordered. Rancher’s Website Fall Sale Page Item and Description Gates Barbed Wire 10-ft Center Open Gate (two fence posts needed for installation– not included) 12-ft Center Open Gate (two fence posts needed for installation– not included) $186 per gate $200 per gate 1320-ft roll – 12 gauge wire with 4-pt barbs $75 per roll 50-ft coils – 12 gauge wire with 4-pt barbs $3 per coil Treated Wooden Posts – meant for long term use Fence Posts Cost Sold in bundles of 10 only Untreated Wooden Posts – meant for short term use Sold in bundles of 10 only $130 per bundle of 10 $110 per bundle of 10 You need to create a recommendation to the owners of Dixieland Ranch about the materials they need to order to fence in the pasture. Given the information from the website above decide which materials need to be ordered, the quantity that needs to be ordered, and give the total cost of all items. Use the order form below to record the required information. 17 Mathematics Grade 5 – Unit 1 (SAMPLE) Item Rancher’s Website Order Form Price Type (Cost per Item) Quantity (How many needed) Total Cost Gate Barbed Wire Fence Post TOTAL ORDER AMOUNT After completing the order form, provide a written recommendation to the owners explaining why you chose each of the materials and how you determined the quantity needed.
