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.
Answers will vary. Discuss the fact
that if it is not a day to make
trades, the value of the nickels in
the Nickel jar will not be the total
of all the coins when pennies are
included. The same will be true for
the dimes and quarters.
