The ongoing project, Hundreds of Coins, was introduced in Unit 1. Activities and possible prompts through Day 25 and Day 100 are included in Unit 1 Lesson 1. Encourage students to skip count using the number line to find the total amount in four jars. Alternatively, students can use a doubling strategy to find out how much is in 2 jars, then in 4 jars. Have coin jars from Unit 1 Lesson 1 and number lines readily available.

    1. 800¢ or $8.00
    2. 40 nickels
    3. 20 dimes

F. Coin Jar

Add one penny to each coin jar.

    1. How many pennies are in each jar?
    2. Do all the jars have the same number of coins?
    3. Do all the jars have the same amount of money? How do you know?
    4. Can we make trades today? Why or why not?
    1. If you collect one penny in each jar for 200 days, how much money will there be altogether?
    2. If you traded pennies for nickels, how many nickels are in the Nickel jar?
    3. If you traded pennies for dimes, how many dimes are in the Dime jar?
