In This Unit of Study…

Students will recognize the values of coins, and they will count groups of coins, which include quarters, dimes, nickels, and pennies. They will also learn to express values of coins with the cent symbol and the values of dollar bills with the dollar symbol.  They are not expected to use decimal values.  Students will also determine relationships of coins based on their values. They will count groups of one type of coin and groups of mixed coins by using strategies such as counting by ones, twos, fives, and tens.  With mixed collections of coins, students will count by larger values first and then by smaller values to find total values.  Students will hear and say the skip count sequences by 5 and 10s in order to assist them in counting pennies, nickels, and dimes.  Students will also count dollar bills as they learn the relationships between the values of a penny, nickel, dime, quarter, and dollar bill.  Students solve contextual word problems involving either dollar bills within $100 or coins within 100¢.  They add and subtract (sums and differences less than or equal to 100) to solve one- and two-step word problems involving money situations of adding to, taking from, putting together, and comparing with unknowns.
