A Place Value and Number Conservation lesson using Coins





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.)
