Title – Place Value and Number Conservation With Coins

By – Gareth Wicker

Subject – Math

Grade Level – 2nd grade

Objectives: TSWBAT

– count by ones, fives, and tens by counting given amounts of coins

– demonstrate knowledge of place value and number conservation (10 ones = 1
ten, etc.) by “purchasing” items with the correct amount of change in every instance

Intro: Ask if ST have ever used money to purchase anything.
Show penny, nickel, and dime, and ask value of each.

$ tasks:

add amounts of only pennies, nickels, and dimes – separately

add numbers of combined coins

show the same amount in 1, 5, and 10 coins – 10, 20, 30, 40, 50

show amounts in least number of coins possible – 13, 24, 28, 36, 41

Store task:

3 groups of 2 ST

each group has 50 pennies, 5 nickels, and 5 dimes – $1.25

can purchase these items:

pencils .36

erasers .44

stickers small .13 large .21

candy .17

can’t pay in just pennies – must exchange when possible

buy item, other partner gives item and writes “receipt” – $amt and coins to reach amt.

buy items until not enough $ to purchase, then reverse roles

Close: partners exchange coins for other amounts (dime for 10 pennies, 5 pennies for

nickel, etc.)
