Value of Combinations (Dimes and Pennies) Unit of Study: Money Global Concept Guide: 2 of 3

Content Development Standard Footnote: Students will not be expected to write the decimal form of a coin. For example, a nickel does not need to be written as 0.05. Students will not be expected to write the decimal notation for a combination of coins. “Remember that working with coins requires not only adding up the values but also first mentally giving each coin a value and then ordering the coins. When discussing solutions to situations involving counting of coins, be sure to value any approach that works. However, pay special attention to those students who begin with the larger values and those who put nice combinations together utilizing thinking with 10s.” (Van de Walle, Elementary and Middle School Mathematics, 2010, p. 385-386) In this GCG, students will connect place value of 1, 10, 100 to a penny, dime, and dollar. Students will be expected to use their understanding of counting tens and ones to count a set of dimes and pennies.

Day 1 Essential Question: How can I count sets of dimes and pennies? Engage/Building Conceptual Knowledge: In the lesson Combinations of Pennies and Dimes students will have the opportunity to connect 10 pennies to the value of 1 dime through ten frames. They will then look for additional combinations of pennies and dimes. This lesson includes guiding questions to be used throughout the lesson. Independent Practice: Students can practice building a set value and then use the self check tool. Closure: Dimes and Pennies Exit Ticket. Students will complete the provided exit ticket. Students are expected to count a set of dimes and pennies and draw the coins needed to buy the provided item. This exit ticket extends the work done in class to allow students to make connections to greater amounts. Use students responses to modify lessons for Day 2. By the end of Day 1, students should be able to count a set of dimes and pennies. They should also understand that 1 dime is equal to 10 pennies.

Students will take the performance task on this day. Essential Question: What strategies can I use to find the value of a set of dimes and pennies? Engage: Provide students with a set of dimes and pennies (for example- 3 dimes and 7 pennies). Have the students find the value of the set. As students are working, monitor their strategies. Do any of the students count the dimes first? Do any of the students record their thinking or use mental math of tens and ones? Do any of the students count the number of items in the set rather than the value? Building Conceptual Knowledge: Exchange Pennies/Dimes Game. Students will roll a dice for the number of pennies to be added to the dime/penny place value mat. Once a student has ten pennies, they will exchange/trade a penny for a dime. The goal is to have ten dimes. Students should be able to understand ten pennies can be traded for a dime and the value does not change. If needed, students can record the exchange of pennies and dimes in a math journal/notebook. Independent Practice: Voyages Task Counting Island. Students will select an item card and represent the amount of dimes or pennies needed to purchase this item. For an extension, students could represent the amount of money in another way. Students are only using dimes and pennies for these items. For example, an item that is 13 cents can be represented with 1 dime 3 pennies or 13 pennies. By the end of Day 2, students should be to able to use multiple strategies to find the value of a set of dimes and pennies. Students will take the performance task on this day.
