Strand: MEASUREMENT AND DATA (2.MD)

Measure and estimate lengths in standard units (Standards 2.MD.1–4) and relate addition and subtraction to length (Standards 2.MD.5–6). They work with time and money (Standards 2.MD.7–8). They represent and interpret data (Standards 2.MD.9–10).

Standard 2.MD.8

Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using \$ and ¢ symbols appropriately. For example, if you have 2 dimes and 3 pennies, how many cents do you have?

• Alexander, Who Used to be Rich Last Sunday
The purpose of this task is for students to find combinations of coins that total the amounts given in a story.
• Choices, Choices, Choices
The purpose of this task is for students to solve problems involving money with prices given in both dollars and cents.
• Delayed Gratification
The purpose of this task is for students to compare two options for a prize where the value of one is given \$2 at a time, giving them an opportunity to "work with equal groups of objects to gain foundations for multiplication."
• Elapsed Time Two
This lesson can be used to help students understand how to read a clock, as well as understand addition and subtraction with time.
• Grade 2 Math Module 7: Problem Solving with Length, Money, and Data (Engage NY)
Module 7 presents an opportunity for students to practice addition and subtraction strategies within 100 and problem-solving skills as they learn to work with various types of units within the contexts of length, money, and data. Students represent categorical and measurement data using picture graphs, bar graphs, and line plots. They revisit measuring and estimating length from Module 2, though now using both metric and customary units.
• Grade 2 Unit 2: Becoming Fluent with Addition and Subtraction (Georgia Standards)
In this unit students will cultivate an understanding of how addition and subtraction affect quantities and are related to each other, will reinforce the multiple meanings for addition (combine, join, and count on) and subtraction (take away, remove, count back, and compare), further develop their understanding of the relationships between addition and subtraction, recognize how the digits 0-9 are used in our place value system to create numbers and manipulate amounts and continue to develop their understanding solving problems with money.
• Grade 2 Unit 4: Applying Base Ten Understanding (Georgia Standards)
In this unit students will continue to develop their understanding of and facility with addition and subtraction, add up to 4 two-digit numbers, use a variety of models (base ten blocks- ones, tens, and hundreds only; diagrams; number lines; place value strategies; etc.) to add and subtract within one thousand and continue to develop their understanding of, and facility with, money.
• IXL Game: Making Change
This game helps second graders solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using \$ and cents symbols appropriately. This is just one of many online games that supports the Utah Math core. Note: The IXL site requires subscription for unlimited use.
• Jamir's Penny Jar
The purpose of this task is to help students articulate their addition strategies as in and would be most appropriately used once students have a solid understanding of coin values. It also provides a context where it makes sense to "skip count by 5s and 10s" for the combinations that involve more than one nickel or dime.
• Math Task: Piggy Banks
Students will find the value of money in piggy banks using the coins, cents, and dollars. They will then arrange the value on a number line.
• Measurement and Data (2.MD) - Second Grade Core Guide
The Utah State Board of Education (USBE) and educators around the state of Utah developed these guides for Second Grade Mathematics - Measurement and Data (2.MD)
• Ordering Time
The purpose of this task is for students to practice reading time shown on both digital and analog clocks and to order a given set of times.
• Pet Shop
The purpose of the task is to use the given prices of stuffed animals at the "pet shop" to solve problems using money. The students need to use their coins or bills to help them solve each problem.
• Primary Economics
The objective of this lesson is to help students recognize and know the value of a penny, nickel, dime and quarter and use various combinations of coins to make money amounts no greater than 25 cents.
• Saving Money 1
The purpose of this task is for students to relate addition and subtraction problems to money and to situations and goals related to saving money.
• Susan's Choice
The purpose of this task is to address the concept of opportunity cost through a real world context involving money.
• Visiting the Arcade
The purpose of this task is to introduce students to the characteristics of money in a financial literacy sense as well as to solve problems involving money.
