Here are some LOTD (Letter of the Day) ideas for teaching the Letter Q is for Quarter.
Letter Recognition: Decorate the letter Q with Q-tips
I got the inspiration for making the dots in rows from:
Phonics: Q says /q/ as in quiet. Play the quiet game.
Math: Coin recognition (penny, nickel, dime, quarter) Sorting coins
Color: Silver
Sing this song to learn how to spell silver. Tune: Camp Town Ladies
SIL-VER, silver, silver.
SIL-VER, silver is what that spells.
Shape: Circle
Coin rubbings.
Art: Potato chip can bank
Science: Clean pennies with lemon or lime OR vinegar and 1 tsp salt
Story Time: The Forgotten Penny by Denise Brennan-Nelson
