Distribute plastic bags containing 24 pennies and 3 dimes to each child. To begin this unit, read Alexander Who Used to Be Rich Last Sunday.
Then reread the book and ask the children to work with a friend to
model the amounts he spends, starting with page 12 where he buys some
bubble gum. [There will be enough money if children combine their bags
of money.]
Hold up a penny and ask the children to find a penny in their
bag. Ask them to describe the penny, and record their descriptions on
chart paper. Now ask the children to place a piece of paper over one
penny and to rub the paper with a crayon to make impressions of both
sides of the coin. Ask them to record the coin’s value in both words (1
cent) and using the cent sign (¢). Then repeat the procedure with a
dime.
Next ask the children what similarities and differences they
notice about the coins. Then ask what words they used when they were
talking about the money. As children name them, create a word wall by
writing the words on a poster or on sticky notes and post them in a
prominent place in the classroom.
Ten Frame Activity Sheet
Next give each child a copy of the Ten Frame Activity Sheet. Ask them to use it to find out how to trade the pennies
in their bags for dimes. Model this by placing 1 penny in each cell of
the ten frame, and when the frame is full, exchanging the 10 pennies
for 1 dime. Then ask them to find out how many dimes’ worth of pennies
they have in their bag. [You may wish to remind the children that both
a number (such as 4) and a unit (such as dimes or cents) must be given
to express a quantity.]
Write in a prominent place and call children’s attention to
the cents sign (¢) and the word "cents". Now put the children into
pairs, and give each pair a number cube and a paper bag. Ask the
children to dump the coins from both their plastic bags onto a piece of
paper. Then have the children take turns rolling the number cube, with
one child rolling to tell how many dimes will be put into the paper
bag, and the other child rolling to determine the number of pennies.
After both children have rolled the number cube, ask them to record the
amount they have in the bag in both formats and then to verify their
prediction. Ask them to repeat the activity several times. Students
should record the results on the Paper Bag Activity Sheet.
Paper Bag Activity Sheet
When the children are ready, ask for volunteers to choose one of
the amounts they modeled and show it in coins to the other children.
Then for a first entry for their portfolio, ask the children to write
one amount and draw the coins which show that amount.
