2015-2016 Curriculum Blueprint Grade: 2 Course: Mathematics Topic 8 – Work with Time and Money Flexible Time Line 15 days Topic Overview Students will focus on solving problems involving coins and bills, telling time to the nearest 5 minutes using A.M. and P.M., and telling time before and after the hour. Counting money and telling time both require mental mathematics and are related to counting and skip counting by 5 and 10. Counting money is also related to the concepts of place value. Vertical Progression 1st Grade: Students have been introduced to the coins and their value. They can add dimes and pennies. Students tell and write time in hours and half-hours using analog and digital clocks. 3rd Grade: Students use money as a context for word problems in 3rd grade, but do not receive additional instruction regarding money until 4th grade when decimals are introduced. Students read and write time to the nearest minute and calculate elapsed time. Learning Goal Essential Question Students will solve problems about counting money, as well as telling time to the How can you solve problems about counting money or telling time to nearest 5 minutes. the nearest 5 minutes?

Deconstructed Standards MAFS.2.MD.3.7 (DOK 1) Tell and write time from analog and digital clocks to the nearest five minutes. Determine what time is represented by the combination of the number on the clock face and the position of the hands. Tell time using analog clocks to the nearest 5 minutes. Tell time using digital clocks to the nearest 5 minutes. Write time using analog clocks and digital clocks. Identify the hour and minute hand on an analog clock. MAFS.2.MD.3.8 (DOK 2) Solve one and two-step word problems involving dollar bills (singles, fives, tens, twenties, and hundreds) or coins (quarters, dimes, nickels, and pennies) using $ and ¢ symbols appropriately. Word problems may involve addition, subtraction, and equal groups situations 1. Example: The cash register shows that the total for your purchase is 59¢. You gave the cashier three quarters. How much change should you receive from the cashier? a) Identify the value of coins and paper currency. b) Compute the value of any combination of coins within one dollar. c) Compute the value of any combinations of dollars (e.g., If you have three ten-dollar bills, one five-dollar bill, and two one-dollar bills, how much money do you have?). d) Relate the value of pennies, nickels, dimes, and quarters to other coins and to the dollar (e.g., there are five nickels in one quarter. There are two nickels in one dime. There are two and a half dimes in one quarter. There are twenty nickels in one dollar). Identify and recognize the value of dollar bills, quarters, dimes, nickels, and pennies. Identify the $ and the ¢ symbol. Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies using $ and ¢ symbols appropriately. MAFS.2.NBT.1.2 (DOK 1) Count within 1000; skip-count by 5s, 10s, and 100s. Count within 1000. Skip count by 5s to 1000. Skip count by 10s to 1000. Skip count by 100s to 1000. MAFS.2.OA.1.1 (DOK 2) Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem. Identify the unknown in an addition or subtraction word problem. Determine the appropriate operations needed to solve addition and subtraction problems in situations including add to, take from, put together, take apart, and compare. Use drawings or equations to represent one and two step word problems. Add and subtract within 100 to solve one-step word problems with unknowns in any position. Write an addition and subtraction equation with a symbol for the unknown.

Encouraging students to express their mathematical thinking in writing helps them solidify their learning. How can you use skip counting to count coins? What are some different ways to make one dollar using coins? What can you do to help you keep track of the amounts of money in word problems? Which hand moves faster and why? Students write and solve their own word problem involving money. Write to explain how you solved the problem.
